Outcrops of the Cajamarca Complex sequence were studied in Rio Claro and Abejorral municipalities of Colombia. The rocks area metapelite samples which were analyzed by a petrographic microscopy, scanning electron microscope (SEM) and geochemical data using major and trace elements. This study focuses on discussing the tectonic implications by the analysis of tectonic discrimination diagrams and the P-T metamorphic conditions calculated in the THERMOCALC software. Bulk geochemistry of metapelites shows an inverse relation to the atomic number in rare earth elements (REE) normalized to chondrite. In addition, the N-MORB analysis shows a depleting of the high-field strength elements (HFSEs) as well as an enrichment on the large-ion Lithophile Elements (LILE). The samples are mainly formed by garnet, amphibole, plagioclase, muscovite, epidote, chlorite and biotite, with rutile, ilmenite, titanite, apatite as accessory phases. The P-T conditions yield a pressure of 8.4 ±3.4 kbar and a temperature of 629 ±83℃. These represent a metamorphic gradient of medium to high pressure and medium temperature metamorphism indicating amphibolite facies conditions, corresponding to Barrovian-type metamorphism. This type of regional metamorphism led toward a depth approximately of 27 km. The tectonic implications across the Colombian Central Cordillera in the present work suggest rifted continental margins developed on continental crust at the edges of continent triggered a oceanic sedimentary basins under a compressive regime. These data suggest that the Jurassic collision previously reported to the south could be extrapolated more to the north in the Cajamarca Complex (Central Cordillera).</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/43950682" 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="ead2b265477afe3bbee761acd4c710cf" rel="nofollow" data-download="{"attachment_id":64276325,"asset_id":43950682,"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/64276325/download_file?st=MTczMjQ1MTg1Myw4LjIyMi4yMDguMTQ2&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="148805541" href="https://independent.academia.edu/NatalyPulidoFernandez">Nataly Pulido Fernandez</a><script data-card-contents-for-user="148805541" type="text/json">{"id":148805541,"first_name":"Nataly","last_name":"Pulido Fernandez","domain_name":"independent","page_name":"NatalyPulidoFernandez","display_name":"Nataly Pulido Fernandez","profile_url":"https://independent.academia.edu/NatalyPulidoFernandez?f_ri=2635","photo":"https://0.academia-photos.com/148805541/44104824/36110071/s65_nataly.pulido_fernandez.jpg"}</script></span></span></li><li class="js-paper-rank-work_43950682 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="43950682"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 43950682, container: ".js-paper-rank-work_43950682", });

These data suggest that the Jurassic collision previously reported to the south could be extrapolated more to the north in the Cajamarca Complex (Central Cordillera).","downloadable_attachments":[{"id":64276325,"asset_id":43950682,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":148805541,"first_name":"Nataly","last_name":"Pulido Fernandez","domain_name":"independent","page_name":"NatalyPulidoFernandez","display_name":"Nataly Pulido Fernandez","profile_url":"https://independent.academia.edu/NatalyPulidoFernandez?f_ri=2635","photo":"https://0.academia-photos.com/148805541/44104824/36110071/s65_nataly.pulido_fernandez.jpg"}],"research_interests":[{"id":2635,"name":"Metamorphic Petrology","url":"https://www.academia.edu/Documents/in/Metamorphic_Petrology?f_ri=2635","nofollow":false}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_35070078" data-work_id="35070078" 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/35070078/%D0%A2%D0%B5%D0%BA%D1%81%D1%82">Текст</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Rare minerals, chloriane amphiboles and chloriane biotites were discovered in rocks of Palaeoproterozoic (Jatulian) traps of Karelia: in gabbro-dolerites of layered Kojkarsko-Svjatnavolok sill and in coarse-grained albitic (“karjalitic”)... <a class="more_link u-tcGrayDark u-linkUnstyled" data-container=".work_35070078" data-show=".complete" data-hide=".summarized" data-more-link-behavior="true" href="#">more</a></div><div class="complete hidden">Rare minerals, chloriane amphiboles and chloriane biotites were discovered in rocks of  Palaeoproterozoic (Jatulian) traps of Karelia: in gabbro-dolerites of layered Kojkarsko-Svjatnavolok sill and in coarse-grained albitic (“karjalitic”) enclave in basaltic flow, which is exposed in village Girvas.

Zafarghand index and Kahang deposit of porphyry copper-molybdenum located in Isfahan province, center of Iran using Satellite data interpretations were discovered in the years of 2010 and 2003, respectively. Geological studies have indicated the presence of argillic and propylitic alteration halos associated with porphyry copper systems. The 250 rock samples were systematically collected at a sampling distance of 100 m and in the center of the porphyry system by a distance o f 50 m in Zafarghand. Also, 377 samples of lithogeochemicals (185 rock samples and 192 soil samples) were extracted systematically from Kahang deposit. The study of geochemical data of rock and soil samples showed similarity of these two types of mineralization with other mineralization of porphyry copper-molybdenum elsewhere in the world. Finally, the comparison of geochemical anomalies copper with rock units and alteration zones showed that atmospheric waters had washed out the copper in some of these zones and probably the supergene zone was formed in depth as porphyry copper-molybdenum deposit.</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/44557405" 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="3e01595d5da12200c6eb2a854059eabc" rel="nofollow" data-download="{"attachment_id":65009324,"asset_id":44557405,"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/65009324/download_file?st=MTczMjQ1MTg1Myw4LjIyMi4yMDguMTQ2&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="24006386" href="https://aud.academia.edu/KavehOstadAliAskari">Kaveh Ostad-Ali-Askari</a><script data-card-contents-for-user="24006386" type="text/json">{"id":24006386,"first_name":"Kaveh","last_name":"Ostad-Ali-Askari","domain_name":"aud","page_name":"KavehOstadAliAskari","display_name":"Kaveh Ostad-Ali-Askari","profile_url":"https://aud.academia.edu/KavehOstadAliAskari?f_ri=2635","photo":"https://0.academia-photos.com/24006386/9871597/162121984/s65_kaveh.ostad-ali-askari.jpg"}</script></span></span></li><li class="js-paper-rank-work_44557405 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="44557405"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 44557405, container: ".js-paper-rank-work_44557405", });

