This artwork depicts the vision of Canberra, the then future National Capital, on the shores of Lake George as an Australian Venice, with elaborate architecture, lush vegetation, sail boats and picturesque jetties, boat sheds and promenades. The artist, Charles Coulter, was an architect commissioned by the Lake George Capital Site League, a lobby group for the future National Capital to be built around Lake George, to design a parliament building and city centre around the lake.

These differences allow a very high-resolution study of past sedimentary environments.","impression_tracking_id":null,"owner":{"id":498748,"first_name":"Eva","middle_initials":null,"last_name":"Papp","page_name":"EvaPapp","domain_name":"anu-au","created_at":"2011-06-18T15:04:45.613-07:00","display_name":"Eva Papp","url":"https://anu-au.academia.edu/EvaPapp"},"attachments":[],"research_interests":[],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") if (false) { Aedu.setUpFigureCarousel('profile-work-38027989-figures'); } }); </script> <div class="js-work-strip profile--work_container" data-work-id="34514044"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/34514044/AZ_%C5%90S%C3%89LETNYOMOK_K%C3%96RNYEZETJELZ%C5%90_SZEREPE_A_WEEREEWA_T%C3%93_LAKE_GEORGE_%C3%9AJ_D%C3%89L_WALES_AUSZTR%C3%81LIA_NEGYEDID%C5%90SZAKI_K%C3%89PZ%C5%90DM%C3%89NYEIBEN_Trace_fossils_as_paleo_environmental_indicators_from_the_Quaternary_of_Weereewa_Lake_George_NSW_Australia"><img alt="Research paper thumbnail of AZ ŐSÉLETNYOMOK KÖRNYEZETJELZŐ SZEREPE A WEEREEWA – TÓ (LAKE GEORGE, ÚJ-DÉL-WALES, AUSZTRÁLIA) NEGYEDIDŐSZAKI KÉPZŐDMÉNYEIBEN Trace fossils as paleo-environmental indicators from the Quaternary of Weereewa, (Lake George), NSW, Australia" class="work-thumbnail" src="https://attachments.academia-assets.com/54379174/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/34514044/AZ_%C5%90S%C3%89LETNYOMOK_K%C3%96RNYEZETJELZ%C5%90_SZEREPE_A_WEEREEWA_T%C3%93_LAKE_GEORGE_%C3%9AJ_D%C3%89L_WALES_AUSZTR%C3%81LIA_NEGYEDID%C5%90SZAKI_K%C3%89PZ%C5%90DM%C3%89NYEIBEN_Trace_fossils_as_paleo_environmental_indicators_from_the_Quaternary_of_Weereewa_Lake_George_NSW_Australia">AZ ŐSÉLETNYOMOK KÖRNYEZETJELZŐ SZEREPE A WEEREEWA – TÓ (LAKE GEORGE, ÚJ-DÉL-WALES, AUSZTRÁLIA) NEGYEDIDŐSZAKI KÉPZŐDMÉNYEIBEN Trace fossils as paleo-environmental indicators from the Quaternary of Weereewa, (Lake George), NSW, Australia</a></div><div class="wp-workCard_item wp-workCard--coauthors"><span>by </span><span><a class="" data-click-track="profile-work-strip-authors" href="https://anu-au.academia.edu/EvaPapp">Eva Papp</a> and <a class="" data-click-track="profile-work-strip-authors" href="https://unideb.academia.edu/DavidArpad">David Arpad</a></span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">A Weereewa, melyet a fehér telepesek Lake George névre kereszteltek 1820-ban, egy időszakos tó Ca...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">A Weereewa, melyet a fehér telepesek Lake George névre kereszteltek 1820-ban, egy időszakos tó Canberrától, Ausztrália fővárosától negyven kilométerre északkeletre.

There are multiple aquifers in the catchment, making it difficult to understand the impacts of groundwater extraction and irrigation. Known groundwater mounding from irrigation and decreasing hydraulic heads from groundwater extraction, combined with groundwater salinity represent a significant threat to the future of extraction and irrigation in the CIA. In this study we discovered a previously unmapped branch of a known palaeochannel system within the heavily irrigated CIA, based on radiometrics images. We then used a combination of resistivity geophysics, geological logs, hydrogeology and hydrogeochemistry to understand the subsurface geometry of the palaeochannel and the impacts on groundwater. Four resistivity surveys totalling 2.8 km length and 60 m depth were conducted over the paleochannel, with survey lines run parallel to irrigation channels. The results revealed a broad sandy paleochannel partially filled with clay sediments. The clay-rich regions can act as aquitards that impede downward groundwater flow and contribute to rising water tables and elevated levels of shallow groundwater salinity. The sand-rich parts of the channel can provide pathways for saline water from the shallow aquifers to leak into deeper aquifers. We also found evidence of leakage from bores and irrigation channels. Bore hydrographs show that the aquifers are well connected at depths greater than approximately 50 m, where groundwater is extracted for irrigation, but less well connected at shallower depths, reflecting the sand-rich and clay-rich parts of the channel. The shallow groundwater is saline and becomes fresher with increasing depth. Combined with strong downwards hydraulic gradients, this results in a risk to the water quality in the deeper aquifers, if the saline groundwater is transported into the freshwater aquifers at depth.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="87c09f396e17b01ab060177ba158e3e0" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":35150966,"asset_id":8803757,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/35150966/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="8803757"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="8803757"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 8803757; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=8803757]").text(description); $(".js-view-count[data-work-id=8803757]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 8803757; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='8803757']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "87c09f396e17b01ab060177ba158e3e0" } } $('.js-work-strip[data-work-id=8803757]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":8803757,"title":"Papp, É., Burraston, L. and McPhail, D.C.: Identifying palaeochannels and their influence on groundwater systems in the Lower Murrumbidgee catchment, NSW.","translated_title":"","metadata":{"abstract":"Alluvial plains are often host to major agricultural irrigation areas, such as the Coleambally Irrigation Area (CIA) in the Lower Murrumbidgee Catchment, New South Wales, Australia.

