The geology and geochronology of the Mio-Pliocene sites of the study area have been refined and a reliable chronostratigraphy has been established by 40 Ar/ 39 Ar radiometric dating. The latest Miocene Adu-Asa Formation is divided into four members distinguished from each other by silicic and basaltic tuff marker horizons, most of which are dated basaltic tuffs. Radiometric dating has constrained the age of the Adu-Asa Formation to between 5.2-5.8 Ma. These dates are also supported by paleomagnetic results and biochronology. More than 2,000 fossil specimens were collected from the Adu-Asa Formation between 1992 and 2000. These fossils document 64 mammalian species belonging to 32 genera, 23 families, and 8 orders. This assemblage includes a number of new taxa. Included in the assemblage are First and Last Appearance Datums (FADs and LADs) of some groups, including the earliest record of the hominid genus Ardipithecus. Most of the taxa indicate a predominance of mesic and wooded habitat during the deposition of the Adu-Asa Formation. In these deposits, colobines, viverrids, mustelids, bovines, boselaphines, and tragelaphines are abundant, whereas alcelaphines are absent. Quantitative analyses of biogeographic relationships of the Middle Awash Late Miocene (MALM) mammalian fauna indicate stronger relationships with other African sites than with faunas from Eurasian sites. The MALM deposits have generated a critical dataset for analytic work on past environments, biogeographic relationships, and African vertebrate evolution. Moreover, the geographic position of the Middle Awash, coupled with its precise calibration and chronological span, make it a key section for interpreting latest Miocene faunal interchanges between Africa and Eurasia.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/24642767" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="acc41676e9a8af87b3a8fa6977f1eb6d" rel="nofollow" data-download="{"attachment_id":44968690,"asset_id":24642767,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/44968690/download_file?st=MTczODM0NzQ2NCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="47501576" href="https://independent.academia.edu/YohannesHaileSelassie">Yohannes Haile-Selassie</a><script data-card-contents-for-user="47501576" type="text/json">{"id":47501576,"first_name":"Yohannes","last_name":"Haile-Selassie","domain_name":"independent","page_name":"YohannesHaileSelassie","display_name":"Yohannes Haile-Selassie","profile_url":"https://independent.academia.edu/YohannesHaileSelassie?f_ri=77500","photo":"https://0.academia-photos.com/47501576/97654254/86740619/s65_yohannes.haile-selassie.jpeg"}</script></span></span></li><li class="js-paper-rank-work_24642767 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="24642767"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 24642767, container: ".js-paper-rank-work_24642767", });

The geology and geochronology of the Mio-Pliocene sites of the study area have been refined and a reliable chronostratigraphy has been established by 40 Ar/ 39 Ar radiometric dating. The latest Miocene Adu-Asa Formation is divided into four members distinguished from each other by silicic and basaltic tuff marker horizons, most of which are dated basaltic tuffs. Radiometric dating has constrained the age of the Adu-Asa Formation to between 5.2-5.8 Ma. These dates are also supported by paleomagnetic results and biochronology. More than 2,000 fossil specimens were collected from the Adu-Asa Formation between 1992 and 2000. These fossils document 64 mammalian species belonging to 32 genera, 23 families, and 8 orders. This assemblage includes a number of new taxa. Included in the assemblage are First and Last Appearance Datums (FADs and LADs) of some groups, including the earliest record of the hominid genus Ardipithecus. Most of the taxa indicate a predominance of mesic and wooded habitat during the deposition of the Adu-Asa Formation. In these deposits, colobines, viverrids, mustelids, bovines, boselaphines, and tragelaphines are abundant, whereas alcelaphines are absent. Quantitative analyses of biogeographic relationships of the Middle Awash Late Miocene (MALM) mammalian fauna indicate stronger relationships with other African sites than with faunas from Eurasian sites. The MALM deposits have generated a critical dataset for analytic work on past environments, biogeographic relationships, and African vertebrate evolution. Moreover, the geographic position of the Middle Awash, coupled with its precise calibration and chronological span, make it a key section for interpreting latest Miocene faunal interchanges between Africa and Eurasia.","downloadable_attachments":[{"id":44968690,"asset_id":24642767,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":47501576,"first_name":"Yohannes","last_name":"Haile-Selassie","domain_name":"independent","page_name":"YohannesHaileSelassie","display_name":"Yohannes Haile-Selassie","profile_url":"https://independent.academia.edu/YohannesHaileSelassie?f_ri=77500","photo":"https://0.academia-photos.com/47501576/97654254/86740619/s65_yohannes.haile-selassie.jpeg"}],"research_interests":[{"id":155,"name":"Evolutionary Biology","url":"https://www.academia.edu/Documents/in/Evolutionary_Biology?f_ri=77500","nofollow":true},{"id":406,"name":"Geology","url":"https://www.academia.edu/Documents/in/Geology?f_ri=77500","nofollow":true},{"id":9846,"name":"Ecology","url":"https://www.academia.edu/Documents/in/Ecology?f_ri=77500","nofollow":true},{"id":77500,"name":"Late Miocene","url":"https://www.academia.edu/Documents/in/Late_Miocene?f_ri=77500","nofollow":true},{"id":2155163,"name":"New Taxa","url":"https://www.academia.edu/Documents/in/New_Taxa?f_ri=77500"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_21854197" data-work_id="21854197" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/21854197/Tertiary_and_Quaternary_tectonic_faulting_in_southernmost_Illinois">Tertiary and Quaternary tectonic faulting in southernmost Illinois</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Tertiary and/or Quaternary tectonic faulting is documented in three areas of southernmost Illinois: the Fluorspar Area Fault Complex (FAFC) in Pope and Massac Counties, the Ste.

To quantify region-wide genealogical patterns and to test for the presence of deep intraspecific divergences that have been documented in some other neotropical anurans, we developed a molecular phylogeny of the widespread terrestrial leaflitter frog Eleutherodactylus ockendeni (Leptodactylidae) from 13 localities throughout its range in Ecuador using data from two mitochondrial genes (16S and cyt b; 1246 base pairs). We examined the relation between divergence of mtDNA and the nuclear genome, as sampled by five speciesspecific microsatellite loci, to evaluate indirectly whether lineages are reproductively isolated where they co-occur. Our extensive phylogeographic survey thus assesses the spatial distribution of E. ockendeni genetic diversity across eastern Ecuador. Results: We identified three distinct and well-supported clades within the Ecuadorean range of E. ockendeni: an uplands clade spanning north to south, a northeastern and central lowlands clade, and a central and southeastern clade, which is basal. Clades are separated by 12% to 15% net corrected p-distance for cytochrome b, with comparatively low sequence divergence within clades. Clades marginally overlap in some geographic areas (e.g., Napo River basin) but are reproductively isolated, evidenced by diagnostic differences in microsatellite PCR amplification profiles or DNA repeat number and coalescent analyses (in MDIV) best modelled without migration. Using Bayesian (BEAST) and net phylogenetic estimates, the Southeastern Clade diverged from the Upland/ Lowland clades in the mid-Miocene or late Oligocene. Lowland and Upland clades speciated more recently, in the early or late Miocene. Conclusion: Our findings uncover previously unsuspected cryptic species diversity within the common leaflitter frog E. ockendeni, with at least three different species in Ecuador. While these clades are clearly geographically circumscribed, they do not coincide with any existing landscape barriers. Divergences are ancient, from the Miocene, before the most dramatic mountain building in the Ecuadorean Andes. Therefore, this diversity is not a product of Pleistocene refuges. Our research coupled with other studies suggests that species richness in the upper Amazon is drastically underestimated by current inventories based on morphospecies.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/55415597" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="4d0062f43cf1ca1214b5640c46bee96c" rel="nofollow" data-download="{"attachment_id":71295868,"asset_id":55415597,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/71295868/download_file?st=MTczODM0NzQ2NCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="105270449" href="https://independent.academia.edu/JoseBenitoEscotoDavila">Jose Benito Escoto Davila</a><script data-card-contents-for-user="105270449" type="text/json">{"id":105270449,"first_name":"Jose Benito","last_name":"Escoto Davila","domain_name":"independent","page_name":"JoseBenitoEscotoDavila","display_name":"Jose Benito Escoto Davila","profile_url":"https://independent.academia.edu/JoseBenitoEscotoDavila?f_ri=77500","photo":"https://0.academia-photos.com/105270449/23972212/22965377/s65_jose_benito.escoto_davila.jpg"}</script></span></span></li><li class="js-paper-rank-work_55415597 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="55415597"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 55415597, container: ".js-paper-rank-work_55415597", });

To quantify region-wide genealogical patterns and to test for the presence of deep intraspecific divergences that have been documented in some other neotropical anurans, we developed a molecular phylogeny of the widespread terrestrial leaflitter frog Eleutherodactylus ockendeni (Leptodactylidae) from 13 localities throughout its range in Ecuador using data from two mitochondrial genes (16S and cyt b; 1246 base pairs). We examined the relation between divergence of mtDNA and the nuclear genome, as sampled by five speciesspecific microsatellite loci, to evaluate indirectly whether lineages are reproductively isolated where they co-occur. Our extensive phylogeographic survey thus assesses the spatial distribution of E. ockendeni genetic diversity across eastern Ecuador. Results: We identified three distinct and well-supported clades within the Ecuadorean range of E. ockendeni: an uplands clade spanning north to south, a northeastern and central lowlands clade, and a central and southeastern clade, which is basal. Clades are separated by 12% to 15% net corrected p-distance for cytochrome b, with comparatively low sequence divergence within clades. Clades marginally overlap in some geographic areas (e.g., Napo River basin) but are reproductively isolated, evidenced by diagnostic differences in microsatellite PCR amplification profiles or DNA repeat number and coalescent analyses (in MDIV) best modelled without migration. Using Bayesian (BEAST) and net phylogenetic estimates, the Southeastern Clade diverged from the Upland/ Lowland clades in the mid-Miocene or late Oligocene. Lowland and Upland clades speciated more recently, in the early or late Miocene. Conclusion: Our findings uncover previously unsuspected cryptic species diversity within the common leaflitter frog E. ockendeni, with at least three different species in Ecuador. While these clades are clearly geographically circumscribed, they do not coincide with any existing landscape barriers. Divergences are ancient, from the Miocene, before the most dramatic mountain building in the Ecuadorean Andes. Therefore, this diversity is not a product of Pleistocene refuges. Our research coupled with other studies suggests that species richness in the upper Amazon is drastically underestimated by current inventories based on morphospecies.","downloadable_attachments":[{"id":71295868,"asset_id":55415597,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":105270449,"first_name":"Jose Benito","last_name":"Escoto Davila","domain_name":"independent","page_name":"JoseBenitoEscotoDavila","display_name":"Jose Benito Escoto Davila","profile_url":"https://independent.academia.edu/JoseBenitoEscotoDavila?f_ri=77500","photo":"https://0.academia-photos.com/105270449/23972212/22965377/s65_jose_benito.escoto_davila.jpg"}],"research_interests":[{"id":155,"name":"Evolutionary Biology","url":"https://www.academia.edu/Documents/in/Evolutionary_Biology?f_ri=77500","nofollow":true},{"id":156,"name":"Genetics","url":"https://www.academia.edu/Documents/in/Genetics?f_ri=77500","nofollow":true},{"id":310,"name":"Demography","url":"https://www.academia.edu/Documents/in/Demography?f_ri=77500","nofollow":true},{"id":17439,"name":"Ecuador","url":"https://www.academia.edu/Documents/in/Ecuador?f_ri=77500","nofollow":true},{"id":17825,"name":"Biodiversity","url":"https://www.academia.edu/Documents/in/Biodiversity?f_ri=77500"},{"id":43028,"name":"Genetic Diversity","url":"https://www.academia.edu/Documents/in/Genetic_Diversity?f_ri=77500"},{"id":63093,"name":"Mitochondrial DNA","url":"https://www.academia.edu/Documents/in/Mitochondrial_DNA?f_ri=77500"},{"id":77500,"name":"Late Miocene","url":"https://www.academia.edu/Documents/in/Late_Miocene?f_ri=77500"},{"id":86952,"name":"Haplotypes","url":"https://www.academia.edu/Documents/in/Haplotypes?f_ri=77500"},{"id":133857,"name":"Anura","url":"https://www.academia.edu/Documents/in/Anura?f_ri=77500"},{"id":151749,"name":"Molecular phylogeny","url":"https://www.academia.edu/Documents/in/Molecular_phylogeny?f_ri=77500"},{"id":160843,"name":"Cryptic Species","url":"https://www.academia.edu/Documents/in/Cryptic_Species?f_ri=77500"},{"id":338814,"name":"Cytochrome B","url":"https://www.academia.edu/Documents/in/Cytochrome_B?f_ri=77500"},{"id":577933,"name":"Genetic variation","url":"https://www.academia.edu/Documents/in/Genetic_variation?f_ri=77500"},{"id":725929,"name":"Amazon basin","url":"https://www.academia.edu/Documents/in/Amazon_basin?f_ri=77500"},{"id":880279,"name":"Bayes Theorem","url":"https://www.academia.edu/Documents/in/Bayes_Theorem-1?f_ri=77500"},{"id":1232430,"name":"Genetic Markers","url":"https://www.academia.edu/Documents/in/Genetic_Markers?f_ri=77500"},{"id":2783638,"name":"microsatellite loci","url":"https://www.academia.edu/Documents/in/microsatellite_loci?f_ri=77500"},{"id":3203621,"name":"Gene frequency","url":"https://www.academia.edu/Documents/in/Gene_frequency?f_ri=77500"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_69168029" data-work_id="69168029" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/69168029/Reflection_seismic_study_across_the_continental_shelf_of_Baba_Burnu_promontory_of_Biga_Peninsula_northwest_Turkey">Reflection seismic study across the continental shelf of Baba Burnu promontory of Biga Peninsula, northwest Turkey</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Seismic and structural characteristics of the continental shelf of Baba Burnu promontory of Biga Peninsula, northwest Turkey were investigated by 67 km of multi-channel seismic re¯ection survey.