The thermal structure of subduction zones is a key to dehydration of the subducting crust at different depths. Oceanic subduction zones show a large variation in the geotherm, but seismicity and arc volcanism are only prominent in cold subduction zones where geothermal gradients are low. In contrast, continental subduction zones have low geothermal gradients, resulting in metamorphism in cold subduction zones and the absence of arc volcanism during subduction. In very cold subduction zone where the geothermal gradient is very low (5C/km), lawsonite may carry water into great depths of 300 km. In the hot subduction zone where the geothermal gradient is high (>25C/km), the subducting crust dehydrates significantly at shallow depths and may partially melt at depths of <80 km to form felsic melts, into which water is highly dissolved. In this case, only a minor amount of water can be transported into great depths. A number of intermediate modes are present between these two end-member dehydration modes, making subduction-zone dehydration various. Low-T/low-P hy-drous minerals are not stable in warm subduction zones with increasing subduction depths and thus break down at forearc depths of 60–80 km to release large amounts of water. In contrast, the low-T/low-P hydrous minerals are replaced by low-T/high-P hydrous minerals in cold subduction zones with increasing subduction depths, allowing the water to be transported to subarc depths of 80–160 km. In either case, dehydration reactions not only trigger seismicity in the subducting crust but also cause hydration of the mantle wedge. Nevertheless, there are still minor amounts of water to be transported by ultra-high-pressure hydrous minerals and nominally anhydrous minerals into the deeper mantle. The mantle wedge overlying the subducting slab does not partially melt upon water influx for volcanic arc magmatism, but it is hydrated at first with the lowest temperature at the slab-mantle interface, several hundreds of degree lower than the wet solidus of hydrated peridotites. The hydrated peridotites may undergo partial melting upon heating at a later time. Therefore, the water flux from the subducting crust into the overlying mantle wedge does not trigger the volcanic arc magmatism immediately.</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/21719456" 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="5e0aab6da4a7f0a23fe8d8b9fd26012f" rel="nofollow" data-download="{"attachment_id":42455878,"asset_id":21719456,"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/42455878/download_file?st=MTczMjQ1MTg1Myw4LjIyMi4yMDguMTQ2&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="37340839" href="https://independent.academia.edu/YfZheng">Yong-Fei Zheng</a><script data-card-contents-for-user="37340839" type="text/json">{"id":37340839,"first_name":"Yong-Fei","last_name":"Zheng","domain_name":"independent","page_name":"YfZheng","display_name":"Yong-Fei Zheng","profile_url":"https://independent.academia.edu/YfZheng?f_ri=2635","photo":"https://0.academia-photos.com/37340839/24388481/23305966/s65_yong-fei.zheng.jpg"}</script></span></span><span class="u-displayInlineBlock InlineList-item-text"> and <span class="u-textDecorationUnderline u-clickable InlineList-item-text js-work-more-authors-21719456">+2</span><div class="hidden js-additional-users-21719456"><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://independent.academia.edu/RenXuChen">RenXu Chen</a></span></div><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://independent.academia.edu/ZhengXu12">Zheng Xu</a></span></div></div></span><script>(function(){ var popoverSettings = { el: $('.js-work-more-authors-21719456'), placement: 'bottom', hide_delay: 200, html: true, content: function(){ return $('.js-additional-users-21719456').html();

The thermal structure of subduction zones is a key to dehydration of the subducting crust at different depths. Oceanic subduction zones show a large variation in the geotherm, but seismicity and arc volcanism are only prominent in cold subduction zones where geothermal gradients are low. In contrast, continental subduction zones have low geothermal gradients, resulting in metamorphism in cold subduction zones and the absence of arc volcanism during subduction. In very cold subduction zone where the geothermal gradient is very low (5C/km), lawsonite may carry water into great depths of 300 km. In the hot subduction zone where the geothermal gradient is high (\u003e25C/km), the subducting crust dehydrates significantly at shallow depths and may partially melt at depths of \u003c80 km to form felsic melts, into which water is highly dissolved. In this case, only a minor amount of water can be transported into great depths. A number of intermediate modes are present between these two end-member dehydration modes, making subduction-zone dehydration various. Low-T/low-P hy-drous minerals are not stable in warm subduction zones with increasing subduction depths and thus break down at forearc depths of 60–80 km to release large amounts of water. In contrast, the low-T/low-P hydrous minerals are replaced by low-T/high-P hydrous minerals in cold subduction zones with increasing subduction depths, allowing the water to be transported to subarc depths of 80–160 km. In either case, dehydration reactions not only trigger seismicity in the subducting crust but also cause hydration of the mantle wedge. Nevertheless, there are still minor amounts of water to be transported by ultra-high-pressure hydrous minerals and nominally anhydrous minerals into the deeper mantle. The mantle wedge overlying the subducting slab does not partially melt upon water influx for volcanic arc magmatism, but it is hydrated at first with the lowest temperature at the slab-mantle interface, several hundreds of degree lower than the wet solidus of hydrated peridotites. The hydrated peridotites may undergo partial melting upon heating at a later time. Therefore, the water flux from the subducting crust into the overlying mantle wedge does not trigger the volcanic arc magmatism immediately.","downloadable_attachments":[{"id":42455878,"asset_id":21719456,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":37340839,"first_name":"Yong-Fei","last_name":"Zheng","domain_name":"independent","page_name":"YfZheng","display_name":"Yong-Fei