We then used a combination of resistivity geophysics, geological logs, hydrogeology and hydrogeochemistry to understand the subsurface geometry of the palaeochannel and the impacts on groundwater. Four resistivity surveys totalling 2.8 km length and 60 m depth were conducted over the paleochannel, with survey lines run parallel to irrigation channels. The results revealed a broad sandy paleochannel partially filled with clay sediments. The clay-rich regions can act as aquitards that impede downward groundwater flow and contribute to rising water tables and elevated levels of shallow groundwater salinity. The sand-rich parts of the channel can provide pathways for saline water from the shallow aquifers to leak into deeper aquifers. We also found evidence of leakage from bores and irrigation channels. Bore hydrographs show that the aquifers are well connected at depths greater than approximately 50 m, where groundwater is extracted for irrigation, but less well connected at shallower depths, reflecting the sand-rich and clay-rich parts of the channel. The shallow groundwater is saline and becomes fresher with increasing depth. Combined with strong downwards hydraulic gradients, this results in a risk to the water quality in the deeper aquifers, if the saline groundwater is transported into the freshwater aquifers at depth.","more_info":"Pesented at HUNGEO 2014, 22-26 August 2014 Debrecen, Hungary","publication_date":{"day":null,"month":8,"year":2014,"errors":{}},"publication_name":"HUNGEO 2014, pp. 156-167.

The first aim of these seismic surveys was to map in <br />detail the profile of the palaeochannels. The second aim was to <br />establish the regolith stratigraphy within the channels and evaluate the techniques used for acquiring and processing such data. Short receiver spacings, down to one metre, were used in order to achieve satisfactory resolution of the anticipated shallow targets. The short length of the split spread meant that extra effort was required to eliminate noise close to the source. Paradigm Inc. DISCOTM/Focus software allowed interactive tests of processing parameters.

The simple examples\r\ndescribed in this paper provide insight into the developed\r\nmethodology.","impression_tracking_id":null,"owner":{"id":498748,"first_name":"Eva","middle_initials":null,"last_name":"Papp","page_name":"EvaPapp","domain_name":"anu-au","created_at":"2011-06-18T15:04:45.613-07:00","display_name":"Eva Papp","url":"https://anu-au.academia.edu/EvaPapp"},"attachments":[{"id":22549972,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/22549972/thumbnails/1.jpg","file_name":"Papp_Baxter_2002.pdf","download_url":"https://www.academia.edu/attachments/22549972/download_file","bulk_download_file_name":"Papp_E_and_Baxter_R_Factor_analysis_and.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/22549972/Papp_Baxter_2002-libre.pdf?1390867302=\u0026response-content-disposition=attachment%3B+filename%3DPapp_E_and_Baxter_R_Factor_analysis_and.pdf\u0026Expires=1744157148\u0026Signature=CbK-TnA5mijTLLUwPS-ZX5ibuUEFqWhY7WUb8qiWUxcymrpURy7YvZOzSGhBGPceZ4HxmIIVZLHT852UtNRoAiUSIF6CqS7W0OUZSMJCONdDfyHD~bsFhrScpTHn1F7oHTjEPy5v2U9VRyFkQQQaQlB-ktioOtmrWIzoNJq4CVe~JYB9H9jCYRsOk-~yXeTvL~QeIiIGUYJNltkBhhyRmFPZrvgwmluUkHGo7H2qpN1Tj78qIOaU7LLfvz7shEcvFq0P-z~PTUEspGCC4U~9CuNSOmAqL9BqNQ1RPWNCSVnTC4DKCWnyHwJhIMu~xErJg8PLp7UHwaw8KFrps1E0yA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") if (false) { Aedu.setUpFigureCarousel('profile-work-1765277-figures'); } }); </script> <div class="js-work-strip profile--work_container" data-work-id="1765605"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" rel="nofollow" href="https://www.academia.edu/1765605/%C3%89va_Papp_Ground_Penetrating_Radar_survey_of_the_Casey_road"><img alt="Research paper thumbnail of Éva Papp: Ground Penetrating Radar survey of the Casey road.