The synthetic sequence considered is based on five classical sections from the Caltanissetta Basin. Our interpretations are based on the recognition of autochthonous, allochthonous and reworked population among the dinocyst assemblages. For the first time, sea-surface temperatures and seasonal salinity contrasts were tentatively reconstructed using a ''Mutual Climatic Range Method''. Sicilian late Tortonian deposits correspond to marine environment with significant terrestrial inputs favourable to eutrophic dinocyst species. Immediately after the beginning of the Messinian Stage, euryhaline assemblages took place, followed by meso-hyperhaline taxa, within a general trend to shallowing. At the end of the Tripoli diatomitic Formation, environment appears confined, with regular oceanic inflows. Such marine inflows remain persistent during the deposition of the salt Member, witnessing the probable persistence of nearby normal marine sea-surface water conditions in the Mediterranean Sea but with possible reduced hydrological circulation and/or low nutrient component. Such inflows are slightly decreasing up to the top of the Sicilian Upper Evaporites. At the same time, river inputs appear weak during the salt deposition, as the consequence of a rather dry climatic context. As shown by reworking activity, terrestrial inputs increase progressively from the base of the Upper Evaporites. During the Lago Mare period, while climate remains rather dry (absence of freshwater algae inputs, very low amount in trees requiring humid conditions), local deposition environment is confined with mesohaline to hypohaline sea-surface waters, in a context with relatively high seasonal sea-surface salinity contrast (up to 6%). The very high reworking observed in the Arenazzolo silts, in addition to slightly increasing water depth, led us to consider the presence of a discontinuity between the Lago Mare and the Arenazzolo Fms. We consider the Arenazzolo Formation as a transgressive facies following a deep downcutting period. The Arenazzolo Formation presents a two-step development. The first one, correlative with the presence of a G. etrusca (a species with Paratethyan affinities), corresponds to a relative high-stand sea-level with oceanic influxes, low seasonal sea-surface salinity contrast and probable more humid context, as revealed by the important freshwater algal inputs. During the second step, salinity becomes much more variable, with a clear increase of seasonal sea-surface salinity contrast, a possible slight mean sea-surface temperature increase (only few degrees) and a clear weakening of the river inputs. Taking the proposed Zanclean position of the Arenazzolo Fm. into consideration, we state that mean sea-surface temperature did not change significantly from the base of the Messinian to the earliest Zanclean. At 5.33 Ma, the suddenly achieved flooding restored a fair, deep oceanic environment characterized, at the beginning, by a clear mean sea-surface temperature cooling (up to 6-7 8C) and a nutrient depletion, associated with the basins starvation. Sea-surface salinities were normal, with very low seasonal contrast. Hydrodynamics then nutrient supply became then quite normal from c.a. 5.08 Ma. The status of the Sicilian Caltanissetta Basin as a marginal basin although fastly deepening and the stratigraphical location of the Messinian discontinuity at the base of the Arenazzolo is the scenario that best matches our dinocyst record. # 2007 Elsevier Masson SAS.

Until now, evidence of cyanobacteria has not been reported in any studies of ancient DNA older than a few thousand years. Here, we investigate morphologically, biochemically and genetically primary evaporites deposited in situ during the late Miocene (Messinian) Salinity Crisis from the north-eastern Apennines of Italy. The evaporites contain fossilized bacterial structures having identical morphological forms as modern microbes. We successfully extracted and amplified genetic material belonging to ancient cyanobacteria from gypsum crystals dating back to 5.910-5.816 Ma, when the Mediterranean became a giant hypersaline brine pool. This finding represents the oldest ancient cyanobacterial DNA to date. Our clone library and its phylogenetic comparison with present cyanobacterial populations point to a marine origin for the depositional basin. This investigation opens the possibility of including fossil cyanobacterial DNA into the palaeo-reconstruction of various environments and could also be used to quantify the ecological importance of cyanobacteria through geological time. These genetic markers serve as biosignatures providing important clues about ancient life and begin a new discussion concerning the debate on the origin of late Miocene evaporites in the Mediterranean.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/3423250" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="57a8362b73c3bf1b63582f918478df42" rel="nofollow" data-download="{"attachment_id":31197163,"asset_id":3423250,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/31197163/download_file?st=MTczODM0NzQ2NCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="3991443" href="https://independent.academia.edu/GiulianaPanieri">Giuliana Panieri</a><script data-card-contents-for-user="3991443" type="text/json">{"id":3991443,"first_name":"Giuliana","last_name":"Panieri","domain_name":"independent","page_name":"GiulianaPanieri","display_name":"Giuliana Panieri","profile_url":"https://independent.academia.edu/GiulianaPanieri?f_ri=77500","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_3423250 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="3423250"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 3423250, container: ".js-paper-rank-work_3423250", });

Until now, evidence of cyanobacteria has not been reported in any studies of ancient DNA older than a few thousand years. Here, we investigate morphologically, biochemically and genetically primary evaporites deposited in situ during the late Miocene (Messinian) Salinity Crisis from the north-eastern Apennines of Italy. The evaporites contain fossilized bacterial structures having identical morphological forms as modern microbes. We successfully extracted and amplified genetic material belonging to ancient cyanobacteria from gypsum crystals dating back to 5.910-5.816 Ma, when the Mediterranean became a giant hypersaline brine pool. This finding represents the oldest ancient cyanobacterial DNA to date. Our clone library and its phylogenetic comparison with present cyanobacterial populations point to a marine origin for the depositional basin. This investigation opens the possibility of including fossil cyanobacterial DNA into the palaeo-reconstruction of various environments and could also be used to quantify the ecological importance of cyanobacteria through geological time. These genetic markers serve as biosignatures providing important clues about ancient life and begin a new discussion concerning the debate on the origin of late Miocene evaporites in the Mediterranean.","downloadable_attachments":[{"id":31197163,"asset_id":3423250,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":3991443,"first_name":"Giuliana","last_name":"Panieri","domain_name":"independent","page_name":"GiulianaPanieri","display_name":"Giuliana Panieri","profile_url":"https://independent.academia.edu/GiulianaPanieri?f_ri=77500","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":406,"name":"Geology","url":"https://www.academia.edu/Documents/in/Geology?f_ri=77500","nofollow":true},{"id":407,"name":"Geochemistry","url":"https://www.academia.edu/Documents/in/Geochemistry?f_ri=77500","nofollow":true},{"id":417,"name":"Paleontology","url":"https://www.academia.edu/Documents/in/Paleontology?f_ri=77500","nofollow":true},{"id":3869,"name":"Geobiology","url":"https://www.academia.edu/Documents/in/Geobiology?f_ri=77500","nofollow":true},{"id":4967,"name":"Molecular Evolution","url":"https://www.academia.edu/Documents/in/Molecular_Evolution?f_ri=77500"},{"id":9752,"name":"Cyanobacteria","url":"https://www.academia.edu/Documents/in/Cyanobacteria?f_ri=77500"},{"id":9846,"name":"Ecology","url":"https://www.academia.edu/Documents/in/Ecology?f_ri=77500"},{"id":10655,"name":"Scanning Electron Microscopy","url":"https://www.academia.edu/Documents/in/Scanning_Electron_Microscopy?f_ri=77500"},{"id":12597,"name":"Crystallization","url":"https://www.academia.edu/Documents/in/Crystallization?f_ri=77500"},{"id":45213,"name":"Italy","url":"https://www.academia.edu/Documents/in/Italy?f_ri=77500"},{"id":54433,"name":"Phylogeny","url":"https://www.academia.edu/Documents/in/Phylogeny?f_ri=77500"},{"id":77500,"name":"Late Miocene","url":"https://www.academia.edu/Documents/in/Late_Miocene?f_ri=77500"},{"id":90326,"name":"Fossils","url":"https://www.academia.edu/Documents/in/Fossils?f_ri=77500"},{"id":1256666,"name":"Geologic Sediments","url":"https://www.academia.edu/Documents/in/Geologic_Sediments?f_ri=77500"},{"id":1344950,"name":"Calcium Sulfate","url":"https://www.academia.edu/Documents/in/Calcium_Sulfate?f_ri=77500"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_60943706" data-work_id="60943706" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/60943706/The_Tonalitic_Lamellae_along_the_Giudicarie_Fault_System_age_data_and_tectonic_implications">The Tonalitic Lamellae along the Giudicarie Fault System: age data and tectonic implications</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">The NNE-SSW striking Giudicarie Fault System (composed of the Northern and Southern Giudicarie Fault and the Meran-Mauls Fault) represents a distinctive bend and offset in the Periadriatic Fault System (PFS).

These two features are the product of multiple ice sheet advances and retreats on the continental shelf. In this paper, we present a reconstruction of paleo-bathymetric profiles of the Eastern Ross Sea throughout the Cenozoic. The evolution of the sea-floor morphology from shallow and seaward dipping to the present-day configuration gives new insights into the understanding of the West Antarctic Ice Ž . Sheet WAIS history in this sector. Paleo-bathymetric profiles have been calculated by applying a reverse post-rift modelling, starting from a cross-section derived from multichannel seismic data. The post-rift reverse modelling includes: sediment decompaction, isostatic compensation after removing and recovering sediments of the post-rift thermal subsidence. The major uncertainty in our model is due to the paucity of stratigraphic constraints for the late Miocene and Pliocene sequences that prevents precise values of paleowater-depth being estimated. Nevertheless, major changes in the shape of the continental shelf and slope throughout the Cenozoic can be recognised, and mark some critical steps in the Ross Sea Ž . Ž evolution. 1 Pre-Miocene: the Eastern Ross Sea was a deep structural basin bordered to the west by areas e.g., the Central . High outcropping the sea level and hosting valley glaciers or small ice caps. A continental shelf edge was not clearly Ž . developed yet, the eastern flank of the Central High appeared as an inclined ramp, dipping towards the ocean. 2 Early to middle Miocene: tectonic subsidence gradually produced a marine flooding over most of the pre-Miocene sub-aerial areas. A continental shelf, slope and rise are gradually delineated. The shelf profile was seaward dipping and not yet overdeepened.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/14210000" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="0a2484b715df4124889bde28a2ef796e" rel="nofollow" data-download="{"attachment_id":44462659,"asset_id":14210000,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/44462659/download_file?st=MTczODM0NzQ2NCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="33159636" href="https://independent.academia.edu/LuigiTorelli">Luigi Torelli</a><script data-card-contents-for-user="33159636" type="text/json">{"id":33159636,"first_name":"Luigi","last_name":"Torelli","domain_name":"independent","page_name":"LuigiTorelli","display_name":"Luigi Torelli","profile_url":"https://independent.academia.edu/LuigiTorelli?f_ri=77500","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_14210000 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="14210000"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 14210000, container: ".js-paper-rank-work_14210000", });