However, in metamorphic systems the pressure is usually calculated with two different approaches. One pressure calculation is based on petrological phase equilibria and this pressure is often termed thermodynamic pressure. The other calculation is based on continuum mechanics, which provides a mean stress that is commonly used to estimate the thermodynamic pressure. Both thermodynamic pressure calculations can be justified by the accuracy and applicability of the results. Here, we consider systems with low differential stress (<1 kbar) and no irreversible volumetric deformation, and refer to them as conventional systems. We investigate the relationship between mean stress and thermodynamic pressure. We discuss the meaning of thermodynamic pressure and its calculation for irreversible processes such as viscous deformation and heat conduction, which exhibit entropy production. Moreover, it is demonstrated that the mean stress for incompressible viscous deformation is essentially equal to the mean stress for the corresponding viscous deformation with elastic compressibility, if the characteristic time of deformation is five times longer than the Maxwell viscoelastic relaxation time that is equal to the ratio of shear viscosity to bulk modulus. For typical lithospheric rocks, this Maxwell time is smaller than c. 10,000 years. Therefore, numerical simulations of long‐term (>10 kyr) geodynamic processes, employing incompressible deformation, provide mean stress values that are close to the mean‐stress value associated with elastic compressibility. Finally, we show that for conventional systems the mean stress is essentially equal to the thermodynamic pressure. However, mean stress and, hence, thermodynamic pressure can be significantly different from the lithostatic pressure.</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/37381758" 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="235c4006d954672ae487b6a0842253fd" rel="nofollow" data-download="{"attachment_id":57344466,"asset_id":37381758,"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/57344466/download_file?st=MTczMjQ1MTg1Myw4LjIyMi4yMDguMTQ2&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="77293" href="https://uoa.academia.edu/DimitriosKostopoulos">Dimitrios Kostopoulos</a><script data-card-contents-for-user="77293" type="text/json">{"id":77293,"first_name":"Dimitrios","last_name":"Kostopoulos","domain_name":"uoa","page_name":"DimitriosKostopoulos","display_name":"Dimitrios Kostopoulos","profile_url":"https://uoa.academia.edu/DimitriosKostopoulos?f_ri=2635","photo":"https://0.academia-photos.com/77293/21425/19557489/s65_dimitrios.kostopoulos.png"}</script></span></span></li><li class="js-paper-rank-work_37381758 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="37381758"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 37381758, container: ".js-paper-rank-work_37381758", });

carefully reading this chapter, completing the exercises within it, and answering the questions at the end, you should be able to: • Summarize the factors that influence the nature of metamorphic rocks and explain why each one is important. • Describe foliation and explain the mechanisms for its formation in metamorphic rocks. • Classify metamorphic rocks on the basis of their texture and mineral content, and explain the origins of these differences. • Describe the various settings in which metamorphic rocks are formed and the links between plate tectonics and metamorphism. • Summarize the important processes of regional metamorphism, and explain how rocks that were metamorphosed at depths of 10 kilometres or 20 kilometres can now be found on Earth's surface. • Describe the important processes of contact metamorphism and metasomatism, and the key role hydrothermal fluids.","downloadable_attachments":[{"id":62400111,"asset_id":42248472,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":150065460,"first_name":"Ibeh","last_name":"Emeka","domain_name":"mountaintopuniversity","page_name":"IbehEmeka","display_name":"Ibeh

Km land area. The mapped area (longitudes 4 deg 0’ 0’’ E and 4 deg 3’ 30’’ E and latitudes 7 deg 41’ 15’’ N and 7 deg 45’ 00’’ N) is part of the basement complex of Southwestern Nigeria. Quartzite and quartz schists cover seventy percent of this area. Other dominant rock types are migmatite, banded, and granite gneisses (migmatites and gneisses make up 25 %), granite (4 %), and amphibolite (1%) respectively.  The general strike of the rocks in this area is NE-SW. Structures such as quartzofeldspathic veins, ptygmatic folds, fractures (mostly discordant), and faults (normal and dextral types) populate the area. The area bears imprints of the Pan-African orogeny. Also, the geological history of the area suggests that the rocks in the area originated from prograding regional metamorphism of the sedimentary rocks (sandstone and shale) and volcanics (such as basaltic bombs). The presence of numerous healed veins across the major fracture zone in the area suggests the presence of hydrothermal deposits. The gneisses and gneisses are useful as aggregates and aesthetics in the construction industry. With the presence of amphibolite, ores associated with ferromagnesian minerals (chromite, niccolite, and magnetite) may be found under detailed exploration.  <br /><br /><br />Note: The fieldwork was carried out (between July and August 2018) as a course (GEY 781) in the Master's degree program at the Department of Geology, University of Ibadan.</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/43025589" 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="7154d4752266c23843a48519f007c7d4" rel="nofollow" data-download="{"attachment_id":63289099,"asset_id":43025589,"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/63289099/download_file?st=MTczMjQ1MTg1Myw4LjIyMi4yMDguMTQ2&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="50974258" href="https://ui-edu-ng.academia.edu/TimileyinAyomideOlanipekun">Timileyin Ayomide Olanipekun</a><script data-card-contents-for-user="50974258" type="text/json">{"id":50974258,"first_name":"Timileyin Ayomide","last_name":"Olanipekun","domain_name":"ui-edu-ng","page_name":"TimileyinAyomideOlanipekun","display_name":"Timileyin Ayomide Olanipekun","profile_url":"https://ui-edu-ng.academia.edu/TimileyinAyomideOlanipekun?f_ri=2635","photo":"https://0.academia-photos.com/50974258/13499017/14686874/s65_timileyin_ayomide.olanipekun.jpg"}</script></span></span></li><li class="js-paper-rank-work_43025589 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="43025589"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 43025589, container: ".js-paper-rank-work_43025589", });

Batuan metamorf Bayah diduga merupakan bagian dari suatu metamorfisme regional yang terbentuk akibat adanya proses subduksi. Proses metamorfisme pada suatu metamorfisme regional cenderung untuk menghasilkan batuan metamorf dengan derajat metamorfisme yang bervariasi. Kondisi ini disebabkan oleh proses metamorfisme yang berlangsung secara kompleks, karena dapat didominasi oleh perubahan kondisi temperatur, perubahan kondisi tekanan maupun kombinasi keduanya.

Batuan metamorf Bayah diduga merupakan bagian dari suatu metamorfisme regional yang terbentuk akibat adanya proses subduksi. Proses metamorfisme pada suatu metamorfisme regional cenderung untuk menghasilkan batuan metamorf dengan derajat metamorfisme yang bervariasi. Kondisi ini disebabkan oleh proses metamorfisme yang berlangsung secara kompleks, karena dapat didominasi oleh perubahan kondisi temperatur, perubahan kondisi tekanan maupun kombinasi keduanya. Hasil penelitian sendiri menunjukkan fasies metamorfisme pada daerah penelitian berkembang mulai fasies sekis hijau, fasies atas sekis hijau, fasies transisi epidot amfibolit dan fasies