Compositional data suggest that the iron loss starts at petrologic class 6; at classes 6 and 7 of any chondrite type metallic iron (and maybe FeS) is less than for 1-5.","impression_tracking_id":null,"owner":{"id":498748,"first_name":"Eva","middle_initials":null,"last_name":"Papp","page_name":"EvaPapp","domain_name":"anu-au","created_at":"2011-06-18T15:04:45.613-07:00","display_name":"Eva Papp","url":"https://anu-au.academia.edu/EvaPapp"},"attachments":[{"id":53739900,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/53739900/thumbnails/1.jpg","file_name":"mineralogica_039_087-105.pdf","download_url":"https://www.academia.edu/attachments/53739900/download_file","bulk_download_file_name":"Sz_Berczi_B_Lukacs_A_Holba_A_Kiss_and_E.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/53739900/mineralogica_039_087-105-libre.pdf?1499073204=\u0026response-content-disposition=attachment%3B+filename%3DSz_Berczi_B_Lukacs_A_Holba_A_Kiss_and_E.pdf\u0026Expires=1744157148\u0026Signature=FTlPcd4L2hKbnvbSd9Zn3BGhDY~5PYelrFj0uWEtqd32UzyUh1RSz48utD~jhxVveVGWeO5zy3KzLXBpo5n4qt215dWZsAvcESnu3yzF6FVIL-zLaW-FdwldWqSi7wiuu7nH~AAcABAxHKRbloGM~XkVF~0fsbUemE9s-23ZdlCGc75NYgPrkmL6IzYohNVZwSuT2pFPh90RTy0Sf4BVo7qWBtUG0v-51byQ4wZ71JLuatW00nP09Bl7saPQOkje2xy7khZtsbI0n9O7p153Yl7fWj9uRjiLD-ltECwLPP~ZAXMiYLXmxyMxHlGBkeLeDVFXrFrXN8KuPEi1NemDPg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") if (true) { Aedu.setUpFigureCarousel('profile-work-1767076-figures'); } }); </script> <div class="js-work-strip profile--work_container" data-work-id="1767083"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" rel="nofollow" href="https://www.academia.edu/1767083/B_Luk%C3%A1cs_Sz_B%C3%A9rczi_S_J%C3%B3zsa_Gy_Szakm%C3%A1ny_and_%C3%89_Papp_Thermal_transformations_in_the_meteorite_parent_bodies_II"><img alt="Research paper thumbnail of B.

Regolith logging with a small, easy-to-use geophysical logging system, mounted in a 4WD vehicle. Geophysical well logging offers the opportunity of determining the composition, variability and physical properties of the rocks around the borehole. The actual volume of material sampled in this way varies from technique to technique and with the geological conditions, but it is invariably much larger than is represented by just the borehole. Moreover, depth control with a modern geophysical logging system is often better than a few millimetres. This means that the depth resolution of borehole data, representing the subsurface structure, is generally better than can be obtained even with diamond coring, where core breakage and core loss can be a serious problem, especially in regolith. Modern geophysical logging systems can be easily deployed from 4WD vehicles, using digital, computerised. small svstems. such as the one shown jn Ficure 3.

Note that resistivity logs only work if the downhole probe is below the water table. This can be a limitation for some shallow regolith studies unless water can be added to the borehole to artificially raise the level to the area of interest. Single-point resistivity logging measures the resistivity between a single moving electrode downhole and an earth connection at the surface. Theoretical analysis and practical observation shows however that the bulk of the signal is in fact generated within a small volume surrounding the downhole electrode. Thus for a 5 cm diameter spherical electrode, 90% of the signal is generated within 50 cm of the electrode.

Saline groundwater which is in contact with clay-rich materials often develop charge imbalances (ie. potentials) as a result of fluid flow.

A multidisciplinary research project obtained a good quality 77 metres long sedimentary core from the lake bed during 2015. 17 clay samples from the core have been sent to and analysed in the GEOCHEM labs in Pécs, Hungary, during 2016. Analytical methods included He-pycnometry, physisorption, grain size analysis and electrical resistivity measurements. Plugs with different diameters (1 " , 9 mm) were prepared with manual sampling. Fragments and plugs were dried at 80 °C in a drying oven for 12-14 days before the measurements. The geometric volume of the plugs were measured and calculated before and again after the drying process. He-pycnometry was used to measure the skeletal volume (cm 3) at 25 Celsius in both cases. Skeletal density (g/cm 3), geometric volume (cm 3), bulk density (g/cm 3) and He-porosity (%) were calculated. During physisorption, N2 (77 K) and CO2 (273 K) gas was used to obtain adsorption and desorption isotherms. Nitrogen was used to measure BET surface (m 2 /g), pore size distribution (Barrett-Joyner-Halenda method), fractal dimension (Frenkel-Halsey-Hill method), and pore volume (cm 3 /g). CO2 gas is very suitable for examination of micro-pores (d < 2 nm) (Condon, 2006). In this study we calculated micro-pore volume and surface area using the Dubinin-Radushkevich method. During particle size analysis, we determined average grain size and grain size distribution, using CILAS 1180 LD type laser granulometer. For classification based on grain size, we used the generally accepted nomenclature (Szakmány, 2008) and for classification based on sediment-type we used the Shepard-nomenclature (Shepard, 1954). Determination of fractions based on the phi-scale (Udden-Wentworth, 1922) was also carried out. Electrical resistivity was measured using EPS-700 instrument by Vinci Technologies, using two electrode configuration in the range of 12 Hz-10 kHz. The samples were measured in their original saturated state (SW=1). Results show that the utilised techniques characterise the clay samples to a very good degree, enabling unprecedented accurate analysis of sedimentation and ground water processes.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="161f7518170dde71dbb2af31250e69b2" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":54217881,"asset_id":34318282,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/54217881/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="34318282"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="34318282"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 34318282; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=34318282]").text(description); $(".js-view-count[data-work-id=34318282]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 34318282; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='34318282']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "161f7518170dde71dbb2af31250e69b2" } } $('.js-work-strip[data-work-id=34318282]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":34318282,"title":"Development of a complex laboratory procedure for characterisation of pore structure, particle size distribution and groundwater electrical properties in sedimentary drill core samples, Lake George, NSW, Australia","translated_title":"","metadata":{"abstract":"Lake George is an intermittent lake within a closed basin 40 km north of Canberra, in New South Wales, Australia.