These two features are the product of multiple ice sheet advances and retreats on the continental shelf. In this paper, we present a reconstruction of paleo-bathymetric profiles of the Eastern Ross Sea throughout the Cenozoic. The evolution of the sea-floor morphology from shallow and seaward dipping to the present-day configuration gives new insights into the understanding of the West Antarctic Ice Ž . Sheet WAIS history in this sector. Paleo-bathymetric profiles have been calculated by applying a reverse post-rift modelling, starting from a cross-section derived from multichannel seismic data. The post-rift reverse modelling includes: sediment decompaction, isostatic compensation after removing and recovering sediments of the post-rift thermal subsidence. The major uncertainty in our model is due to the paucity of stratigraphic constraints for the late Miocene and Pliocene sequences that prevents precise values of paleowater-depth being estimated. Nevertheless, major changes in the shape of the continental shelf and slope throughout the Cenozoic can be recognised, and mark some critical steps in the Ross Sea Ž . Ž evolution. 1 Pre-Miocene: the Eastern Ross Sea was a deep structural basin bordered to the west by areas e.g., the Central . High outcropping the sea level and hosting valley glaciers or small ice caps. A continental shelf edge was not clearly Ž . developed yet, the eastern flank of the Central High appeared as an inclined ramp, dipping towards the ocean. 2 Early to middle Miocene: tectonic subsidence gradually produced a marine flooding over most of the pre-Miocene sub-aerial areas. A continental shelf, slope and rise are gradually delineated. The shelf profile was seaward dipping and not yet overdeepened.","downloadable_attachments":[{"id":44462659,"asset_id":14210000,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":33159636,"first_name":"Luigi","last_name":"Torelli","domain_name":"independent","page_name":"LuigiTorelli","display_name":"Luigi Torelli","profile_url":"https://independent.academia.edu/LuigiTorelli?f_ri=77500","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":400,"name":"Earth Sciences","url":"https://www.academia.edu/Documents/in/Earth_Sciences?f_ri=77500","nofollow":true},{"id":18625,"name":"Sea Level","url":"https://www.academia.edu/Documents/in/Sea_Level?f_ri=77500","nofollow":true},{"id":77500,"name":"Late Miocene","url":"https://www.academia.edu/Documents/in/Late_Miocene?f_ri=77500","nofollow":true},{"id":122774,"name":"Seismic stratigraphy","url":"https://www.academia.edu/Documents/in/Seismic_stratigraphy?f_ri=77500","nofollow":true},{"id":230435,"name":"Continental shelf","url":"https://www.academia.edu/Documents/in/Continental_shelf?f_ri=77500"},{"id":404000,"name":"Cross Section","url":"https://www.academia.edu/Documents/in/Cross_Section?f_ri=77500"},{"id":768076,"name":"West Antarctic Ice Sheet","url":"https://www.academia.edu/Documents/in/West_Antarctic_Ice_Sheet?f_ri=77500"},{"id":958658,"name":"Ice Sheets","url":"https://www.academia.edu/Documents/in/Ice_Sheets?f_ri=77500"},{"id":982932,"name":"Ross Sea","url":"https://www.academia.edu/Documents/in/Ross_Sea?f_ri=77500"},{"id":1010773,"name":"Middle Miocene","url":"https://www.academia.edu/Documents/in/Middle_Miocene?f_ri=77500"},{"id":1242196,"name":"Water Depth","url":"https://www.academia.edu/Documents/in/Water_Depth?f_ri=77500"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_3196507" data-work_id="3196507" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/3196507/Molecular_phylogenetics_and_historical_biogeography_of_Hawaiian_Dryopteris_Dryopteridaceae_">Molecular phylogenetics and historical biogeography of Hawaiian Dryopteris (Dryopteridaceae)</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">The fern genus Dryopteris (Dryopteridaceae) is represented in the Hawaiian Islands by 18 endemic taxa and one non-endemic, native species.

The goals of this study were to determine whether Dryopteris in Hawai’i is monophyletic and to infer the biogeographical origins of Hawaiian Dryopteris by determining the geographical distributions of their closest living relatives. We sequenced two chloroplast DNA fragments, rbcL and the trnL-F intergenic spacer (IGS), for 18 Hawaiian taxa, 45 non-Hawaiian taxa, and two outgroup species. For individual fragments, we estimated phylogenetic relationships using Bayesian inference and maximum parsimony. We performed a combined analysis of both cpDNA fragments employing Bayesian inference, maximum parsimony, and maximum likelihood. These analyses indicate that Hawaiian Dryopteris is not monophyletic, and that there were at least five separate colonizations of the Hawaiian Islands by different species of dryopteroid ferns, with most of the five groups having closest relatives in SE Asia. The results suggest that one colonizing ancestor, perhaps from SE Asia, gave rise to eight endemic taxa (the glabra group). Another colonizing ancestor, also possibly from SE Asia, gave rise to a group of five endemic taxa (the exindusiate group). Dryopteris fusco-atra and its two varieties, which are endemic to Hawai’i, most likely diversified from a SE Asian ancestor. The Hawaiian endemic Nothoperanema rubiginosum has its closest relatives in SE Asia, and while the remaining two species, D. wallichiana and D. subbipinnata, are sister species, their biogeographical origins could not be determined from these analyses due to the widespread distributions of D. wallichiana and its closest non-Hawaiian relative.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/3196507" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="397ed2d98314f6181349c274d692d10f" rel="nofollow" data-download="{"attachment_id":31079047,"asset_id":3196507,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/31079047/download_file?st=MTczODM0NzQ2NCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="2702859" href="https://manoa-hawaii.academia.edu/TomRanker">Tom Ranker</a><script data-card-contents-for-user="2702859" type="text/json">{"id":2702859,"first_name":"Tom","last_name":"Ranker","domain_name":"manoa-hawaii","page_name":"TomRanker","display_name":"Tom Ranker","profile_url":"https://manoa-hawaii.academia.edu/TomRanker?f_ri=77500","photo":"https://0.academia-photos.com/2702859/868060/1083166/s65_tom.ranker.jpg"}</script></span></span></li><li class="js-paper-rank-work_3196507 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="3196507"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 3196507, container: ".js-paper-rank-work_3196507", });

This paper aims at characterizing two dikes of likely Late Miocene age (Casa Carpini dikes), previously defined as lamprophyres (i.e. kersantite), outcropping in eastern Elba, on the eastern and southern slopes of the Monte Arco, close to Porto Azzurro. The grey to light-grey Casa Carpini dikes, the phyllites and metasandstones of the Ligurian-Piedmontese Acquadolce Unit, are quartz-diorites in composition with a maximum of 23% of mafic minerals (biotite). They show a microcrystalline porphyritic texture consisting of plagioclase, biotite, quartz, K-feldspar, and rare muscovite with scattered xenocrysts of quartz, plagioclase and K-feldspar. Plagioclase phenocrysts display normal zoning with An% = 9-23; the variability of An in the plagioclase microcrysts is wider (5-34%). The REE patterns are characterised by fractionated LREE and MREE and negative anomaly of Eu. The mantle-normalized trace element patterns show high content of the most incompatible elements with a positive spike of Th and Pb, and high LILE/HFSE ratios. Negative spikes of Nb, P and Ti are also observable. No negative anomalies of Sr are present, and Ce/Sr ratios are much lower than other magmatic rocks from Elba. A depletion in K, Rb and Cs is also observed in the studies rocks, possibly a result of secondary processes. Sr-Nd isotopic ratios for the two outcrops of the studied dikes show significant differences, with I dicchi di Casa Carpini, di colore grigio e grigio chiaro che tagliano le filladi e le meta-arenarie dell'Unità Ligure-Piedemontese-Acquadolce, sono delle quarzo-dioriti contenenti fino al 23% di minerali femici (biotite). Essi presentano una tessitura microcristallina porfirica costituita da plagioclasio, biotite, quarzo, K-feldspato, e rara muscovite in cui sono dispersi xenocristalli di quarzo, plagioclasio e K-feldspato. I fenocristalli di plagioclasio presentano un contenuto di Anortite (An) variabile nell'intervallo 9-23% e deboli zonature normali; la variabilità del contenuto di An è più ampia nei microcristalli (5-34%). I pattern delle REE sono caratterizzati da LREE e MREE frazionate e anomalia negativa di Eu. Il pattern degli elementi in tracce mostra arricchimento negli elementi più incompatibili e alti rapporti LILE/HFSE; sono osservabili, inoltre, arricchimento in Th e Pb, impoverimento in Nb, P e Ti. Non è presente anomalia negativa di Sr ed i rapporti Ce/Sr sono più bassi che in molte altre rocce dell'isola d'Elba. Un impoverimento in K, Rb e Cs, forse legato a processi di alterazione secondaria, caratterizza le rocce studiate. Fra i due dicchi di Casa Carpini esistono modeste ma significative differenze dei rapporti isotopici dello Sr (0,711845 e 0,711769) e del Nd (0,512223 and 0,512246). Essi sono petrograficamente diversi da molti dei dicchi associati ai plutoni granitici e alle laccoliti dell'isola d'Elba. Analogie si osservano, invece, con: porfidi di Orano a composizione granodioritica e quarzo-monzonitica, gli ultimi prodotti magmatici dell'Elba occidentale. Le caratteristiche petrologiche e geochimiche dei dicchi di Casa Carpini sono tipiche delle rocce intermedioacide dell'isola d'Elba. Come altre rocce dell'isola, mostrano evidenze petrografiche e geochimiche di mixing fra un magma calcalcalino, intermedio-femico, del tipo Capraia e un fuso crostale anatettico. Tuttavia, le loro caratteristiche geochimiche suggeriscono un ruolo dei magmi femici più importante rispetto al resto del magmatismo elbano.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/19474791" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="56b61a475edad565c42cc80fc546df26" rel="nofollow" data-download="{"attachment_id":40640692,"asset_id":19474791,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/40640692/download_file?st=MTczODM0NzQ2NCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="901682" href="https://unifi.academia.edu/albasanto">alba santo</a><script data-card-contents-for-user="901682" type="text/json">{"id":901682,"first_name":"alba","last_name":"santo","domain_name":"unifi","page_name":"albasanto","display_name":"alba santo","profile_url":"https://unifi.academia.edu/albasanto?f_ri=77500","photo":"https://0.academia-photos.com/901682/2811883/118892874/s65_alba.santo.jpg"}</script></span></span></li><li class="js-paper-rank-work_19474791 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="19474791"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 19474791, container: ".js-paper-rank-work_19474791", });

Moreover, pyroclastic and epiclastic deposits occur throughout the terrigenous and biogenic sequence, which indicates intense synchronous volcanic activity, directly linked to the faulting. The Charo alluvial-lacustrine sequences crop out extensively to the south of the present Cuitzeo Lake and their exposures record the development and spreading of Late Miocene and Pliocene alluvial-lacustrine zones. The resulting sequences are up to 40 m thick and record four major evolutionary stages related with specific tectonic and volcanic events, which caused changes in the basin morphometry and the palaeodrainage conditions. The first of these stages (Late Miocene) caused the generation of small, NE-SW-oriented shallow lacustrine and swampy zones, which resulted from the activity of strike-slip faults with the same orientation. Alluvial deposits and shallow lacustrine diatomaceous horizons were deposited during this stage. The second stage (Early Pliocene) gave rise to the formation of NE-SW-trending basins related to the extensional reactivation of the earlier NE-SW strike-slip faults. Within this second stage the Charo-Morelia lacustrine depocentre became a larger, deeper tropical lake. The planktonic and planktonic-facultative lacustrine diatom floral assemblages record the development during this stage of a major lake transgression, which could be caused both by wetter climate and tectonic watershed and drainage rearrangement. The third and fourth stages (Quaternary) were related to widespread block tilting processes, which were linked to the generation of E-W-oriented extensional faults and which resulted in the shifting and restriction of the larger, perennial, steadier lacustrine zones to the present Cuitzeo Lake. To the south of this lake the sedimentary record of this stage started with widespread fluvial sequences, which erosively overlaid the diatomitic deposits. The lacustrine zones developed during this alluvial-dominated stage were restricted to small depressions and consisted of small lakes and pond-related environments, which were fed by ephemeral fluvial currents. These minor water bodies were infilled and overlain by acidic pyroclastic fall deposits developed during a major volcanic episode which affected the Charo-Morelia sub-basin (fourth stage). The Cuitzeo and other ancient to recent lacustrine systems (i.e. Chapala Lake) evolved in the Trans-Mexican Volcanic Belt as a result of its tectono-volcanic evolution, which largely influenced the highly sensitive lacustrine systems. Therefore, the analysis of the development, sedimentary evolution and shifting of the lacustrine zones may help us to understand the structural evolution of the central Mexican igneous arc complex and the</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/51868606" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="edb1b4e1d92139e8c916eb2e49186d1e" rel="nofollow" data-download="{"attachment_id":69397916,"asset_id":51868606,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/69397916/download_file?st=MTczODM0NzQ2NCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="170586703" href="https://independent.academia.edu/IsabelIsradeAlcantara">Isabel Israde Alcantara</a><script data-card-contents-for-user="170586703" type="text/json">{"id":170586703,"first_name":"Isabel","last_name":"Israde Alcantara","domain_name":"independent","page_name":"IsabelIsradeAlcantara","display_name":"Isabel Israde Alcantara","profile_url":"https://independent.academia.edu/IsabelIsradeAlcantara?f_ri=77500","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_51868606 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="51868606"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 51868606, container: ".js-paper-rank-work_51868606", });

The Charo alluvial-lacustrine sequences crop out extensively to the south of the present Cuitzeo Lake and their exposures record the development and spreading of Late Miocene and Pliocene alluvial-lacustrine zones. The resulting sequences are up to 40 m thick and record four major evolutionary stages related with specific tectonic and volcanic events, which caused changes in the basin morphometry and the palaeodrainage conditions.