In particular, dehydration melting of ultrahigh-pressure (UHP) metamorphic rocks during continental collision provides a petrological link to intracrustal differentiation with respect to the compositional evolution of continental crust. While island arc magmatism represents one end-member of fluid-induced large-scale melting in the mantle wedge during subduction of the oceanic crust, the partial melting of UHP rocks can be viewed as the other end-member of fluid-induced small-scale anatexis during exhumation of the deeply subducted continental crust. This latter type of melting is also triggered by metamorphic dehydration in response to P–T changes during the continental collision. It results in local occurrences of hydrous melts (even supercritical fluids) as felsic veinlets between boundaries of and multiphase solid inclusions in UHP metamorphic minerals as well as local accumulation of veinlet-like felsic leucosomes in foliated UHP metamorphic rocks and metamorphically grown zircons in orogenic peridotites. Thus, very low-degree melts of UHP rocks provide a window into magmatic processes that operated in continental subduction zones. This article presents a review on available results from experimental petrology concerning the possibility of partial melting under conditions of continental subduction-zone metamorphism, and petrological evidence for the occurrence of dehydration-driven in-situ partial melting in natural UHP rocks during the continental collision. Although the deeply subducted continental crust is characterized by a relative lack of aqueous fluids, the partial melting in UHP rocks commonly takes place during decompression exhumation to result in local in-situ occurrences of felsic melts at small scales. This is caused by the local accumulation of aqueous fluids due to the breakdown of hydrous minerals and the exsolution of structural hydroxyl and molecular water from nominally anhydrous minerals in UHP rocks during the exhumation. The dehydration melting of UHP rocks would not only have bearing on the formation of supercritical fluids during subduction-zone metamorphism, but also contribute to element mobility and ultrapotassic magmatism in continental collision orogens. Therefore, the study of dehydration melting and its effects on element transport in UHP slabs, rocks and minerals is a key to chemical geodynamics of continental subduction zones.</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/21910073" 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="5823a9eb29aabe4163f1c8b89a26abc2" rel="nofollow" data-download="{"attachment_id":42643187,"asset_id":21910073,"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/42643187/download_file?st=MTczMjQ1MTg1Myw4LjIyMi4yMDguMTQ2&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="37340839" href="https://independent.academia.edu/YfZheng">Yong-Fei Zheng</a><script data-card-contents-for-user="37340839" type="text/json">{"id":37340839,"first_name":"Yong-Fei","last_name":"Zheng","domain_name":"independent","page_name":"YfZheng","display_name":"Yong-Fei Zheng","profile_url":"https://independent.academia.edu/YfZheng?f_ri=2635","photo":"https://0.academia-photos.com/37340839/24388481/23305966/s65_yong-fei.zheng.jpg"}</script></span></span></li><li class="js-paper-rank-work_21910073 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="21910073"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 21910073, container: ".js-paper-rank-work_21910073", });

In particular, dehydration melting of ultrahigh-pressure (UHP) metamorphic rocks during continental collision provides a petrological link to intracrustal differentiation with respect to the compositional evolution of continental crust. While island arc magmatism represents one end-member of fluid-induced large-scale melting in the mantle wedge during subduction of the oceanic crust, the partial melting of UHP rocks can be viewed as the other end-member of fluid-induced small-scale anatexis during exhumation of the deeply subducted continental crust. This latter type of melting is also triggered by metamorphic dehydration in response to P–T changes during the continental collision. It results in local occurrences of hydrous melts (even supercritical fluids) as felsic veinlets between boundaries of and multiphase solid inclusions in UHP metamorphic minerals as well as local accumulation of veinlet-like felsic leucosomes in foliated UHP metamorphic rocks and metamorphically grown zircons in orogenic peridotites. Thus, very low-degree melts of UHP rocks provide a window into magmatic processes that operated in continental subduction zones. This article presents a review on available results from experimental petrology concerning the possibility of partial melting under conditions of continental subduction-zone metamorphism, and petrological evidence for the occurrence of dehydration-driven in-situ partial melting in natural UHP rocks during the continental collision. Although the deeply subducted continental crust is characterized by a relative lack of aqueous fluids, the partial melting in UHP rocks commonly takes place during decompression exhumation to result in local in-situ occurrences of felsic melts at small scales. This is caused by the local accumulation of aqueous fluids due to the breakdown of hydrous minerals and the exsolution of structural hydroxyl and molecular water from nominally anhydrous minerals in UHP rocks during the exhumation. The dehydration melting of UHP rocks would not only have bearing on the formation of supercritical fluids during subduction-zone metamorphism, but also contribute to element mobility and ultrapotassic magmatism in continental collision orogens. Therefore, the study of dehydration melting and its effects on element transport in UHP slabs, rocks and minerals is a key to chemical geodynamics of continental subduction zones.","downloadable_attachments":[{"id":42643187,"asset_id":21910073,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":37340839,"first_name":"Yong-Fei","last_name":"Zheng","domain_name":"independent","page_name":"YfZheng","display_name":"Yong-Fei

U-Pb dating of igneous zircons from gabbroic rocks yielded a mean age of 563±1 Ma (2), indicating emplacement during the latest Neoproterozoic (Ediacaran). On the other hand, rims of zircons from eclogitic metagabbro gave 535±3 Ma (2s), (early Cambrian), in addition to 558±3 Ma (2s) obtained from the igneous core of zircons. These ages are interpreted as the time of high-P metamorphism and crystallization age of gabbroic protolith, respectively. Given the estimated paleogeographic position of the Anatolide-Tauride Block during the late Neoproterozoic and early Cambrian, this orogenic event can be spatially and temporally related to the northward continuity of 600 – 500 Ma orogenic event (Malagasy / Kuunga orogeny) extending from western margin of India, Madagascar, via Arabia up to northern margin of Gondwana beneath thick Phanerozoic cover series in Arabian Peninsula. Therefore, the high-P evolution of the basement of the Menderes Massif and associated basic intrusions can be interpreted to mark the latest stages of consumption of the basin/oceanic branches and final amalgamation of the Gondwana during the late Neoproterozoic – early Cambrian around the Arabian region.</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/11715792" 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="119cff0c459b6b8c1a2e7ff532efc37d" rel="nofollow" data-download="{"attachment_id":37153861,"asset_id":11715792,"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/37153861/download_file?st=MTczMjQ1MTg1Myw4LjIyMi4yMDguMTQ2&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="3227133" href="https://deu.academia.edu/ErsinKoralay">Ersin Koralay</a><script data-card-contents-for-user="3227133" type="text/json">{"id":3227133,"first_name":"Ersin","last_name":"Koralay","domain_name":"deu","page_name":"ErsinKoralay","display_name":"Ersin Koralay","profile_url":"https://deu.academia.edu/ErsinKoralay?f_ri=2635","photo":"https://0.academia-photos.com/3227133/1062245/1326231/s65_ersin.koralay.jpg"}</script></span></span><span class="u-displayInlineBlock InlineList-item-text"> and <span class="u-textDecorationUnderline u-clickable InlineList-item-text js-work-more-authors-11715792">+1</span><div class="hidden js-additional-users-11715792"><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://istanbultek.academia.edu/G%C3%BCltekinTopuz">Gültekin Topuz</a></span></div></div></span><script>(function(){ var popoverSettings = { el: $('.js-work-more-authors-11715792'), placement: 'bottom', hide_delay: 200, html: true, content: function(){ return $('.js-additional-users-11715792').html();