For classification based on grain size, we used the generally accepted nomenclature (Szakmány, 2008) and for classification based on sediment-type we used the Shepard-nomenclature (Shepard, 1954). Determination of fractions based on the phi-scale (Udden-Wentworth, 1922) was also carried out. Electrical resistivity was measured using EPS-700 instrument by Vinci Technologies, using two electrode configuration in the range of 12 Hz-10 kHz. The samples were measured in their original saturated state (SW=1). Results show that the utilised techniques characterise the clay samples to a very good degree, enabling unprecedented accurate analysis of sedimentation and ground water processes.","page_numbers":"45","publication_date":{"day":null,"month":null,"year":2017,"errors":{}},"publication_name":"HUNGEO 2017.

A multidisciplinary research project obtained a good quality 77 metres long sedimentary core from the lake bed during 2015. 17 clay samples from the core have been sent to and analysed in the GEOCHEM labs in Pécs, Hungary, during 2016. Analytical methods included He-pycnometry, physisorption, grain size analysis and electrical resistivity measurements. Plugs with different diameters (1 \" , 9 mm) were prepared with manual sampling. Fragments and plugs were dried at 80 °C in a drying oven for 12-14 days before the measurements. The geometric volume of the plugs were measured and calculated before and again after the drying process. He-pycnometry was used to measure the skeletal volume (cm 3) at 25 Celsius in both cases. Skeletal density (g/cm 3), geometric volume (cm 3), bulk density (g/cm 3) and He-porosity (%) were calculated. During physisorption, N2 (77 K) and CO2 (273 K) gas was used to obtain adsorption and desorption isotherms.

This is followed by one or more case histories, the organisational requirements of a field survey, the likely costs, and finally addresses of the main organisations providing the service.\r\n\r\nWe believe that with this volume CRCLEME is providing a service to the exploration and environmental geophysics community as well as providing a valuable aid for teaching mineral exploration students.\r\n\r\n","impression_tracking_id":null,"owner":{"id":498748,"first_name":"Eva","middle_initials":null,"last_name":"Papp","page_name":"EvaPapp","domain_name":"anu-au","created_at":"2011-06-18T15:04:45.613-07:00","display_name":"Eva Papp","url":"https://anu-au.academia.edu/EvaPapp"},"attachments":[{"id":42681225,"title":"","file_type":"jpg","scribd_thumbnail_url":"https://a.academia-assets.com/images/blank-paper.jpg","file_name":"_WRD139.jpg","download_url":"https://www.academia.edu/attachments/42681225/download_file","bulk_download_file_name":"Papp_E_ed_Geophysical_and_Remote_Sensing.jpg","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/42681225/_WRD139.jpg?1738293240=\u0026response-content-disposition=attachment%3B+filename%3DPapp_E_ed_Geophysical_and_Remote_Sensing.jpg\u0026Expires=1744157147\u0026Signature=Vhh037CCUmG3l9A1PC2U4zM-uBHISWPOQq35vqdH73f4m5ImOt3DlcSATecyIl-JONncGxweOitWCnBof~1Zpu~ILa9xxhE4zDR~seskaH08sA0UdNUlUjoMYjSnSjpXhu9ztDcfkJloYnhrv9lt77AHpGQyFV3j4gB2ZtWormePi5pRv98UxjQfLcRosQ2NBsDOIDczJvHerDo8~72omsVElSefBJTdj9pl1LdP7oUiwXa8IzQLaqRxbGplVLrHs2gSQskCimCinK0hvQ6XHwLwEjv-GX-WFTQk83h~TbjUW9gdCTDCdy9P9wcr5QVeGbIZOLBqGzm15KLMtedS5A__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"},{"id":42681226,"title":"","file_type":"jpg","scribd_thumbnail_url":"https://a.academia-assets.com/images/blank-paper.jpg","file_name":"image001.jpg","download_url":"https://www.academia.edu/attachments/42681226/download_file","bulk_download_file_name":"Papp_E_ed_Geophysical_and_Remote_Sensing.jpg","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/42681226/image001.jpg?1738293240=\u0026response-content-disposition=attachment%3B+filename%3DPapp_E_ed_Geophysical_and_Remote_Sensing.jpg\u0026Expires=1744157147\u0026Signature=dKMLu9LLhNRvU3KHIN-LL7h~z8pe3dPW2W-V35hB9H5Q6XI6pP0ebQvfqx85B~hJZkohNtLdbNYSRvp33QN-no9a4~rObdOJkUwhObnFBtC~ejluPOPsKjp7-XD74RMEbYZL4QWk2Zor5JNGZJ0JvGgqSjISXJbhpvKVrYl5WBdm0-i2lv9IyVVhpKf~TsYQQ9vfyBzwofdKHzM2txsMUSDwTchZUOxqaqva~hvsSJWNW3MkkBGzWez7fGxXQRCEZOxMmzuGGjuHg71m922BzLZixLQjnrDmJk-3lBESCymIwcHpstO8CxhgddSSuFm5Kn8TQPCIbiqvWGORB3JY8A__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[],"urls":[{"id":301465,"url":"http://crcleme.org.au/Pubs/OPEN%20FILE%20REPORTS/OFR%20144/OFR144.html"}]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") if (false) { Aedu.setUpFigureCarousel('profile-work-1765305-figures'); } }); </script> </div><div class="profile--tab_content_container js-tab-pane tab-pane" data-section-id="177223" id="papers"><div class="js-work-strip profile--work_container" data-work-id="101297078"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/101297078/High_resolution_seismic_imagery_of_palaeochannels_near_West_Wyalong_New_South_Wales"><img alt="Research paper thumbnail of High-resolution seismic imagery of palaeochannels near West Wyalong, New South Wales" class="work-thumbnail" src="https://attachments.academia-assets.com/101877573/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/101297078/High_resolution_seismic_imagery_of_palaeochannels_near_West_Wyalong_New_South_Wales">High-resolution seismic imagery of palaeochannels near West Wyalong, New South Wales</a></div><div class="wp-workCard_item"><span>Exploration Geophysics</span><span>, 2000</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Two high-resolution 2-D seismic surveys were carried out over palaeochannels near West Wyalong, N...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">Two high-resolution 2-D seismic surveys were carried out over palaeochannels near West Wyalong, NSW using an IVITM mini-vibrator.