Our interpretations are more accurate than previous hypotheses because i) they are more sensitive to lower temperatures (<60 C), ii) we directly compare data obtained from in-situ and detrital rocks, and iii) they are constrained by recently published palaeomagnetic, stratigraphic and geochronological data. The response of the buttressing Ecuadorian margin to the collision of the Caribbean Plateau and its overlying arc was diachronous. Exhumation occurred as an immediate response to collision at w75 Ma, south of S1 30 0 , whereas the northern region started to exhume at w65 Ma, suggesting that accretion may have been oblique. Elevated cooling and exhumation rates within specific massifs dispersed along the entire length of the Ecuadorian cordilleras, during 43e30 and 25e18 Ma, are attributed to i) an increase in convergence rates between the Farallon and South American plates during 42e37 Ma, and an increase in spreading rates in the southern Atlantic ocean, and ii) a change in the vector of the subducting plate, which changed from ESE to E at 25 Ma in response to fragmentation of the Farallon Plate. Previous suggestions that Eocene reactivation of the buttressing margin were driven by collision of the Macuchi Arc are shown to be incorrect. 40 Ar/ 39 Ar, zircon fission track, and apatite fission track and (UeTh)/He analyses from the Eastern Cordillera north of S1 30 0 reveal well defined periods of rapid cooling and exhumation at 15 Ma, 9e7 Ma and 5.5e0 Ma. Apatite (UeTh)/He data reveals late Miocene-Recent cooling and exhumation ( 1.3 km) of the southern Eastern Cordillera by a lower quantity than that experienced to the north (!3.5 km). These distinguishable differences in cooling and exhumation are attributed to the collision of the Carnegie Ridge with the northern SOAM Plate at 15 Ma, and the subsequent subduction of high topography along the ridge at w5 Ma, which reactivated the serpentinised Campanian suture via dextral transcurrent displacement.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/5953412" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="096ccc9c9155ccdf61a0f96502c46cfb" rel="nofollow" data-download="{"attachment_id":49077688,"asset_id":5953412,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/49077688/download_file?st=MTczODM0NzQ2NCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="8864829" href="https://ethz.academia.edu/winklerw">Wilfried Winkler</a><script data-card-contents-for-user="8864829" type="text/json">{"id":8864829,"first_name":"Wilfried","last_name":"Winkler","domain_name":"ethz","page_name":"winklerw","display_name":"Wilfried Winkler","profile_url":"https://ethz.academia.edu/winklerw?f_ri=77500","photo":"https://0.academia-photos.com/8864829/3044672/3579033/s65_wilfried.winkler.jpg"}</script></span></span></li><li class="js-paper-rank-work_5953412 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="5953412"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 5953412, container: ".js-paper-rank-work_5953412", });

Our interpretations are more accurate than previous hypotheses because i) they are more sensitive to lower temperatures (\u003c60 C), ii) we directly compare data obtained from in-situ and detrital rocks, and iii) they are constrained by recently published palaeomagnetic, stratigraphic and geochronological data. The response of the buttressing Ecuadorian margin to the collision of the Caribbean Plateau and its overlying arc was diachronous. Exhumation occurred as an immediate response to collision at w75 Ma, south of S1 30 0 , whereas the northern region started to exhume at w65 Ma, suggesting that accretion may have been oblique. Elevated cooling and exhumation rates within specific massifs dispersed along the entire length of the Ecuadorian cordilleras, during 43e30 and 25e18 Ma, are attributed to i) an increase in convergence rates between the Farallon and South American plates during 42e37 Ma, and an increase in spreading rates in the southern Atlantic ocean, and ii) a change in the vector of the subducting plate, which changed from ESE to E at 25 Ma in response to fragmentation of the Farallon Plate. Previous suggestions that Eocene reactivation of the buttressing margin were driven by collision of the Macuchi Arc are shown to be incorrect. 40 Ar/ 39 Ar, zircon fission track, and apatite fission track and (UeTh)/He analyses from the Eastern Cordillera north of S1 30 0 reveal well defined periods of rapid cooling and exhumation at 15 Ma, 9e7 Ma and 5.5e0 Ma.

The stumps occupying an area of about 50 × 100 m have been preserved in Upper Miocene grey sands overlying the lignite seam. The height of the trunks ranges from 2 up to 5.2 m, their perimeter at the base reaches up to 8.8 m. The age of the fossil remains is estimated to about 7 Ma according to the regional stratigraphy. The fossil forest is the remains of a swamp forest which is also corroborated by the palaeogeography of the fossil site as the area of the former Lake Pannon. Fossil leaf and fruit assemblages indicating the typical swamp vegetation in the close vicinity of Lake Pannon have already been reported from the site. Wood anatomy of some of the stumps is diagnostic for Taxodioxylon germanicum (Greguss) Van der Burgh which is related to modern Sequoia Endlicher and was an important element of peat forming vegetation during the Neogene.

The stumps occupying an area of about 50 × 100 m have been preserved in Upper Miocene grey sands overlying the lignite seam. The height of the trunks ranges from 2 up to 5.2 m, their perimeter at the base reaches up to 8.8 m. The age of the fossil remains is estimated to about 7 Ma according to the regional stratigraphy. The fossil forest is the remains of a swamp forest which is also corroborated by the palaeogeography of the fossil site as the area of the former Lake Pannon. Fossil leaf and fruit assemblages indicating the typical swamp vegetation in the close vicinity of Lake Pannon have already been reported from the site. Wood anatomy of some of the stumps is diagnostic for Taxodioxylon germanicum (Greguss) Van der Burgh which is related to modern Sequoia Endlicher and was an important element of peat forming vegetation during the Neogene. Some other stumps are comparable to Glyptostroboxylon Conwentz emend. Dolezych \u0026 Van der Burgh.

the Sicily Channel rift zone, integrated with offshore geophysical information, are used to derive the structural setting of the Island and the surrounding region, and to analyse the relationships between tectonics and magmatism. Field work shows that the principal faults exposed on the Island fall into two systems trending NNE-SSW and NW-SE. Mapped faults from offshore multichannel seismic profiles show similar trends, and some of them represent the offshore extension of the Pantelleria Island structures. The NW-SE faults bound the Pantelleria Graben, one of the three main depressions formed since the Late Miocene-Early Pliocene within the African continental platform, which compose the Sicily Channel rift zone. A 3-D Moho depth geometry, derived from inversion of Bouguer gravity data, shows a significant uplift of the discontinuity up to 16-17 km beneath the westernmost part of the Pantelleria Graben and beneath the Pantelleria Island; it lows rapidly to 24-25 km away from the graben northeastward and south-westward. The Moho uplift could explain the presence of a shallow magma chamber in the southern part of the Island, where processes of magmatic differentiation are documented. Geological and geophysical data suggest that the northwestern part of the Sicily Channel is presently dominated by a roughly E-W directed extensional regime. Crustal cracking feeding the Quaternary volcanism could be also related to this extensional field that would be further responsible for the development of the N-S trending volcanic belt that extends in the Sicily Channel from Lampedusa Island to the Graham Bank. This mode of deformation is confirmed also by geodetic data. This implies that in the northwestern part of the Sicily Channel, the E-W extension replaced the NE-SW crustal stretching that originated the NW-trending tectonic depressions constituting the rift zone.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/23464717" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="6bddf52930ccaacb76e4a2a14118ed14" rel="nofollow" data-download="{"attachment_id":43902554,"asset_id":23464717,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/43902554/download_file?st=MTczODM0NzQ2NCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="45358790" href="https://independent.academia.edu/Lodolo">Emanuele Lodolo</a><script data-card-contents-for-user="45358790" type="text/json">{"id":45358790,"first_name":"Emanuele","last_name":"Lodolo","domain_name":"independent","page_name":"Lodolo","display_name":"Emanuele Lodolo","profile_url":"https://independent.academia.edu/Lodolo?f_ri=77500","photo":"https://0.academia-photos.com/45358790/42699121/34176397/s65_emanuele.lodolo.jpg"}</script></span></span></li><li class="js-paper-rank-work_23464717 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="23464717"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 23464717, container: ".js-paper-rank-work_23464717", });

Field work shows that the principal faults exposed on the Island fall into two systems trending NNE-SSW and NW-SE. Mapped faults from offshore multichannel seismic profiles show similar trends, and some of them represent the offshore extension of the Pantelleria Island structures. The NW-SE faults bound the Pantelleria Graben, one of the three main depressions formed since the Late Miocene-Early Pliocene within the African continental platform, which compose the Sicily Channel rift zone. A 3-D Moho depth geometry, derived from inversion of Bouguer gravity data, shows a significant uplift of the discontinuity up to 16-17 km beneath the westernmost part of the Pantelleria Graben and beneath the Pantelleria Island; it lows rapidly to 24-25 km away from the graben northeastward and south-westward. The Moho uplift could explain the presence of a shallow magma chamber in the southern part of the Island, where processes of magmatic differentiation are documented. Geological and geophysical data suggest that the northwestern part of the Sicily Channel is presently dominated by a roughly E-W directed extensional regime. Crustal cracking feeding the Quaternary volcanism could be also related to this extensional field that would be further responsible for the development of the N-S trending volcanic belt that extends in the Sicily Channel from Lampedusa Island to the Graham Bank. This mode of deformation is confirmed also by geodetic data. This implies that in the northwestern part of the Sicily Channel, the E-W extension replaced the NE-SW crustal stretching that originated the NW-trending tectonic depressions constituting the rift zone.","downloadable_attachments":[{"id":43902554,"asset_id":23464717,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":45358790,"first_name":"Emanuele","last_name":"Lodolo","domain_name":"independent","page_name":"Lodolo","display_name":"Emanuele Lodolo","profile_url":"https://independent.academia.edu/Lodolo?f_ri=77500","photo":"https://0.academia-photos.com/45358790/42699121/34176397/s65_emanuele.lodolo.jpg"}],"research_interests":[{"id":400,"name":"Earth Sciences","url":"https://www.academia.edu/Documents/in/Earth_Sciences?f_ri=77500","nofollow":true},{"id":3110,"name":"Marine Geology","url":"https://www.academia.edu/Documents/in/Marine_Geology?f_ri=77500","nofollow":true},{"id":32153,"name":"Structural Analysis","url":"https://www.academia.edu/Documents/in/Structural_Analysis?f_ri=77500","nofollow":true},{"id":77500,"name":"Late Miocene","url":"https://www.academia.edu/Documents/in/Late_Miocene?f_ri=77500","nofollow":true},{"id":184909,"name":"Structure Analysis","url":"https://www.academia.edu/Documents/in/Structure_Analysis?f_ri=77500"},{"id":415322,"name":"Magma Chamber","url":"https://www.academia.edu/Documents/in/Magma_Chamber?f_ri=77500"},{"id":1254922,"name":"Late Quaternary","url":"https://www.academia.edu/Documents/in/Late_Quaternary?f_ri=77500"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_9174495" data-work_id="9174495" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/9174495/Multiple_in_to_Africa_dispersals_of_labeonin_fishes_Teleostei_Cyprinidae_revealed_by_molecular_phylogenetic_analysis">Multiple in-to-Africa dispersals of labeonin fishes (Teleostei: Cyprinidae) revealed by molecular phylogenetic analysis</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">An out-of-Africa dispersal route has been proposed for many organisms, including modern man.

However, counter examples of in-to-Africa dispersal routes are less common. In the present article, the phylogenetic relationships within the Labeoninae, a subfamily of cyprinid fishes distributed in Asia and Africa, were analyzed to investigate the biogeographic processes governing the modern distribution of these Asian and African cyprinids. The mitochondrial DNA cytochrome b gene was used as a molecular marker. The phylogenetic analysis indicated that the subfamily Labeoninae is a monophyletic group, with some Asian labeonins located at the basal position. Two subclades were found that contained both African and Asian species, which highlighted a need for further biogeographic analysis. Based on this analysis, it is proposed that the centre of origin of the Labeoninae was in East Asia. Molecular clock estimation suggests that the Labeoninae arose by the Early Miocene (~23 MYA) during the period of the second Tibetan uplift. Subsequently, two dispersal events of labeonins from Asia into Africa occured in the Early Miocene (~ 20 MYA) and Late Miocene (~9 MYA) and serve as examples counter to out-of-Africa dispersal.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/9174495" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="73518e88a3f8e73aa18cadfa4733eb41" rel="nofollow" data-download="{"attachment_id":47861636,"asset_id":9174495,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/47861636/download_file?st=MTczODM0NzQ2NCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="20957579" href="https://addisababa.academia.edu/abebeGetahun">abebe Getahun</a><script data-card-contents-for-user="20957579" type="text/json">{"id":20957579,"first_name":"abebe","last_name":"Getahun","domain_name":"addisababa","page_name":"abebeGetahun","display_name":"abebe Getahun","profile_url":"https://addisababa.academia.edu/abebeGetahun?f_ri=77500","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_9174495 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="9174495"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 9174495, container: ".js-paper-rank-work_9174495", });

In addition, the authors discuss biogeographic hypotheses regarding the origin of South American tremarctines. The Tremarctinae subfamily is distributed exclusively in America, from Alaska to southern Patagonia. Its biochron comprises the temporal lapse between Late Miocene and recent times; the first record of Tremarctinae in North America corresponds to the Hemphillian and the last to the Rancholabrean. In South America, the first record corresponds to the Ensenadan. In the present day, it corresponds to the only living tremarctine, the 'Andean Bear,' but short-faced bears became extinct during the early Holocene. The extinction of short-faced bears in North and South America appears to have been approximately synchronous. Finally, the fossil record in South America indicates species turnover between the Ensenadan and Bonaerian, during which time the giant species Arctotherium angustidens was replaced by Arctotherium tarijense, Arctotherium bonaeriense, and Arctotherium vetustum (and probably Arctotherium wingei). q</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/29941442" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="88b36f844bea7e0d8d842651c6509b02" rel="nofollow" data-download="{"attachment_id":50399165,"asset_id":29941442,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/50399165/download_file?st=MTczODM0NzQ2NCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="50422154" href="https://independent.academia.edu/etonni">eduardo tonni</a><script data-card-contents-for-user="50422154" type="text/json">{"id":50422154,"first_name":"eduardo","last_name":"tonni","domain_name":"independent","page_name":"etonni","display_name":"eduardo tonni","profile_url":"https://independent.academia.edu/etonni?f_ri=77500","photo":"https://0.academia-photos.com/50422154/22129340/21364685/s65_eduardo.tonni.jpg"}</script></span></span></li><li class="js-paper-rank-work_29941442 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="29941442"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 29941442, container: ".js-paper-rank-work_29941442", });