Here we present geological, petrological and geochemical data, together with zircon U–Pb ages and Lu–Hf isotopes from a suite of metaigneous (TTG-related gneisses, charnockite, metagabbro, mafic granulite) and metasedimentary (quartz mica schist, khondalite, garnet biotite gneiss, kyanite–sillimanite bearing metapelite) rocks from this zone. Geochemical data on the magmatic suite suggests formation through subduction-related arc magmatism, whereas the metasediments represent volcano-sedimentary trench sequences. Phase equilibrium modeling of mafic granulites from the Mercara Shear Zone suggests P–T range of 10–12 kbar at 700 °C to 900 °C. The zircon data yield weighted mean 207 Pb/ 206 Pb ages of 3229 ± 80 Ma for metagabbro, 3168 ± 25 Ma for the charnockite, and 3181 ± 20 Ma for the mafic granulite. Ages ranging from 3248 ± 28 Ma to 3506 ± 26 Ma were obtained from zircons in the kya-nite/sillimanite bearing metapelite, 3335 ± 44 Ma from khondalite, 3135 ± 14 Ma from garnet biotite gneiss, 3145 ± 17 Ma to 3292 ± 57 Ma from quartz mica schist and 3153 ± 15 Ma to 3252 ± 36 from TTG gneiss. The tightly defined ages of 3.1 to 3.2 Ga from igneous zircons in the magmatic suite suggest prominent Mesoarchean convergent margin magmatism. The timing of high grade metamorphism as constrained from metamorphic overgrowths in zircons is ca. 3.0 Ga which might mark the collisional event between the Western Dharwar Craton and the Coorg Block. Hf isotope features suggest magma derivation mostly from juvenile sources and the Lu–Hf model ages indicate that the crust building might have also involved partial recycling of basement rocks as old as ca. 3.8 Ga. Our study defines the Mercara Shear Zone as a terrane boundary, and possible Mesoarchean suture along which the Coorg Block was accreted to the Western Dharwar Craton. The accretion of these continental fragments might have coincided with the birth of the oldest supercontinent " Ur " .</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/30552526" 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="60e3bf52fbf782cf9f1f057ed72441e5" rel="nofollow" data-download="{"attachment_id":50995303,"asset_id":30552526,"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/50995303/download_file?st=MTczMjQ1MTg1Myw4LjIyMi4yMDguMTQ2&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="4453841" href="https://cusat.academia.edu/AMALDEVT">AMALDEV T</a><script data-card-contents-for-user="4453841" type="text/json">{"id":4453841,"first_name":"AMALDEV","last_name":"T","domain_name":"cusat","page_name":"AMALDEVT","display_name":"AMALDEV T","profile_url":"https://cusat.academia.edu/AMALDEVT?f_ri=2635","photo":"https://0.academia-photos.com/4453841/1821476/2248582/s65_amaldev.t.jpg"}</script></span></span><span class="u-displayInlineBlock InlineList-item-text"> and <span class="u-textDecorationUnderline u-clickable InlineList-item-text js-work-more-authors-30552526">+1</span><div class="hidden js-additional-users-30552526"><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://independent.academia.edu/ToshiakiTsunogae">Toshiaki Tsunogae</a></span></div></div></span><script>(function(){ var popoverSettings = { el: $('.js-work-more-authors-30552526'), placement: 'bottom', hide_delay: 200, html: true, content: function(){ return $('.js-additional-users-30552526').html();