This artwork depicts the vision of Canberra, the then future National Capital, on the shores of Lake George as an Australian Venice, with elaborate architecture, lush vegetation, sail boats and picturesque jetties, boat sheds and promenades. The artist, Charles Coulter, was an architect commissioned by the Lake George Capital Site League, a lobby group for the future National Capital to be built around Lake George, to design a parliament building and city centre around the lake. The painting was published in Melbourne in the Proceedings of the Congress of Engineers, Architects, Surveyors, and Others Interested in the Building of the Federal Capital of Australia in 1901, seven years before the location of the National Capital was decided [Barrow 2012: 60).

On the contrary, Lake George remained\na generally untouched, intermittent natural lake, mysterious and distant \nfor most Canberrans.\nThis paper summarises and contrasts the story of Lake George and\nLake Burley Griffin, underlining how landscape influenced colonial\nand modern history.","impression_tracking_id":null,"owner":{"id":498748,"first_name":"Eva","middle_initials":null,"last_name":"Papp","page_name":"EvaPapp","domain_name":"anu-au","created_at":"2011-06-18T15:04:45.613-07:00","display_name":"Eva Papp","url":"https://anu-au.academia.edu/EvaPapp"},"attachments":[{"id":58354295,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/58354295/thumbnails/1.jpg","file_name":"TOPIARIUS7_7_Papp-2.pdf","download_url":"https://www.academia.edu/attachments/58354295/download_file","bulk_download_file_name":"From_mysterious_Lake_George_to_classy_La.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/58354295/TOPIARIUS7_7_Papp-2-libre.pdf?1549581094=\u0026response-content-disposition=attachment%3B+filename%3DFrom_mysterious_Lake_George_to_classy_La.pdf\u0026Expires=1744157147\u0026Signature=FjWm3Rv0D6Pq~QQsoPwPJSoMzv8sTmAlN0j7wi2SuSKyZtoy0curTqrt5tFPcj1-N0co8Oa1RRUsF2CfggBlLt5fZQwQmkq6BZOgUmy6ARKhCqonurByqpoY7uLJospBbyfsvaEDdkv4bnq3E2ANlMZB0-2ZqbHZ2g-maXKwX9IfMTwEmYb5c-tpRLF3NDMnF2P3iliotG8iaTU62M9g~RDmb~DqRmhQlwPvTVJo7v5IrnXt8JUjgvDwVPnFBXhwkrUTk0NbM6LyXl~990gWqn7shSv8gipEGKDsKk33kLCAnJFMHQJ~uzFBBkZrI4AtqRRwB9Mmk3BqTOQgLM9j~w__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"},{"id":58354296,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/58354296/thumbnails/1.jpg","file_name":"TOPIARIUS7_7_Papp-2.pdf","download_url":"https://www.academia.edu/attachments/58354296/download_file","bulk_download_file_name":"From_mysterious_Lake_George_to_classy_La.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/58354296/TOPIARIUS7_7_Papp-2-libre.pdf?1549581137=\u0026response-content-disposition=attachment%3B+filename%3DFrom_mysterious_Lake_George_to_classy_La.pdf\u0026Expires=1744157147\u0026Signature=ARAcVxuh6IYNuiVbAfuJDedQW~LkaachCJQLrtWuwSVIrQSOHPkOa~msOW3D7Xx4Dc5Se48WoJ~KoAb2hGk-ttzlENsG2KZfVpniV9ggh~vwKhQEdHfgx8xSuAZxt7jht9cGjk07JmMIHe5etVdr7q-JrkAU5gMjItZ~ODzTVI6dzXEF-O3Xva4KeSivRqush~~RqDxyl7LZeDgJxsf-hRUfIS19Dtc9X8bjU57stEDbKomNiwQiyC3DwN62bFlU1z1IXx0OHwcfj8r0rUc8CmRICav0NjKYwMUgFkLXeY3Uofrjzh4KyjnOQRrHyWQYOhiEtfWUKRUruKM80ubBRg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":1512,"name":"Climate Change","url":"https://www.academia.edu/Documents/in/Climate_Change"},{"id":22831,"name":"Landscape","url":"https://www.academia.edu/Documents/in/Landscape"},{"id":26376,"name":"Sedimentary Basins","url":"https://www.academia.edu/Documents/in/Sedimentary_Basins"},{"id":199677,"name":"Canberra","url":"https://www.academia.edu/Documents/in/Canberra"},{"id":2478475,"name":"Lake George NSW","url":"https://www.academia.edu/Documents/in/Lake_George_NSW"},{"id":2554321,"name":"Weereewa NSW","url":"https://www.academia.edu/Documents/in/Weereewa_NSW"},{"id":3129686,"name":"Australian Capital Territory","url":"https://www.academia.edu/Documents/in/Australian_Capital_Territory"}],"urls":[{"id":8694023,"url":"http://www.topiarius.ur.edu.pl/wp-content/uploads/TOPIARIUS7_7_Papp-2.pdf"}]}, dispatcherData: dispatcherData });