In addition, the authors discuss biogeographic hypotheses regarding the origin of South American tremarctines. The Tremarctinae subfamily is distributed exclusively in America, from Alaska to southern Patagonia. Its biochron comprises the temporal lapse between Late Miocene and recent times; the first record of Tremarctinae in North America corresponds to the Hemphillian and the last to the Rancholabrean. In South America, the first record corresponds to the Ensenadan. In the present day, it corresponds to the only living tremarctine, the 'Andean Bear,' but short-faced bears became extinct during the early Holocene. The extinction of short-faced bears in North and South America appears to have been approximately synchronous. Finally, the fossil record in South America indicates species turnover between the Ensenadan and Bonaerian, during which time the giant species Arctotherium angustidens was replaced by Arctotherium tarijense, Arctotherium bonaeriense, and Arctotherium vetustum (and probably Arctotherium wingei). q","downloadable_attachments":[{"id":50399165,"asset_id":29941442,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":50422154,"first_name":"eduardo","last_name":"tonni","domain_name":"independent","page_name":"etonni","display_name":"eduardo tonni","profile_url":"https://independent.academia.edu/etonni?f_ri=77500","photo":"https://0.academia-photos.com/50422154/22129340/21364685/s65_eduardo.tonni.jpg"}],"research_interests":[{"id":406,"name":"Geology","url":"https://www.academia.edu/Documents/in/Geology?f_ri=77500","nofollow":true},{"id":409,"name":"Geophysics","url":"https://www.academia.edu/Documents/in/Geophysics?f_ri=77500","nofollow":true},{"id":10770,"name":"Biostratigraphy","url":"https://www.academia.edu/Documents/in/Biostratigraphy?f_ri=77500","nofollow":true},{"id":57423,"name":"Fossil record","url":"https://www.academia.edu/Documents/in/Fossil_record?f_ri=77500","nofollow":true},{"id":60387,"name":"Patagonia","url":"https://www.academia.edu/Documents/in/Patagonia?f_ri=77500"},{"id":77500,"name":"Late Miocene","url":"https://www.academia.edu/Documents/in/Late_Miocene?f_ri=77500"},{"id":146424,"name":"Indicator species","url":"https://www.academia.edu/Documents/in/Indicator_species?f_ri=77500"},{"id":176798,"name":"South America","url":"https://www.academia.edu/Documents/in/South_America?f_ri=77500"},{"id":253469,"name":"North America","url":"https://www.academia.edu/Documents/in/North_America?f_ri=77500"},{"id":299411,"name":"First record","url":"https://www.academia.edu/Documents/in/First_record?f_ri=77500"},{"id":338205,"name":"Early Holocene","url":"https://www.academia.edu/Documents/in/Early_Holocene?f_ri=77500"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_5837621" data-work_id="5837621" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/5837621/Palaeomagnetic_remanences_in_high_grade_metamorphic_rocks_of_the_Everest_region_indication_for_Late_Miocene_crustal_doming">Palaeomagnetic remanences in high-grade metamorphic rocks of the Everest region: indication for Late Miocene crustal doming</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">High-grade metamorphic rocks of the upper amphibolite to granulite facies in the Higher Himalayan crystalline (HHC) were studied for their appropriateness for palaeomagnetic investigations.

Sampling and fieldwork was accomplished on a south-north transect at ˜87°E in the Khumbu region south of Everest. Paragenesis of iron-sulphides and oxides was found to be variable due to different source rocks and metamorphic conditions in this area. Unblocking temperature ranges, isothermal remanence acquisition, low-temperature magnetic properties and microscopic observations confirm the presence of pyrrhotite and magnetite. Two remanence components were separated with unblocking temperature intervals of 250-330 °C and 370-550 °C, which can be attributed to characteristic remanent magnetizations (ChRM) of monoclinic pyrrhotite (ChRMpyr) and magnetite (ChRMmag), respectively. Mainly the ChRMpyr showed a consistent demagnetization behaviour, probably residing in pyrrhotite particles within the single domain to pseudo-single domain range. Normal and reverse polarities were observed, partly co-existing within the unblocking spectrum of single specimens; this (i) supports a thermoremanent (TRM) origin of the ChRMpyr and (ii) indicates that the time span of remanence acquisition was long enough to average out palaeosecular variation. The age of the ChRMpyr can be related to the last metamorphic cooling event at the Early to Late Miocene boundary (16 Ma). The ChRMmag is probably a secondary chemical or thermochemical remanence acquired by hydrothermal processes during retrogression. ChRMpyr and ChRMmag directions are similar suggesting that pyrrhotite and magnetite were magnetized approximately contemporaneously. Separation of the sampling area into three sectors reveals a south-north trend with (i) variable block rotations in the southernmost part close to the Main Central Thrust (five sites), (ii) no rotation in the area between Lukla and Namche (10 sites) and (iii) a significant clockwise rotation (N= 5 sites, D/I= 42.3°/29.4°, k= 20.7, α95= 17.2°) along the Imja Khola north of Namche. We interpret the clockwise rotation as an apparent rotation due to tilting by crustal doming in the Everest region. This doming obviously occurred north of a fault zone located at around Namche and was not affecting the region south of it. The clockwise sense of the apparent vertical-axis rotation indicates that the area north of Namche is located at the western side of the dome structure where westward tilting around a subhorizontal axis occurred (best fit: tilt direction 277°, tilt angle 51°).</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/5837621" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="c8ce473b42a020a1244cf7c480a922dd" rel="nofollow" data-download="{"attachment_id":49116768,"asset_id":5837621,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/49116768/download_file?st=MTczODM0NzQ2NCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="8587460" href="https://independent.academia.edu/LaluPaudel">Lalu Paudel</a><script data-card-contents-for-user="8587460" type="text/json">{"id":8587460,"first_name":"Lalu","last_name":"Paudel","domain_name":"independent","page_name":"LaluPaudel","display_name":"Lalu Paudel","profile_url":"https://independent.academia.edu/LaluPaudel?f_ri=77500","photo":"https://0.academia-photos.com/8587460/154770130/144388065/s65_lalu.paudel.jpeg"}</script></span></span></li><li class="js-paper-rank-work_5837621 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="5837621"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 5837621, container: ".js-paper-rank-work_5837621", });

The fossils from the new locality come from the Baynunah Formation which is largely composed of fluvial deposits. The bird remains from Ruwais and other late Miocene localities with Baynunah Formation deposits are here described. The taxa and material represented are Struthioformidae eggshell, and Anhinga sp. and Ardeidae postcranial skeletal material. The presence of a modern genus in the Miocene has prompted a discussion here of the maximum age of modern genera in the fossil record, which in many cases appears to be Neogene. The latter can in turn lead to the identification of modern species because a past member of a modern genus falls within the size range of a modern species.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/720715" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="93488dd6c5ed8d7c14310983998ca2a4" rel="nofollow" data-download="{"attachment_id":4473771,"asset_id":720715,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/4473771/download_file?st=MTczODM0NzQ2NCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="431117" href="https://york.academia.edu/MarkBeech">Mark Beech</a><script data-card-contents-for-user="431117" type="text/json">{"id":431117,"first_name":"Mark","last_name":"Beech","domain_name":"york","page_name":"MarkBeech","display_name":"Mark Beech","profile_url":"https://york.academia.edu/MarkBeech?f_ri=77500","photo":"https://0.academia-photos.com/431117/106312/153281739/s65_mark.beech.jpg"}</script></span></span></li><li class="js-paper-rank-work_720715 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="720715"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 720715, container: ".js-paper-rank-work_720715", });

The fossils from the new locality come from the Baynunah Formation which is largely composed of fluvial deposits. The bird remains from Ruwais and other late Miocene localities with Baynunah Formation deposits are here described. The taxa and material represented are Struthioformidae eggshell, and Anhinga sp. and Ardeidae postcranial skeletal material. The presence of a modern genus in the Miocene has prompted a discussion here of the maximum age of modern genera in the fossil record, which in many cases appears to be Neogene. The latter can in turn lead to the identification of modern species because a past member of a modern genus falls within the size range of a modern species.","downloadable_attachments":[{"id":4473771,"asset_id":720715,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":431117,"first_name":"Mark","last_name":"Beech","domain_name":"york","page_name":"MarkBeech","display_name":"Mark Beech","profile_url":"https://york.academia.edu/MarkBeech?f_ri=77500","photo":"https://0.academia-photos.com/431117/106312/153281739/s65_mark.beech.jpg"}],"research_interests":[{"id":73832,"name":"Abu Dhabi","url":"https://www.academia.edu/Documents/in/Abu_Dhabi?f_ri=77500","nofollow":true},{"id":77500,"name":"Late Miocene","url":"https://www.academia.edu/Documents/in/Late_Miocene?f_ri=77500","nofollow":true},{"id":90326,"name":"Fossils","url":"https://www.academia.edu/Documents/in/Fossils?f_ri=77500","nofollow":true},{"id":96324,"name":"Birds","url":"https://www.academia.edu/Documents/in/Birds?f_ri=77500","nofollow":true},{"id":165536,"name":"Al Gharbia","url":"https://www.academia.edu/Documents/in/Al_Gharbia?f_ri=77500"},{"id":165807,"name":"Ruwais","url":"https://www.academia.edu/Documents/in/Ruwais?f_ri=77500"},{"id":165808,"name":"Baynunah Formation","url":"https://www.academia.edu/Documents/in/Baynunah_Formation?f_ri=77500"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_9799876" data-work_id="9799876" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/9799876/The_long_term_evolution_of_the_Congo_deep_sea_fan_A_basin_wide_view_of_the_interaction_between_a_giant_submarine_fan_and_a_mature_passive_margin_ZaiAngo_project">The long-term evolution of the Congo deep-sea fan: A basin-wide view of the interaction between a giant submarine fan and a mature passive margin (ZaiAngo project</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">We have integrated the relatively unknown distal domains of the Lower Congo basin, where the main depocenters of the Congo submarine fan are located, with the better-constrained successions on the shelf and upper slope, through the... <a class="more_link u-tcGrayDark u-linkUnstyled" data-container=".work_9799876" data-show=".complete" data-hide=".summarized" data-more-link-behavior="true" href="#">more</a></div><div class="complete hidden">We have integrated the relatively unknown distal domains of the Lower Congo basin, where the main depocenters of the Congo submarine fan are located, with the better-constrained successions on the shelf and upper slope, through the analysis of thousands of km of 2D seismic reflection profiles offshore the Congo-Angola passive margin. The basin architecture is depicted by two ca. 800-km-long regional cross sections through the northern (Congo) and southern (Angola) margin. A large unit deposited basinward of the Aptian salt limit is likely to be the abyssal-plain equivalent of the upper-Cretaceous carbonate shelf that characterized the first post-rift deposits in West-equatorial African margins. A latest-Turonian shelf-deepening event is recorded in the abyssal plain as a long period (Coniacian-Eocene) of condensed sedimentation and basin starvation. The onset of the giant Tertiary Congo deep-sea fan in early Oligocene following this event reactivates the abyssal plain as the main depocenter of the basin. The time-space partitioning of sedimentation within the deep-sea fan results from the interplay among increasing sediment supply, margin uplift, rise of the Angola salt ridge, and canyon incision throughout the Neogene. Oligocene-early Miocene turbidite sedimentation occurs mainly in NW-SE grabens and ponded inter-diapir basins on the southern margin (Angola). Seaward tilting of the margin and downslope salt withdrawal activates the up-building of the Angola escarpment, which leads to a northward (Congo) shift of the transfer zones during late Miocene. Around the Miocene-Pliocene boundary, the incision of the Congo submarine canyon confines the turbidite flows and drives a general basinward progradation of the submarine fan into the abyssal plain The slope deposition is dominated by fine-grained hemipelagic deposits ever since.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/9799876" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="066b372b37830911aeebf37f2d2d1a4e" rel="nofollow" data-download="{"attachment_id":35972719,"asset_id":9799876,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/35972719/download_file?st=MTczODM0NzQ2NCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="23613533" href="https://independent.academia.edu/MichelLopez1">Michel Lopez</a><script data-card-contents-for-user="23613533" type="text/json">{"id":23613533,"first_name":"Michel","last_name":"Lopez","domain_name":"independent","page_name":"MichelLopez1","display_name":"Michel Lopez","profile_url":"https://independent.academia.edu/MichelLopez1?f_ri=77500","photo":"https://0.academia-photos.com/23613533/9680294/10781489/s65_michel.lopez.jpg_oh_beb2d0e53e8536f5d0830ef3fb504b55_oe_55ee2bb1___gda___1445414999_329313cc158b0af0d400fe8bc8c02aae"}</script></span></span></li><li class="js-paper-rank-work_9799876 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="9799876"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 9799876, container: ".js-paper-rank-work_9799876", });

Outside the rift, a concurrent volcanic activity occurred mainly along transversal tectonic lineaments, the most important of which is the Yerer-Tullu Wellel Volcano-Tectonic Lineament (YTVL) developing for $500 km westward of Addis Abeba.