Here we present geological, petrological and geochemical data, together with zircon U–Pb ages and Lu–Hf isotopes from a suite of metaigneous (TTG-related gneisses, charnockite, metagabbro, mafic granulite) and metasedimentary (quartz mica schist, khondalite, garnet biotite gneiss, kyanite–sillimanite bearing metapelite) rocks from this zone. Geochemical data on the magmatic suite suggests formation through subduction-related arc magmatism, whereas the metasediments represent volcano-sedimentary trench sequences. Phase equilibrium modeling of mafic granulites from the Mercara Shear Zone suggests P–T range of 10–12 kbar at 700 °C to 900 °C. The zircon data yield weighted mean 207 Pb/ 206 Pb ages of 3229 ± 80 Ma for metagabbro, 3168 ± 25 Ma for the charnockite, and 3181 ± 20 Ma for the mafic granulite. Ages ranging from 3248 ± 28 Ma to 3506 ± 26 Ma were obtained from zircons in the kya-nite/sillimanite bearing metapelite, 3335 ± 44 Ma from khondalite, 3135 ± 14 Ma from garnet biotite gneiss, 3145 ± 17 Ma to 3292 ± 57 Ma from quartz mica schist and 3153 ± 15 Ma to 3252 ± 36 from TTG gneiss. The tightly defined ages of 3.1 to 3.2 Ga from igneous zircons in the magmatic suite suggest prominent Mesoarchean convergent margin magmatism. The timing of high grade metamorphism as constrained from metamorphic overgrowths in zircons is ca. 3.0 Ga which might mark the collisional event between the Western Dharwar Craton and the Coorg Block. Hf isotope features suggest magma derivation mostly from juvenile sources and the Lu–Hf model ages indicate that the crust building might have also involved partial recycling of basement rocks as old as ca. 3.8 Ga. Our study defines the Mercara Shear Zone as a terrane boundary, and possible Mesoarchean suture along which the Coorg Block was accreted to the Western Dharwar Craton. The accretion of these continental fragments might have coincided with the birth of the oldest supercontinent \" Ur \" .","downloadable_attachments":[{"id":50995303,"asset_id":30552526,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":4453841,"first_name":"AMALDEV","last_name":"T","domain_name":"cusat","page_name":"AMALDEVT","display_name":"AMALDEV T","profile_url":"https://cusat.academia.edu/AMALDEVT?f_ri=2635","photo":"https://0.academia-photos.com/4453841/1821476/2248582/s65_amaldev.t.jpg"},{"id":58286382,"first_name":"Toshiaki","last_name":"Tsunogae","domain_name":"independent","page_name":"ToshiakiTsunogae","display_name":"Toshiaki Tsunogae","profile_url":"https://independent.academia.edu/ToshiakiTsunogae?f_ri=2635","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":2635,"name":"Metamorphic Petrology","url":"https://www.academia.edu/Documents/in/Metamorphic_Petrology?f_ri=2635","nofollow":false},{"id":10769,"name":"Tectonics","url":"https://www.academia.edu/Documents/in/Tectonics?f_ri=2635","nofollow":false},{"id":14228,"name":"Geochronology","url":"https://www.academia.edu/Documents/in/Geochronology?f_ri=2635","nofollow":false},{"id":16937,"name":"Petrology and Geochemistry","url":"https://www.academia.edu/Documents/in/Petrology_and_Geochemistry?f_ri=2635","nofollow":false},{"id":531536,"name":"Archean crustal evolution","url":"https://www.academia.edu/Documents/in/Archean_crustal_evolution?f_ri=2635"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_30511395" data-work_id="30511395" 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/30511395/Regional_Al2SiO5_triple_point_metamorphic_rocks_of_northern_New_Mexico_A_field_trip_to_honor_the_career_contributions_of_Lincoln_Hollister_to_petrology_and_tectonics">Regional Al2SiO5 triple-point metamorphic rocks of northern New Mexico: A field trip to honor the career contributions of Lincoln Hollister to petrology and tectonics</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Proterozoic Al2SiO5 " triple-point " metamorphic rocks of north-central New Mexico are examined to honor the career contributions of Lincoln Hollister to petrology and tectonics, and to promote discussion of outstanding problems in... <a class="more_link u-tcGrayDark u-linkUnstyled" data-container=".work_30511395" data-show=".complete" data-hide=".summarized" data-more-link-behavior="true" href="#">more</a></div><div class="complete hidden">Proterozoic Al2SiO5 " triple-point " metamorphic rocks of north-central New Mexico are examined to honor the career contributions of Lincoln Hollister to petrology and tectonics, and to promote discussion of outstanding problems in metamorphic petrology. Hollister's career began with studies of compositional zoning in garnet and staurolite, and interpreting the occurrence of coexisting Al2SiO5 polymorphs in British Columbia. These studies emphasized the kinetic and bulk composition controls of metamorphism. Hollister's interest in the Al2SiO5 polymorphs led to his graduate student, Professor Jeff Grambling's pioneering work that proposed the equilibrium occurrence of coexisting kyanite, sillimanite, and andalusite in the Truchas Peaks, New Mexico. Subsequently, polymetamorphism and the disequilibrium coexistence of kyanite, sillimanite, and andalusite have been proposed as alternate explanations for the occurrence of the polymorphs across the region. Field stops in the Picuris Mountains and Tusas Mountains will visit classic metamorphic rock localities, which are the subject of debate regarding the equilibrium/ disequilibrium nature of the regional " triple-point " metamorphism. The trip will examine Al2SiO5-bearing mineral assemblages to demonstrate the regional distribution of the polymorphs. Stops in the Picuris Mountains will examine andalusite ± cordierite, andalusite ± chloritoid, and kyanite + sillimanite + andalusite–bearing rocks. Field stops in the Tusas Mountains will show kyanite and sillimanite ± garnet–bearing assemblages. Garnet + biotite ± staurolite–bearing rocks are common in both areas and will be examined. Results of garnet, monazite, and zircon geochronology and their bearing on the P-T-t-D paths for the region and the timing of orogenesis will be discussed.</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/30511395" 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="a74103fa287c6891d4ff14986688b60d" rel="nofollow" data-download="{"attachment_id":50958263,"asset_id":30511395,"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/50958263/download_file?st=MTczMjQ1MTg1Myw4LjIyMi4yMDguMTQ2&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="155269" href="https://bucknell.academia.edu/ChristopherDaniel">Christopher Daniel</a><script data-card-contents-for-user="155269" type="text/json">{"id":155269,"first_name":"Christopher","last_name":"Daniel","domain_name":"bucknell","page_name":"ChristopherDaniel","display_name":"Christopher Daniel","profile_url":"https://bucknell.academia.edu/ChristopherDaniel?f_ri=2635","photo":"https://0.academia-photos.com/155269/1083127/1350891/s65_christopher.daniel.jpg"}</script></span></span></li><li class="js-paper-rank-work_30511395 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="30511395"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 30511395, container: ".js-paper-rank-work_30511395", });

With use of basic, often improvised off the shelf equipment, standard petrographic thin sections of rocks, sediments, ceramics, mortars and plasters can be produced and examined. The use of newly-introduced Goren portable microscope enables laboratory-grade examination and recording of such materials during field expeditions. Examples from the field of material analysis in art and archaeology are demonstrated.","downloadable_attachments":[{"id":34775517,"asset_id":8376802,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":204598,"first_name":"Yuval","last_name":"Goren","domain_name":"bgu","page_name":"YuvalGoren","display_name":"Yuval