There are multiple aquifers in the catchment, making it difficult to understand the impacts of groundwater extraction and irrigation. Known groundwater mounding from irrigation and decreasing hydraulic heads from groundwater extraction, combined with groundwater salinity represent a significant threat to the future of extraction and irrigation in the CIA. In this study we discovered a previously unmapped branch of a known palaeochannel system within the heavily irrigated CIA, based on radiometrics images.

Four resistivity surveys totalling 2.8 km length and 60 m depth were conducted over the paleochannel, with survey lines run parallel to irrigation channels. The results revealed a broad sandy paleochannel partially filled with clay sediments. The clay-rich regions can act as aquitards that impede downward groundwater flow and contribute to rising water tables and elevated levels of shallow groundwater salinity. The sand-rich parts of the channel can provide pathways for saline water from the shallow aquifers to leak into deeper aquifers. We also found evidence of leakage from bores and irrigation channels. Bore hydrographs show that the aquifers are well connected at depths greater than approximately 50 m, where groundwater is extracted for irrigation, but less well connected at shallower depths, reflecting the sand-rich and clay-rich parts of the channel. The shallow groundwater is saline and becomes fresher with increasing depth. Combined with strong downwards hydraulic gradients, this results in a risk to the water quality in the deeper aquifers, if the saline groundwater is transported into the freshwater aquifers at depth.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="87c09f396e17b01ab060177ba158e3e0" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":35150966,"asset_id":8803757,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/35150966/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="8803757"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="8803757"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 8803757; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=8803757]").text(description); $(".js-view-count[data-work-id=8803757]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 8803757; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='8803757']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "87c09f396e17b01ab060177ba158e3e0" } } $('.js-work-strip[data-work-id=8803757]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":8803757,"title":"Papp, É., Burraston, L. and McPhail, D.C.: Identifying palaeochannels and their influence on groundwater systems in the Lower Murrumbidgee catchment, NSW.","translated_title":"","metadata":{"abstract":"Alluvial plains are often host to major agricultural irrigation areas, such as the Coleambally Irrigation Area (CIA) in the Lower Murrumbidgee Catchment, New South Wales, Australia.