In this study, these volcanic belts are referred to as the Sanandaj Cretaceous volcanic (SCV), Sonqor-Baneh volcanic (SBV), and Hamedan-Tabriz volcanic (HTV) belts, respectively. The SCV belt consists mainly of mafic to intermediate submarine rocks with calc-alkaline affinity, and the SBV belt is composed of basalt, gabbro to dioritic bodies, with extrusive to subvolcanic magmatic textures and tholeiitic to alkaline affinity. These extend along the MZT between the Zagros ophiolite in the west and the SCV belt in the east. The HTV belt is part of the Urmieh-Dokhtar Magmatic Arc belt that extends across the Hamedan to Tabriz, and was active in the Miocene to Quaternary. The petrology and geochemistry of the northwestern Iranian volcanic zones indicate that they were generated at an active continental margin. In addition to the volcanic belts, there is a dismembered ophiolite along the MZT from Kermanshah to Turkey, in a NW-SE direction. These ophiolites are remnants of Neo-Tethyan oceanic crust which was obducted over the Arabian passive margin in the late Cretaceous. In this study, we propose that a collision between the Arabian and Iranian plates may have occurred in the middle to late Miocene, and that the Neo-Tethyan oceanic subduction beneath northwestern Iran ceased for a while. As a result, a gap in volcanic activity occurred between the Cretaceous and the Middle Miocene-Quaternary volcanism events. This gap in activity is not observed in southwestern Iran.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/54413586" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="71452a073b4a602bc62c589b3367c558" rel="nofollow" data-download="{"attachment_id":70788607,"asset_id":54413586,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/70788607/download_file?st=MTczODM0NzQ2NCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="16479789" href="https://uok.academia.edu/hosseinazizi">hossein azizi</a><script data-card-contents-for-user="16479789" type="text/json">{"id":16479789,"first_name":"hossein","last_name":"azizi","domain_name":"uok","page_name":"hosseinazizi","display_name":"hossein azizi","profile_url":"https://uok.academia.edu/hosseinazizi?f_ri=77500","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_54413586 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="54413586"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 54413586, container: ".js-paper-rank-work_54413586", });

Gravity cores, water samples and video observations were also collected at selected sites. Mapped domes were found from 50 to 200 m wide and no more than 5 m high occurring on the seafloor, isolated or arranged in clusters. Ridges consisted of large tabular sub-elongated structures, elevated from 5 to 10 m from the surrounding seafloor, and had flat tops on which numerous closeset, small cones occurred, appearing in video observation as carbonate buildings strongly colonized by gorgonians. Characteristic acoustic signatures (i.e. blank areas and/or turbidity zones and enhanced reflections in seismic records), measured gas anomalies in seawater samples and detected plumes on echosounder profiles suggest that both the domes and ridges are influenced by active seeps. In addition, their spatial distribution reflected patterns of tectonic lineaments produced by the late Miocene to present-day geo-dynamic evolution of the Malta plateau, which is also an important hydrocarbon province. Results from gravity cores suggest that mud extrusion seems to be the main process responsible for the origin of the domes, which are formed by gray mud with only a few centimeters of biogenic sand at the top, indicating that recent bioclastic material is not a major contributor to mound building. However, at present, active degassing appears to be the main process that controls the morphological and sedimentological expression of both the domes and ridges. Therefore, a quiescent or intermittent active stage for mud extrusion is considered.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/9023603" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="6bbeb2059af9a9bee2203164ab980169" rel="nofollow" data-download="{"attachment_id":47911770,"asset_id":9023603,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/47911770/download_file?st=MTczODM0NzQ2NCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="20319486" href="https://unimib.academia.edu/AlessandraSavini">Alessandra Savini</a><script data-card-contents-for-user="20319486" type="text/json">{"id":20319486,"first_name":"Alessandra","last_name":"Savini","domain_name":"unimib","page_name":"AlessandraSavini","display_name":"Alessandra Savini","profile_url":"https://unimib.academia.edu/AlessandraSavini?f_ri=77500","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_9023603 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="9023603"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 9023603, container: ".js-paper-rank-work_9023603", });

Gravity cores, water samples and video observations were also collected at selected sites. Mapped domes were found from 50 to 200 m wide and no more than 5 m high occurring on the seafloor, isolated or arranged in clusters. Ridges consisted of large tabular sub-elongated structures, elevated from 5 to 10 m from the surrounding seafloor, and had flat tops on which numerous closeset, small cones occurred, appearing in video observation as carbonate buildings strongly colonized by gorgonians. Characteristic acoustic signatures (i.e. blank areas and/or turbidity zones and enhanced reflections in seismic records), measured gas anomalies in seawater samples and detected plumes on echosounder profiles suggest that both the domes and ridges are influenced by active seeps. In addition, their spatial distribution reflected patterns of tectonic lineaments produced by the late Miocene to present-day geo-dynamic evolution of the Malta plateau, which is also an important hydrocarbon province. Results from gravity cores suggest that mud extrusion seems to be the main process responsible for the origin of the domes, which are formed by gray mud with only a few centimeters of biogenic sand at the top, indicating that recent bioclastic material is not a major contributor to mound building. However, at present, active degassing appears to be the main process that controls the morphological and sedimentological expression of both the domes and ridges. Therefore, a quiescent or intermittent active stage for mud extrusion is considered.","downloadable_attachments":[{"id":47911770,"asset_id":9023603,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":20319486,"first_name":"Alessandra","last_name":"Savini","domain_name":"unimib","page_name":"AlessandraSavini","display_name":"Alessandra Savini","profile_url":"https://unimib.academia.edu/AlessandraSavini?f_ri=77500","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":406,"name":"Geology","url":"https://www.academia.edu/Documents/in/Geology?f_ri=77500","nofollow":true},{"id":409,"name":"Geophysics","url":"https://www.academia.edu/Documents/in/Geophysics?f_ri=77500","nofollow":true},{"id":50243,"name":"Mediterranean Sea","url":"https://www.academia.edu/Documents/in/Mediterranean_Sea?f_ri=77500","nofollow":true},{"id":77500,"name":"Late Miocene","url":"https://www.academia.edu/Documents/in/Late_Miocene?f_ri=77500","nofollow":true},{"id":116383,"name":"Environmental Control","url":"https://www.academia.edu/Documents/in/Environmental_Control?f_ri=77500"},{"id":156347,"name":"Methane","url":"https://www.academia.edu/Documents/in/Methane?f_ri=77500"},{"id":236377,"name":"Spatial Distribution","url":"https://www.academia.edu/Documents/in/Spatial_Distribution?f_ri=77500"},{"id":549044,"name":"Eastern Mediterranean","url":"https://www.academia.edu/Documents/in/Eastern_Mediterranean?f_ri=77500"},{"id":1242196,"name":"Water Depth","url":"https://www.academia.edu/Documents/in/Water_Depth?f_ri=77500"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_10859815" data-work_id="10859815" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/10859815/Mar%C3%A8s_Quarries_on_the_Majorcan_Coast_Spain_as_Geological_Heritage_Sites">Marès Quarries on the Majorcan Coast (Spain) as Geological Heritage Sites</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Marès is a soft rock, generally pale-coloured rock, composed mainly of bioclastic calcareous sandstone which ranges in age from the Late Miocene to the Quaternary, although it dates predominantly from the Pleistocene.

This rock was traditionally the main material for construction on the island, with the Palma Cathedral being a classic example. There are numerous marès quarries on the eastern and southern coast of Majorca, some of which are very well exposed in the cliffs. The stone is quarried in large blocks which are later divided into smaller ones. This quarrying process creates deep, vertical quarry walls orientated, both parallel and perpendicular to the coast, which gives an excellent exposure of the rock and clear views of its internal structure. In 2006, the first inventory of geosites on the Balearic Islands was carried out with the aim of defining the geological and hydrogeological heritage in the region. Of the 35 geosites inventoried and catalogued on the island of Majorca, two of them are marès quarries: Estret des Temps on the Santanyi coast and Es Carnatge on the coast of Palma. Both are representative of Pleistocene aeolianites, with excellent exposure of the sets of cross-bedding, while the Estret des Temps quarry also contains noteworthy exposures of hoof prints of Myotragus balearicus, a small endemic goat which became extinct with the arrival of the first human inhabitants of the island, around 7,000 BC. In this study, we propose the inclusion of a new site in the geosites inventory, the Roman quarry of Es Molar de Cala Pi in Llucmajor, where an exceptional sequence of Late-Miocene beaches facies can be observed, including a coquina with large-scale and high-angle cross-bedding and anemone tubes at the base of the quarry. The sequence is crowned by a system of Pleistocene palaeodunes. Such exposure conditions and facies sedimentological variety, coupled with the representativeness of the record, make this quarry a unique site for the study of the Neogene and Quaternary on Majorca</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/10859815" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="d9bcbf559218f6f4db7a3aa374503a70" rel="nofollow" data-download="{"attachment_id":47070195,"asset_id":10859815,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/47070195/download_file?st=MTczODM0NzQ2NCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="26382491" href="https://igme-es.academia.edu/PedroRobledo">Pedro Robledo</a><script data-card-contents-for-user="26382491" type="text/json">{"id":26382491,"first_name":"Pedro","last_name":"Robledo","domain_name":"igme-es","page_name":"PedroRobledo","display_name":"Pedro Robledo","profile_url":"https://igme-es.academia.edu/PedroRobledo?f_ri=77500","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_10859815 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="10859815"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 10859815, container: ".js-paper-rank-work_10859815", });

It consists of a number of marine platforms and produces oil from different reservoirs of different geological ages from the Lower Cretaceous to the Miocene. The aim of this study was to enhance a seismic-log evaluational procedure to evaluate the Miocene-aged Asl and Hawara Formations which encounter the main hydrocarbon and source rock potentials in the area North of October Oil Field. The well logging data, the borehole seismic data, and the velocity surveys are all used in this study. A number of synthetic seismograms are constructed and interpreted together with the deduced seismic impedance and reflection coefficient data for many wells in the study area. In addition, a comprehensive velocity analysis is performed using the seismic times and the computed average and interval velocities. These seismic-derived parameters are primarily used in recognizing and locating precisely the marl and sand sections of Asl Formation which show low to middle amplitudes. Furthermore, a quantitative well logging analysis is carried out over Asl and Hawara Formations to shed light over their hydrocarbon potentiality. Good oil saturation is exhibited by the Asl sand section which reaches to more than 90% in the southern parts of the study area. The petrophysical characters of this sand are very good in terms of good effective porosity (9% to13%), low shale volume (V sh S h > 85%). The sections of the Asl marl and the Hawara shale on the other hand are considered completely wet. An integrated model making use of the seismic- and log-derived properties is applied over the two studied formations for better understanding the reservoir of interest. Many relations are constructed between velocity, seismic impedance, and the rock pore spaces on one hand and between the velocity, lithology, and fluid content on the other hand. This study revealed that the sand section attains very good oil-bearing potentiality in the study area and proved that the application of an integrated model of the log- and seismic-derived properties led to an enhanced evaluation of the Asl and Hawara Formations, good discrimination between their lithological components besides precise differentiation from the overlying Middle to Late Miocene sections. يعد حقل أكتوبر للزيت أحد أهم حقول البترول البحرية Off-shore المنتجة للزيت في خليج السويس بمصر، فهو يتكون من مجموعه من الأرصفة البحريةPlatforms و ينتج من عده خزانات ذات عصور جيولوجية مختلفة تتراوح من الطباشيري السفلي إلي الميوسين. تهدف هذه الدراسة إلي تطبيق نموذج تقييمي يعتمد علي خواص مشتقه من البيانات السيزمية و تسجيلات الآبار و ذلك لتقييم تكويني "عسل" و "هواره" ذا العصر الميوسيني، حيث يحوي هذان التكوينان علي الجهود الهيدروكربونيةHydrocarbon Potentiality و المصدرية الرئيسية للزيت في منطقه شمال حقل أكتوبر. استخدم في هذه الدراسة العديد من تسجيلات الآبار بالإضافة إلي البيانات السيزمية البئرية و بيانات تسجيلات السرعة. كما تم إنشاء و تفسير مجموعه من السيزموجرامات التخليقية Synthetic seismograms مع كل من الممانعة الصوتية و معامل الانعكاس للعديد من الآبار في منطقه الدراسة. بالاضافه إلي هذا تم عمل تحليل كمي للسرعة باستخدام الزمن السيزمي و السرعات المتوسطة و الفترية المقاسة. هذا وقد استخدمت المعاملات المشتقة من البيانات السيزمية بصفه أساسيه و بدقه في تعيين و تحديد نطاقات المارل و الحجر الرملي لتكوين "عسل" ذات السعه القليلة إلي متوسطة Low to middle amplitude . بالاضافه إلي ذلك تم عمل تحليل كميQuantitative analysis متكامل لتكويني "عسل" و "هواره" باستخدام تسجيلات الآبار و ذلك لإلقاء الضوء علي الجهد الهيدروكربونية لكل منهما. وقد أظهر التحليل الكمي احتواء تكوين "عسل علي تشبعات جيده من الهيدروكربونات تصل إلي أكثر من 90%. كما أوضح أن الخواص البتروفيزيقية لهذا الخزان جيده جده و خاصة في الأجزاء الجنوبية من منطقه الدراسة حيث تتراوح المسامية الفعالةEffective porosity ما بين 9% و 13% و التشبع بالزيت إلي أكثر من 85%، في حين يتضاءل حجم الطفلةShale volume إلي اقل من 5%. و من ناحية أخري اعتبرت صخور الطفل و المارل الخاصة بتكوين "هواره" و الجزء العلوي من تكوين "عسل" نطاقات مشبعه كاملا بالماء Wet zones. تم تطبيق نموذج متكاملIntegrated model يجمع ما بين الخواص السيزمية و البتروفيزيقية و ذلك لفهم طبيعة و خواص التكوينين قيد الدراسة بصوره أفضل. و في هذا الصدد تم إنشاء العديد من العلاقات بين السرعة و الممانعة السيزمية و المسامية الصخرية من ناحية، و بين السرعة والمكونات الصخرية و المحتوي من السوائل من جهة أخري. بصفه عامة أكدت هذه الدراسة علي الخواص الهيدروكربونية المميزه لنطاق الحجر الرملي الخاص بتكوين "عسل" و خاصة في الأجزاء الجنوبية من منطقه الدراسة، كما أثبتت أن تطبيق النموذج المتكامل الذي يجمع ما بين الخواص السيزمية والاخري البتروفيزيقية المشتقة من تسجيلات الآبار قد أدي إلي تحسين تقييم التكوينات المدروسة بدرجه كبيره، فضلا عن تحديد مكوناتهما الصخرية بصوره أوضح، بالاضافه إلي فصلهم الدقيق عن رواسب الميوسين التي تعلوهم.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div