In the Central Iberian Zone, initial continental thickening (D 1 ; folding and thrusting) was followed by extensional orogenic collapse (D 2) responsible for the exhumation of high-grade rocks coeval to the emplacement of granitoids. This study presents a tectonometamorphic analysis of the Trancoso-Pinhel region (Central Iberian Zone) to explain the processes in place during the transition from an extension-dominated state (D 2) to a compression-dominated one (D 3). We reveal the existence of low-dipping D 2 extensional structures later affected by several pulses of subhorizontal shortening, each of them typified by upright folds and strike-slip shearing (D 3 , D 4 and D 5 , as identified by superimposition of structures). The D 2 Pinhel extensional shear zone separates a low-grade domain from an underlying high-grade domain, and it contributed to the thermal reequilibration of the orogen by facilitating heat advection from lower parts of the crust, crustal thinning, decompression melting, and magma intrusion. Progressive lessening of the gravitational disequilibrium carried out by this D 2 shear zone led to a switch from subhorizontal extension to compression and the eventual cessation and capture of the Pinhel shear zone by strike-slip tectonics during renewed crustal shortening. High-grade domains of the Pinhel shear zone were folded together with low-grade domains to define the current upright folded structure of the Trancoso-Pinhel region , the D 3 Tamames-Marofa-Sátão synform. New dating of syn-orogenic granitoids (SHRIMP U\ \Pb zircon dating) intruding the Pinhel shear zone, together with the already published ages of early extensional fabrics constrain the functioning of this shear zone to ca. 331–311 Ma, with maximum tectonomagmatic activity at ca. 321–317 Ma. The capture and apparent cessation of movement of the Pinhel shear zone occurred at ca. 317– 311 Ma.</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/30551712" 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="b397c4cdc189db626778fd44b464a84a" rel="nofollow" data-download="{"attachment_id":50994715,"asset_id":30551712,"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/50994715/download_file?st=MTczMjQ1MTg1Myw4LjIyMi4yMDguMTQ2&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="491020" href="https://igme-es.academia.edu/RubenDiezFernandez">Ruben Diez Fernandez</a><script data-card-contents-for-user="491020" type="text/json">{"id":491020,"first_name":"Ruben","last_name":"Diez Fernandez","domain_name":"igme-es","page_name":"RubenDiezFernandez","display_name":"Ruben Diez Fernandez","profile_url":"https://igme-es.academia.edu/RubenDiezFernandez?f_ri=2635","photo":"https://0.academia-photos.com/491020/240056/18668447/s65_ruben.diez_fernandez.jpg"}</script></span></span></li><li class="js-paper-rank-work_30551712 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="30551712"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 30551712, container: ".js-paper-rank-work_30551712", });

Petrostructural analysis carried out in the eastern flank of this dome reveals that extensional flow resulted in progressive exhumation of mainland Gondwana, which rested under peri-gondwanan alloch-thonous terranes and a suture zone during maximum crustal thickening. Exhumation proceeded up to upper crust levels (andalusite stability field) along with partial melting of the middle-lower crust and with the generation of granitoid laccoliths during an early extensional stage. Newly-formed lithological and mechanical anisot-ropies, such as the presence of variably-sized sheet-shaped bodies of syn-orogenic granitoids, provided a favorable rheological setting for fold nucleation during the intermediate stages of extension. In extending oro-genic crust, whether recumbent folds occur after significant melt production depends on the lateral/vertical flow ratio, and on the orientation of deforming bodies with regard to kinematic/strain axes. We suggest that subhorizontal extensional flow dominated over vertical flow during the early and intermediate stages of the evolution of the Padrón dome. A component of vertical (diapiric) flow caused progressive tilting of the sheet-like bodies and obliquity respect to strain axes. This resulted in the development of regional-scale folds at the expense of syn-orogenic granitoids, such as in the case of the Portomouro recumbent synform. Extensional ductile flow was oblique to the trend of the orogen during the whole process, and directed to the NNW during the formation of recumbent folds. Non-coaxial shearing favored an (NNW-SSE) elongate shape for the syn-kinematic granitic massifs as well as the subsequent nucleation of recumbent folds. Deformation concentrated along discrete detachments during the late stages of extension.</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/32041793" 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="d037c8be11f5ab8ac601b14323d5e5c1" rel="nofollow" data-download="{"attachment_id":52303815,"asset_id":32041793,"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/52303815/download_file?st=MTczMjQ1MTg1Myw4LjIyMi4yMDguMTQ2&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="491020" href="https://igme-es.academia.edu/RubenDiezFernandez">Ruben Diez Fernandez</a><script data-card-contents-for-user="491020" type="text/json">{"id":491020,"first_name":"Ruben","last_name":"Diez Fernandez","domain_name":"igme-es","page_name":"RubenDiezFernandez","display_name":"Ruben Diez Fernandez","profile_url":"https://igme-es.academia.edu/RubenDiezFernandez?f_ri=2635","photo":"https://0.academia-photos.com/491020/240056/18668447/s65_ruben.diez_fernandez.jpg"}</script></span></span></li><li class="js-paper-rank-work_32041793 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="32041793"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 32041793, container: ".js-paper-rank-work_32041793", });

This suture zone is made of allochthonous terranes and is currently preserved as a tectonically dismembered ensemble. A multi-proxy analysis is applied to the basal allochthonous units of Iberia to test their affinity and potential usage for tracing a suture zone. A comparison of the lithostratigraphy, tectonometamorphic evolution, geochronology, and geochemical characteristics of the Ediacaran series of these units reveals striking affinities.

These Ediacaran series were affected by high-P and low-to medium-T metamorphism (blueschist to eclogite facies) during the Late Devonian (ca. 370 Ma). They occur below allochthonous ophiolitic sequences, and on top of autochthonous or parautochthonous domains lacking of high-P and low-to medium-T Devonian metamorphism, i.e., tectonically sandwiched between lithosphere-scale thrusts. The combination of all these characteristics makes these particular Ediacaran series different from the rest of the terranes of the Iberian Massif. Such singularity could be useful for tracing more occurrences of the same suture zone along the Variscan orogen, particularly in cases where its preservation and recognition may be cryptic.