There are multiple aquifers in the catchment, making it difficult to understand the impacts of groundwater extraction and irrigation. Known groundwater mounding from irrigation and decreasing hydraulic heads from groundwater extraction, combined with groundwater salinity represent a significant threat to the future of extraction and irrigation in the CIA. In this study we discovered a previously unmapped branch of a known palaeochannel system within the heavily irrigated CIA, based on radiometrics images. We then used a combination of resistivity geophysics, geological logs, hydrogeology and hydrogeochemistry to understand the subsurface geometry of the palaeochannel and the impacts on groundwater. Four resistivity surveys totalling 2.8 km length and 60 m depth were conducted over the paleochannel, with survey lines run parallel to irrigation channels. The results revealed a broad sandy paleochannel partially filled with clay sediments. The clay-rich regions can act as aquitards that impede downward groundwater flow and contribute to rising water tables and elevated levels of shallow groundwater salinity. The sand-rich parts of the channel can provide pathways for saline water from the shallow aquifers to leak into deeper aquifers. We also found evidence of leakage from bores and irrigation channels. Bore hydrographs show that the aquifers are well connected at depths greater than approximately 50 m, where groundwater is extracted for irrigation, but less well connected at shallower depths, reflecting the sand-rich and clay-rich parts of the channel. The shallow groundwater is saline and becomes fresher with increasing depth. Combined with strong downwards hydraulic gradients, this results in a risk to the water quality in the deeper aquifers, if the saline groundwater is transported into the freshwater aquifers at depth.","impression_tracking_id":null,"owner":{"id":498748,"first_name":"Eva","middle_initials":null,"last_name":"Papp","page_name":"EvaPapp","domain_name":"anu-au","created_at":"2011-06-18T15:04:45.613-07:00","display_name":"Eva Papp","url":"https://anu-au.academia.edu/EvaPapp"},"attachments":[{"id":35150966,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/35150966/thumbnails/1.jpg","file_name":"Papp_et_al_2014.pdf","download_url":"https://www.academia.edu/attachments/35150966/download_file","bulk_download_file_name":"Papp_E_Burraston_L_and_McPhail_D_C_Ident.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/35150966/Papp_et_al_2014-libre.pdf?1413425871=\u0026response-content-disposition=attachment%3B+filename%3DPapp_E_Burraston_L_and_McPhail_D_C_Ident.pdf\u0026Expires=1744157148\u0026Signature=RGmhYW8fdqbKioMUSWiKxyzIWft5rTGJbztogD6WaZ5NFWabLyEzjkQivWmjctcNataEgbMZ1~2gif~epK16XUcFaoMIk1korCkn6q-gpM32LpR~JJ4a91yOLYhREYWeZ4GvquiR9VrBNIuPqcPIRR2~tijDNMpj4~OHcDheVTUA2YZydPFIOmEnTm26YYr9tN0nGAq4N93BV6H9lut6iL5EvFmGV~MUqQdHP1vOFvG~owgqbnjOa5kLKPfSiiDbspRaCTnUHrpZcgPSqyt1wrPXm9SCfVtFx48YGHG0OkhhZNFyV6WAlNeLNZ~px4FLWaGfZ~HT5xch8g1hjj0D7g__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":409,"name":"Geophysics","url":"https://www.academia.edu/Documents/in/Geophysics"},{"id":213575,"name":"Resistivity Imaging","url":"https://www.academia.edu/Documents/in/Resistivity_Imaging"},{"id":351709,"name":"2D and 3D geoelectrical resistivity imaging: Theory and field design","url":"https://www.academia.edu/Documents/in/2D_and_3D_geoelectrical_resistivity_imaging_Theory_and_field_design"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") if (false) { Aedu.setUpFigureCarousel('profile-work-8803757-figures'); } }); </script> <div class="js-work-strip profile--work_container" data-work-id="6227194"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/6227194/Tara_J_Deen_Karsten_Gohl_Christopher_Leslie_%C3%89va_Papp_and_Kevin_Wake_Dyster_Seismic_refraction_inversion_of_a_palaeochannel_system_in_the_Lachlan_Fold_Belt_Central_New_South_Wales"><img alt="Research paper thumbnail of Tara J.

The first aim of these seismic surveys was to map in <br />detail the profile of the palaeochannels. The second aim was to <br />establish the regolith stratigraphy within the channels and evaluate the techniques used for acquiring and processing such data. Short receiver spacings, down to one metre, were used in order to achieve satisfactory resolution of the anticipated shallow targets. The short length of the split spread meant that extra effort was required to eliminate noise close to the source. Paradigm Inc. DISCOTM/Focus software allowed interactive tests of processing parameters. A combination of bandpass filtering, spectral equalisation, mutes, and f-k filtering proved effective in suppressing noise and enhancing reflections on the shot records. Refraction statics have been calculated from the first arrivals for all the shots for both lines to reveal the shape of the uppermost layers. Examples of processing tests, as well as the interpreted seismic sections, are presented to demonstrate the effectiveness of high-resolution seismic techniques in imaging regolith stratigraphy and buried palaeochannels. <br />Preliminary results, when tied to borehole data, indicate possible <br />palaeo-erosion surfaces and maghemite gravel-filled <br />palaeochannels to 10 m depth. Saprolite and bedrock interfaces are apparent, indicating palaeotopography with relief exceeding <br />100 m.</span></div><div class="wp-workCard_item"><div class="carousel-container carousel-container--sm" id="profile-work-6193577-figures"><div class="prev-slide-container js-prev-button-container"><button aria-label="Previous" class="carousel-navigation-button js-profile-work-6193577-figures-prev"><span class="material-symbols-outlined" style="font-size: 24px" translate="no">arrow_back_ios</span></button></div><div class="slides-container js-slides-container"><figure class="figure-slide-container"><a href="https://www.academia.edu/figures/21254308/figure-1-location-map-for-west-wyalong-and-yiddah-including"><img alt="Fig. 1.