Field is one of the most prolific offshore oil fields in the Gulf of Suez of Egypt. It consists of a number of marine platforms and produces oil from different reservoirs of different geological ages from the Lower Cretaceous to the Miocene. The aim of this study was to enhance a seismic-log evaluational procedure to evaluate the Miocene-aged Asl and Hawara Formations which encounter the main hydrocarbon and source rock potentials in the area North of October Oil Field. The well logging data, the borehole seismic data, and the velocity surveys are all used in this study. A number of synthetic seismograms are constructed and interpreted together with the deduced seismic impedance and reflection coefficient data for many wells in the study area. In addition, a comprehensive velocity analysis is performed using the seismic times and the computed average and interval velocities. These seismic-derived parameters are primarily used in recognizing and locating precisely the marl and sand sections of Asl Formation which show low to middle amplitudes. Furthermore, a quantitative well logging analysis is carried out over Asl and Hawara Formations to shed light over their hydrocarbon potentiality. Good oil saturation is exhibited by the Asl sand section which reaches to more than 90% in the southern parts of the study area. The petrophysical characters of this sand are very good in terms of good effective porosity (9% to13%), low shale volume (V sh S h \u003e 85%). The sections of the Asl marl and the Hawara shale on the other hand are considered completely wet. An integrated model making use of the seismic- and log-derived properties is applied over the two studied formations for better understanding the reservoir of interest. Many relations are constructed between velocity, seismic impedance, and the rock pore spaces on one hand and between the velocity, lithology, and fluid content on the other hand. This study revealed that the sand section attains very good oil-bearing potentiality in the study area and proved that the application of an integrated model of the log- and seismic-derived properties led to an enhanced evaluation of the Asl and Hawara Formations, good discrimination between their lithological components besides precise differentiation from the overlying Middle to Late Miocene sections. يعد حقل أكتوبر للزيت أحد أهم حقول البترول البحرية Off-shore المنتجة للزيت في خليج السويس بمصر، فهو يتكون من مجموعه من الأرصفة البحريةPlatforms و ينتج من عده خزانات ذات عصور جيولوجية مختلفة تتراوح من الطباشيري السفلي إلي الميوسين. تهدف هذه الدراسة إلي تطبيق نموذج تقييمي يعتمد علي خواص مشتقه من البيانات السيزمية و تسجيلات الآبار و ذلك لتقييم تكويني \"عسل\" و \"هواره\" ذا العصر الميوسيني، حيث يحوي هذان التكوينان علي الجهود الهيدروكربونيةHydrocarbon Potentiality و المصدرية الرئيسية للزيت في منطقه شمال حقل أكتوبر. استخدم في هذه الدراسة العديد من تسجيلات الآبار بالإضافة إلي البيانات السيزمية البئرية و بيانات تسجيلات السرعة. كما تم إنشاء و تفسير مجموعه من السيزموجرامات التخليقية Synthetic seismograms مع كل من الممانعة الصوتية و معامل الانعكاس للعديد من الآبار في منطقه الدراسة. بالاضافه إلي هذا تم عمل تحليل كمي للسرعة باستخدام الزمن السيزمي و السرعات المتوسطة و الفترية المقاسة. هذا وقد استخدمت المعاملات المشتقة من البيانات السيزمية بصفه أساسيه و بدقه في تعيين و تحديد نطاقات المارل و الحجر الرملي لتكوين \"عسل\" ذات السعه القليلة إلي متوسطة Low to middle amplitude . بالاضافه إلي ذلك تم عمل تحليل كميQuantitative analysis متكامل لتكويني \"عسل\" و \"هواره\" باستخدام تسجيلات الآبار و ذلك لإلقاء الضوء علي الجهد الهيدروكربونية لكل منهما. وقد أظهر التحليل الكمي احتواء تكوين \"عسل علي تشبعات جيده من الهيدروكربونات تصل إلي أكثر من 90%. كما أوضح أن الخواص البتروفيزيقية لهذا الخزان جيده جده و خاصة في الأجزاء الجنوبية من منطقه الدراسة حيث تتراوح المسامية الفعالةEffective porosity ما بين 9% و 13% و التشبع بالزيت إلي أكثر من 85%، في حين يتضاءل حجم الطفلةShale volume إلي اقل من 5%. و من ناحية أخري اعتبرت صخور الطفل و المارل الخاصة بتكوين \"هواره\" و الجزء العلوي من تكوين \"عسل\" نطاقات مشبعه كاملا بالماء Wet zones. تم تطبيق نموذج متكاملIntegrated model يجمع ما بين الخواص السيزمية و البتروفيزيقية و ذلك لفهم طبيعة و خواص التكوينين قيد الدراسة بصوره أفضل. و في هذا الصدد تم إنشاء العديد من العلاقات بين السرعة و الممانعة السيزمية و المسامية الصخرية من ناحية، و بين السرعة والمكونات الصخرية و المحتوي من السوائل من جهة أخري. بصفه عامة أكدت هذه الدراسة علي الخواص الهيدروكربونية المميزه لنطاق الحجر الرملي الخاص بتكوين \"عسل\" و خاصة في الأجزاء الجنوبية من منطقه الدراسة، كما أثبتت أن تطبيق النموذج المتكامل الذي يجمع ما بين الخواص السيزمية والاخري البتروفيزيقية المشتقة من تسجيلات الآبار قد أدي إلي تحسين تقييم التكوينات المدروسة بدرجه كبيره، فضلا عن تحديد مكوناتهما الصخرية بصوره أوضح، بالاضافه إلي فصلهم الدقيق عن رواسب الميوسين التي تعلوهم.","downloadable_attachments":[{"id":48052433,"asset_id":8572217,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":17690938,"first_name":"Aref","last_name":"Lashin","domain_name":"king-saud","page_name":"ArefLashin","display_name":"Aref Lashin","profile_url":"https://king-saud.academia.edu/ArefLashin?f_ri=77500","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":406,"name":"Geology","url":"https://www.academia.edu/Documents/in/Geology?f_ri=77500","nofollow":true},{"id":8910,"name":"Evaluation","url":"https://www.academia.edu/Documents/in/Evaluation?f_ri=77500","nofollow":true},{"id":77500,"name":"Late Miocene","url":"https://www.academia.edu/Documents/in/Late_Miocene?f_ri=77500","nofollow":true},{"id":302482,"name":"Lower cretaceous","url":"https://www.academia.edu/Documents/in/Lower_cretaceous?f_ri=77500","nofollow":true},{"id":360593,"name":"Logging","url":"https://www.academia.edu/Documents/in/Logging?f_ri=77500"},{"id":675861,"name":"Log analysis","url":"https://www.academia.edu/Documents/in/Log_analysis?f_ri=77500"},{"id":959838,"name":"Arabian Journal of Geosciences","url":"https://www.academia.edu/Documents/in/Arabian_Journal_of_Geosciences?f_ri=77500"},{"id":1553474,"name":"Reflection Coefficient","url":"https://www.academia.edu/Documents/in/Reflection_Coefficient?f_ri=77500"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_25646019" data-work_id="25646019" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/25646019/Khoratpithecus_piriyai_a_Late_Miocene_hominoid_of_Thailand">Khoratpithecus piriyai, a Late Miocene hominoid of Thailand</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">A Khoratpithecus piriyai lower jaw corresponds to a well-preserved Late Miocene hominoid fossil from northeastern Thailand.

Its morphology and internal structure, using a microcomputed tomography scan, are described and compared to those of other known Miocene hominoids. It originated from fluviatile sand and gravel deposits of a large river, and was associated with many fossil tree trunks, wood fragments, and large vertebrate remains. A biochronological analysis by using associated mammal fauna gives an estimated geological age between 9-6 Ma. The flora indicates the occurrence of a riverine tropical forest and wide areas of grassland. K. piriyai displays many original characters, such as the great breadth of its anterior dentition, suggesting large incisors, large lower M3, a canine with a flat lingual wall, and symphysis structure. Several of its morphological derived characters are shared with the orangutan, indicating sister-group relationship with that extant ape. This relationship is additionally strongly supported by the absence of anterior digastric muscle scars. These shared derived characters are not present in Sivapithecus, Ankarapithecus, and Lufengpithecus, which are therefore considered more distant relatives to the orangutan than Khoratpithecus. The Middle Miocene K. chiangmuanensis is older, displays more primitive dental characters, and shares several dental characters with the Late Miocene form. It is therefore interpreted as its probable ancestor. But its less enlarged M3 and more wrinkled enamel may suggest an even closer phylogenetic position to orangutan ancestors, which cannot yet be supported because of the incomplete fossil record. Thus Khoratpithecus represents a new lineage of Southeast Asian hominoids, closely related to extant great ape ancestors.

Vermetid reefs are known from the Badenian (Middle Miocene) to present-day and their main importance is related to their use as sea-level indicators, strictly associated to the intertidal or immediate subtidal zone. During their evolution, two different vermetid genera have been recognized as reef-builders: Petaloconchus was the major component of vermetid reefs until the Holocene when, for still unknown reasons, it was almost completely replaced by Dendropoma. In the Mediterranean Basin, Petaloconchus reefs have been frequently found in close association to Late Miocene coral bioconstructions. New finding of Petaloconchus reefs within the slope facies of the Salento Messinian reef complex (southern Italy), together with new data from late Tortonian-early Messinian reefs of Crete (Greece) provide further information on the palaeoecology of these peculiar bioconstructions. Stratigraphical and sedimentological contexts of Salento and Crete vermetid reefs have been described, together with an account of their size, shape and inner structure. Biotic (vermetids, serpulids, bryozoans and coralline algae) and abiotic components (early marine cements and intra-reef sediment) have been identified by microfacies analysis, and their percentage-abundance has been reported. These data allow the description of vermetid reefs from two different depositional settings: along the shelf edge and, for the first time, within the coral reef slope. Shelf-edge and slope Petaloconchus reefs show the same inner structure and composition, but they differ by their shape, by the density of the framework, and by the relative proportion of the associated reef-building organisms (serpulids, bryozoans and coralline algae). Additional information on their palaeobathymetric setting have been acquired from the presence of other reef-building biota (Porites corals and Halimeda green algae) which occur in close proximity to slope vermetid reefs, together with observations on some anatomical feature of Petaloconchus shells. Results clearly indicate for Petaloconchus reefs a palaeobathymetric range spanning from the upper subtidal zone down to 30-50 m of depth. The present study confirms vermetid reefs as important tools for the reconstructions of ancient sea-level, but great attention has to be paid to the identification of the main reef-building vermetid. Actually, while a great number of present-day Dendropoma reefs can be associated to the mean sea-level, Late Miocene vermetid reefs from Salento and Crete indicate for Petaloconchus bioconstructions a wider palaeobathymetric range.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/26461433" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="039d8e1be4ef0578906f79d4794092b6" rel="nofollow" data-download="{"attachment_id":46756651,"asset_id":26461433,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/46756651/download_file?st=MTczODM0NzQ2NCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="35916809" href="https://independent.academia.edu/FrancescaBosellini">Francesca Bosellini</a><script data-card-contents-for-user="35916809" type="text/json">{"id":35916809,"first_name":"Francesca","last_name":"Bosellini","domain_name":"independent","page_name":"FrancescaBosellini","display_name":"Francesca Bosellini","profile_url":"https://independent.academia.edu/FrancescaBosellini?f_ri=77500","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_26461433 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="26461433"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 26461433, container: ".js-paper-rank-work_26461433", });