Textural relationships hint at a cogenetic intrusion of silicate and carbonate liquids that according to antithetic REE profiles segregated at shallow depths (b0.6 GPa) from a parental melt sourced deeper in the mantle. Fenites bear similar REE abundances to mafic rocks but with high Rb-Ba and low Nb-Ta values. SHRIMP II U-Pb analyses of magmatic zircon cores (δ 18 O = 7.21–7.51) from a carbonate-bearing syenitic amphibolite yielded a Permian intrusion age at 278 ± 2 Ma, considerably older than a Cretaceous (118 ± 4 Ma) greenschist overprint obtained from metamorphic zircon rims (δ 18 O = 6.78–7.02). From 300 to 175 Ma the ɛ Nd of the Pelagonian magmatism rose irregularly to more primitive values attesting to a higher increment of asthenosphere-derived melts. In this context, the carbonatite formed within a transtensional regime of an intra-Pangaea dextral transform fault that signalled the forthcoming penetrating breakoff of the su-percontinent, manifested in the Permo-Triassic.</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/36058773" 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="be5d1c58cd124e949c622b16be354070" rel="nofollow" data-download="{"attachment_id":55944285,"asset_id":36058773,"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/55944285/download_file?st=MTczMjQ1MTg1Myw4LjIyMi4yMDguMTQ2&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="77293" href="https://uoa.academia.edu/DimitriosKostopoulos">Dimitrios Kostopoulos</a><script data-card-contents-for-user="77293" type="text/json">{"id":77293,"first_name":"Dimitrios","last_name":"Kostopoulos","domain_name":"uoa","page_name":"DimitriosKostopoulos","display_name":"Dimitrios Kostopoulos","profile_url":"https://uoa.academia.edu/DimitriosKostopoulos?f_ri=2635","photo":"https://0.academia-photos.com/77293/21425/19557489/s65_dimitrios.kostopoulos.png"}</script></span></span><span class="u-displayInlineBlock InlineList-item-text"> and <span class="u-textDecorationUnderline u-clickable InlineList-item-text js-work-more-authors-36058773">+1</span><div class="hidden js-additional-users-36058773"><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://independent.academia.edu/FilippoSchenker">Filippo Luca Schenker</a></span></div></div></span><script>(function(){ var popoverSettings = { el: $('.js-work-more-authors-36058773'), placement: 'bottom', hide_delay: 200, html: true, content: function(){ return $('.js-additional-users-36058773').html();

In this context, the carbonatite formed within a transtensional regime of an intra-Pangaea dextral transform fault that signalled the forthcoming penetrating breakoff of the su-percontinent, manifested in the Permo-Triassic.","downloadable_attachments":[{"id":55944285,"asset_id":36058773,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":77293,"first_name":"Dimitrios","last_name":"Kostopoulos","domain_name":"uoa","page_name":"DimitriosKostopoulos","display_name":"Dimitrios Kostopoulos","profile_url":"https://uoa.academia.edu/DimitriosKostopoulos?f_ri=2635","photo":"https://0.academia-photos.com/77293/21425/19557489/s65_dimitrios.kostopoulos.png"},{"id":61116883,"first_name":"Filippo Luca","last_name":"Schenker","domain_name":"independent","page_name":"FilippoSchenker","display_name":"Filippo Luca Schenker","profile_url":"https://independent.academia.edu/FilippoSchenker?f_ri=2635","photo":"https://0.academia-photos.com/61116883/18728919/18689736/s65_filippo_luca.schenker.jpg"}],"research_interests":[{"id":406,"name":"Geology","url":"https://www.academia.edu/Documents/in/Geology?f_ri=2635","nofollow":false},{"id":407,"name":"Geochemistry","url":"https://www.academia.edu/Documents/in/Geochemistry?f_ri=2635","nofollow":false},{"id":2404,"name":"Petrology","url":"https://www.academia.edu/Documents/in/Petrology?f_ri=2635","nofollow":false},{"id":2635,"name":"Metamorphic Petrology","url":"https://www.academia.edu/Documents/in/Metamorphic_Petrology?f_ri=2635","nofollow":false},{"id":7959,"name":"Stable Isotope Geochemistry","url":"https://www.academia.edu/Documents/in/Stable_Isotope_Geochemistry?f_ri=2635"},{"id":8116,"name":"Trace element Geochemistry","url":"https://www.academia.edu/Documents/in/Trace_element_Geochemistry?f_ri=2635"},{"id":15947,"name":"Geodynamics","url":"https://www.academia.edu/Documents/in/Geodynamics?f_ri=2635"},{"id":15989,"name":"Igneous petrology","url":"https://www.academia.edu/Documents/in/Igneous_petrology?f_ri=2635"},{"id":16937,"name":"Petrology and Geochemistry","url":"https://www.academia.edu/Documents/in/Petrology_and_Geochemistry?f_ri=2635"},{"id":20000,"name":"Radiogenic Isotope Geochemistry","url":"https://www.academia.edu/Documents/in/Radiogenic_Isotope_Geochemistry?f_ri=2635"},{"id":29674,"name":"Isotope Geochemistry","url":"https://www.academia.edu/Documents/in/Isotope_Geochemistry?f_ri=2635"},{"id":48044,"name":"Greece","url":"https://www.academia.edu/Documents/in/Greece?f_ri=2635"},{"id":99318,"name":"Geotectonics and Geodynamics","url":"https://www.academia.edu/Documents/in/Geotectonics_and_Geodynamics?f_ri=2635"},{"id":255222,"name":"Igneous and Metamorphic Petrology","url":"https://www.academia.edu/Documents/in/Igneous_and_Metamorphic_Petrology?f_ri=2635"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_12570495" data-work_id="12570495" 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/12570495/The_Late_Devonian_Variscan_suture_of_the_Iberian_Massif_A_correlation_of_high_pressure_belts_in_NW_and_SW_Iberia">The Late Devonian Variscan suture of the Iberian Massif: A correlation of high-pressure belts in NW and SW Iberia</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Correlation of three high-P and low to intermediate-T belts from NW and SW Iberia allows recognition of a single terrane affected by Late Devonian continental subduction during the Variscan orogeny.

Two major progressive phases of ductile deformation are documented, which are related to distinct episodes of tectonic burial and exhumation of the Pelagonian continental margin, which was facing the Neotethys/Vardar ocean. Review of existing data sets from neighboring regions shows that both deformation phases can be correlated along strike up to the Dinarides. The first phase of tectonic burial and exhumation (D1) is characterized by NW-SE tectonic transport, greenschist facies metamorphism, and Early Cretaceous (~105-135Ma) 40 Ar/ 39 Ar white mica single fusion ages. D1 is correlated with the initial closure of the Vardar ocean by top-to-the-W to NW ophiolite obduction and the underthrusting of the Pelagonian margin below the oceanic upper plate. Underthrusting was followed by exhumation and the deposition of Late Cretaceous-Paleogene sediments. The second phase of burial and exhumation (D2) is characterized by NE-SW tectonic transport, greenschist to blueschist facies metamorphism, and latest Cretaceous-Early Eocene 40 Ar/ 39 Ar white mica ages of S 2 fabrics. Top-to-the-SW shearing is correlated with the tectonic burial of the Pelagonian zone below the Eurasian continent (Rhodopia), while top-to-the-NE shearing is attributed to subsequent extensional exhumation.