Middle to upper Miocene carbonate strata in the Las Negras and Nijar areas (southeastern Spain) are 5&150 m thick and display 5&200 m of shelf-to-basin relief over 1-2 km. Detailed studies in those areas document the effects of relative sea-level change on sedimentation, biotic composition, and reef development. We identify three previously unrecognized, regionally correlatable depositional sequences (DS1, DS2, DS3) that occur between the underlying basement and the overlying Terminal Carbonate Complex. The lower depositional sequences (DSl, DS2) are mostly normal marine shelf (ramp) carbonates deposited on the flanks of basement highs. The basal part of DS2 locally contains some megabreccia reef blocks composed of Tarbellasfraea and Porites. These blocks are the first evidence of reef growth in the area and represent a previously unrecognized period of reef development prior to the fringing reef development. The reef blocks probably formed as upslope patch reefs that were eroded and transported to distal slope locations. The upper sequence (DS3) is characterized by clinoform strata of a Porites-dominated fringing reef complex that prograded basinward in a downstepping style with successively younger reefs forming in a topographically lower and more basinward position as a result of a net sea-level drop.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/11816440" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="5820671ca5097c27a60e46a4d9a9e333" rel="nofollow" data-download="{"attachment_id":46508653,"asset_id":11816440,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/46508653/download_file?st=MTczODM0NzQ2NCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="29132931" href="https://kansas.academia.edu/EvanFranseen">Evan Franseen</a><script data-card-contents-for-user="29132931" type="text/json">{"id":29132931,"first_name":"Evan","last_name":"Franseen","domain_name":"kansas","page_name":"EvanFranseen","display_name":"Evan Franseen","profile_url":"https://kansas.academia.edu/EvanFranseen?f_ri=77500","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_11816440 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="11816440"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 11816440, container: ".js-paper-rank-work_11816440", });

Middle to upper Miocene carbonate strata in the Las Negras and Nijar areas (southeastern Spain) are 5\u0026150 m thick and display 5\u0026200 m of shelf-to-basin relief over 1-2 km. Detailed studies in those areas document the effects of relative sea-level change on sedimentation, biotic composition, and reef development. We identify three previously unrecognized, regionally correlatable depositional sequences (DS1, DS2, DS3) that occur between the underlying basement and the overlying Terminal Carbonate Complex. The lower depositional sequences (DSl, DS2) are mostly normal marine shelf (ramp) carbonates deposited on the flanks of basement highs. The basal part of DS2 locally contains some megabreccia reef blocks composed of Tarbellasfraea and Porites. These blocks are the first evidence of reef growth in the area and represent a previously unrecognized period of reef development prior to the fringing reef development. The reef blocks probably formed as upslope patch reefs that were eroded and transported to distal slope locations. The upper sequence (DS3) is characterized by clinoform strata of a Porites-dominated fringing reef complex that prograded basinward in a downstepping style with successively younger reefs forming in a topographically lower and more basinward position as a result of a net sea-level drop.","downloadable_attachments":[{"id":46508653,"asset_id":11816440,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":29132931,"first_name":"Evan","last_name":"Franseen","domain_name":"kansas","page_name":"EvanFranseen","display_name":"Evan Franseen","profile_url":"https://kansas.academia.edu/EvanFranseen?f_ri=77500","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":406,"name":"Geology","url":"https://www.academia.edu/Documents/in/Geology?f_ri=77500","nofollow":true},{"id":420,"name":"Sedimentology","url":"https://www.academia.edu/Documents/in/Sedimentology?f_ri=77500","nofollow":true},{"id":77500,"name":"Late Miocene","url":"https://www.academia.edu/Documents/in/Late_Miocene?f_ri=77500","nofollow":true}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_24211130" data-work_id="24211130" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/24211130/Role_of_climate_in_partial_drowning_of_the_Queensland_Plateau_carbonate_platform_northeastern_Australia_">Role of climate in partial drowning of the Queensland Plateau carbonate platform (northeastern Australia)</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Ocean Drilling Program Leg 133 core data, samples, and geophysical data (logs and seismics) were analyzed to document late Miocene--early Pliocene partial drowning of the Queensland Plateau carbonate platform off Northeast Australia.

The modern plateau consists of a mosaic of pinnacle reefs and larger (10 × 50 km) reefs representing relicts of early to middle Miocene buildups. Late Miocene-early Pliocene floatstones, packstones, and mudstones, rich in the larger benthic foraminifers Lepidocyclina and Cycloclypeus, drilled in a transect of sites across the drowned margin of a middle Miocene buildup show that the late Pliocene partial drowning of the platform was preceded by 4 Myr of neritic carbonate deposition without any reefs. The carbonate factory was unable to aggrade to sea level during this period as indicated by the lack of any shallowing trend in the succession. Monitoring of the Miocene to Recent neritic shedding pattern on the windward and leeward side of a pinnacle reef on the Queensland Plateau supports this interpretation. Shedding on the leeward side of the reef, which records periods of active reef growth, played a minor role during the late Miocene, increased during the Pliocene, and reached very high values during the late Pliocene and Pleistocene. Shedding on the windward side of the reef, which was active during lowstands of relative sea level, occurred during the late middle-early late Miocene and during the Pliocene--Quaternary. The data presented here, when combined with paleoceanographic data points to low surface water temperatures (17°-19°C) as a major factor which suppressed reef growth during the late Miocene-early Pliocene period.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/24211130" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="f8b7204b37ee82d4d21753d3d358a898" rel="nofollow" data-download="{"attachment_id":44542020,"asset_id":24211130,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/44542020/download_file?st=MTczODM0NzQ2NSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="32876014" href="https://edinburgh.academia.edu/DickKroon">Dick Kroon</a><script data-card-contents-for-user="32876014" type="text/json">{"id":32876014,"first_name":"Dick","last_name":"Kroon","domain_name":"edinburgh","page_name":"DickKroon","display_name":"Dick Kroon","profile_url":"https://edinburgh.academia.edu/DickKroon?f_ri=77500","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_24211130 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="24211130"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 24211130, container: ".js-paper-rank-work_24211130", });

Majorca has a basin and range physiography mainly resulting from Late Neogene extension. The basins and ranges strike NE-SW. The structure of the ranges consists of thrust faults and associated folds involving Mesozoic series. Paleogene series are also involved in the compressional structures located in the southeast, whereas a stratigraphic hiatus embracing Late Cretaceous and Paleogene is present in the rest of the island. The age of syncompressive rocks and sediments is Chattian to Aquitanian in the SE Llevant Ranges, Aquitanian to Burdigalian in the Central Ranges and Burdigalian to Langhian in the NW Tramuntana Range. Thus compressive deformation progressed from southeast to northwest. The thrust fault hangingwall displacement is to the northwest and shortening is large (44%). Seismic reflection sections reveal the presence of compressive structures in the substratum of the basins.

Majorca has a basin and range physiography mainly resulting from Late Neogene extension. The basins and ranges strike NE-SW. The structure of the ranges consists of thrust faults and associated folds involving Mesozoic series. Paleogene series are also involved in the compressional structures located in the southeast, whereas a stratigraphic hiatus embracing Late Cretaceous and Paleogene is present in the rest of the island. The age of syncompressive rocks and sediments is Chattian to Aquitanian in the SE Llevant Ranges, Aquitanian to Burdigalian in the Central Ranges and Burdigalian to Langhian in the NW Tramuntana Range. Thus compressive deformation progressed from southeast to northwest. The thrust fault hangingwall displacement is to the northwest and shortening is large (44%). Seismic reflection sections reveal the presence of compressive structures in the substratum of the basins. Moreover, normal faults due to WNW-ESE extension occurred during the Serravallian and Tortonian, producing additional subsidence in the basins. Minor compression could have occurred since the onset of the Pleistocene. Majorca was shortened when the extensional basins surrounding the island originated. Available models for the origin and evolution of extensional basins of the Western Mediterranean do not consider the structure observed in Majorca.","downloadable_attachments":[{"id":46516352,"asset_id":26194045,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":14226262,"first_name":"Jordi","last_name":"Gimenez","domain_name":"uib-es","page_name":"JordiGimenez","display_name":"Jordi Gimenez","profile_url":"https://uib-es.academia.edu/JordiGimenez?f_ri=77500","photo":"https://0.academia-photos.com/14226262/32646301/29425638/s65_jordi.gimenez.jpg"}],"research_interests":[{"id":406,"name":"Geology","url":"https://www.academia.edu/Documents/in/Geology?f_ri=77500","nofollow":true},{"id":407,"name":"Geochemistry","url":"https://www.academia.edu/Documents/in/Geochemistry?f_ri=77500","nofollow":true},{"id":409,"name":"Geophysics","url":"https://www.academia.edu/Documents/in/Geophysics?f_ri=77500","nofollow":true},{"id":44126,"name":"Tectonophysics","url":"https://www.academia.edu/Documents/in/Tectonophysics?f_ri=77500","nofollow":true},{"id":77500,"name":"Late Miocene","url":"https://www.academia.edu/Documents/in/Late_Miocene?f_ri=77500"},{"id":148652,"name":"Late Cretaceous","url":"https://www.academia.edu/Documents/in/Late_Cretaceous?f_ri=77500"},{"id":551042,"name":"Basin and Range","url":"https://www.academia.edu/Documents/in/Basin_and_Range?f_ri=77500"},{"id":716370,"name":"Seismic reflection","url":"https://www.academia.edu/Documents/in/Seismic_reflection?f_ri=77500"},{"id":1272997,"name":"Western Mediterranean","url":"https://www.academia.edu/Documents/in/Western_Mediterranean?f_ri=77500"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_14215822 coauthored" data-work_id="14215822" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/14215822/New_material_of_the_earliest_hominid_from_the_Upper_Miocene_of_Chad">New material of the earliest hominid from the Upper Miocene of Chad</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Discoveries in Chad by the Mission Paléoanthropologique Franco-Tchadienne have substantially changed our understanding of early human evolution in Africa.

This study presents major and trace element geochemistry, as well as radiogenic isotope (Pb, Sr) signatures, of continental arc magmatic rocks of Ecuador of Eocene to Late Miocene (~50–9 Ma, ELM) and Late Miocene to Recent (~8–0 Ma, LMR) ages. The most primitive ELM and LMR rocks analyzed consistently display similar trace element and isotopic signatures suggesting a common origin, most likely an enriched MORB-type mantle. In contrast, major and trace element geochemistry, as well as radiogenic isotope systematics of the whole sets of ELM and LMR samples, indicate strikingly different evolutions between ELM and LMR rocks. The ELM rocks have consistently low Sr/Y, increasing Rb/Sr, and decreasing Eu/Gd with SiO2, suggesting an evolution through plagioclase-dominated fractional crystallization at shallow crustal levels (SiO2. We explain the adakite-type geochemistry of LMR rocks, rather than by slab melting, by a model in which mantle-derived melts partially melt and assimilate residual garnet-bearing mafic lithologies at deeper levels than those of plagioclase stability (i.e., >20 km), and most likely at sub-crustal levels (>40–50 km). The change in geochemical signatures of Tertiary magmatic rocks of Ecuador from the ELM- to the LMR-type coincides chronologically with the transition from a transpressional to a compressional regime that occurred at ~9 Ma and has been attributed by other investigations to the onset of subduction of the aseismic Carnegie ridge.

This study presents major and trace element geochemistry, as well as radiogenic isotope (Pb, Sr) signatures, of continental arc magmatic rocks of Ecuador of Eocene to Late Miocene (~50–9 Ma, ELM) and Late Miocene to Recent (~8–0 Ma, LMR) ages. The most primitive ELM and LMR rocks analyzed consistently display similar trace element and isotopic signatures suggesting a common origin, most likely an enriched MORB-type mantle. In contrast, major and trace element geochemistry, as well as radiogenic isotope systematics of the whole sets of ELM and LMR samples, indicate strikingly different evolutions between ELM and LMR rocks. The ELM rocks have consistently low Sr/Y, increasing Rb/Sr, and decreasing Eu/Gd with SiO2, suggesting an evolution through plagioclase-dominated fractional crystallization at shallow crustal levels (SiO2. We explain the adakite-type geochemistry of LMR rocks, rather than by slab melting, by a model in which mantle-derived melts partially melt and assimilate residual garnet-bearing mafic lithologies at deeper levels than those of plagioclase stability (i.e., \u003e20 km), and most likely at sub-crustal levels (\u003e40–50 km). The change in geochemical signatures of Tertiary magmatic rocks of Ecuador from the ELM- to the LMR-type coincides chronologically with the transition from a transpressional to a compressional regime that occurred at ~9 Ma and has been attributed by other investigations to the onset of subduction of the aseismic Carnegie ridge.