The simple examples\r\ndescribed in this paper provide insight into the developed\r\nmethodology.","impression_tracking_id":null,"owner":{"id":498748,"first_name":"Eva","middle_initials":null,"last_name":"Papp","page_name":"EvaPapp","domain_name":"anu-au","created_at":"2011-06-18T15:04:45.613-07:00","display_name":"Eva Papp","url":"https://anu-au.academia.edu/EvaPapp"},"attachments":[{"id":22549972,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/22549972/thumbnails/1.jpg","file_name":"Papp_Baxter_2002.pdf","download_url":"https://www.academia.edu/attachments/22549972/download_file","bulk_download_file_name":"Papp_E_and_Baxter_R_Factor_analysis_and.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/22549972/Papp_Baxter_2002-libre.pdf?1390867302=\u0026response-content-disposition=attachment%3B+filename%3DPapp_E_and_Baxter_R_Factor_analysis_and.pdf\u0026Expires=1744157148\u0026Signature=CbK-TnA5mijTLLUwPS-ZX5ibuUEFqWhY7WUb8qiWUxcymrpURy7YvZOzSGhBGPceZ4HxmIIVZLHT852UtNRoAiUSIF6CqS7W0OUZSMJCONdDfyHD~bsFhrScpTHn1F7oHTjEPy5v2U9VRyFkQQQaQlB-ktioOtmrWIzoNJq4CVe~JYB9H9jCYRsOk-~yXeTvL~QeIiIGUYJNltkBhhyRmFPZrvgwmluUkHGo7H2qpN1Tj78qIOaU7LLfvz7shEcvFq0P-z~PTUEspGCC4U~9CuNSOmAqL9BqNQ1RPWNCSVnTC4DKCWnyHwJhIMu~xErJg8PLp7UHwaw8KFrps1E0yA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") if (false) { Aedu.setUpFigureCarousel('profile-work-1765277-figures'); } }); </script> <div class="js-work-strip profile--work_container" data-work-id="1765605"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" rel="nofollow" href="https://www.academia.edu/1765605/%C3%89va_Papp_Ground_Penetrating_Radar_survey_of_the_Casey_road"><img alt="Research paper thumbnail of Éva Papp: Ground Penetrating Radar survey of the Casey road.

Compositional data suggest that the iron loss starts at petrologic class 6; at classes 6 and 7 of any chondrite type metallic iron (and maybe FeS) is less than for 1-5.","impression_tracking_id":null,"owner":{"id":498748,"first_name":"Eva","middle_initials":null,"last_name":"Papp","page_name":"EvaPapp","domain_name":"anu-au","created_at":"2011-06-18T15:04:45.613-07:00","display_name":"Eva Papp","url":"https://anu-au.academia.edu/EvaPapp"},"attachments":[{"id":53739900,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/53739900/thumbnails/1.jpg","file_name":"mineralogica_039_087-105.pdf","download_url":"https://www.academia.edu/attachments/53739900/download_file","bulk_download_file_name":"Sz_Berczi_B_Lukacs_A_Holba_A_Kiss_and_E.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/53739900/mineralogica_039_087-105-libre.pdf?1499073204=\u0026response-content-disposition=attachment%3B+filename%3DSz_Berczi_B_Lukacs_A_Holba_A_Kiss_and_E.pdf\u0026Expires=1744157148\u0026Signature=FTlPcd4L2hKbnvbSd9Zn3BGhDY~5PYelrFj0uWEtqd32UzyUh1RSz48utD~jhxVveVGWeO5zy3KzLXBpo5n4qt215dWZsAvcESnu3yzF6FVIL-zLaW-FdwldWqSi7wiuu7nH~AAcABAxHKRbloGM~XkVF~0fsbUemE9s-23ZdlCGc75NYgPrkmL6IzYohNVZwSuT2pFPh90RTy0Sf4BVo7qWBtUG0v-51byQ4wZ71JLuatW00nP09Bl7saPQOkje2xy7khZtsbI0n9O7p153Yl7fWj9uRjiLD-ltECwLPP~ZAXMiYLXmxyMxHlGBkeLeDVFXrFrXN8KuPEi1NemDPg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") if (true) { Aedu.setUpFigureCarousel('profile-work-1767076-figures'); } }); </script> <div class="js-work-strip profile--work_container" data-work-id="1767083"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" rel="nofollow" href="https://www.academia.edu/1767083/B_Luk%C3%A1cs_Sz_B%C3%A9rczi_S_J%C3%B3zsa_Gy_Szakm%C3%A1ny_and_%C3%89_Papp_Thermal_transformations_in_the_meteorite_parent_bodies_II"><img alt="Research paper thumbnail of B.

Regolith logging with a small, easy-to-use geophysical logging system, mounted in a 4WD vehicle. Geophysical well logging offers the opportunity of determining the composition, variability and physical properties of the rocks around the borehole. The actual volume of material sampled in this way varies from technique to technique and with the geological conditions, but it is invariably much larger than is represented by just the borehole. Moreover, depth control with a modern geophysical logging system is often better than a few millimetres. This means that the depth resolution of borehole data, representing the subsurface structure, is generally better than can be obtained even with diamond coring, where core breakage and core loss can be a serious problem, especially in regolith. Modern geophysical logging systems can be easily deployed from 4WD vehicles, using digital, computerised. small svstems. such as the one shown jn Ficure 3.

Note that resistivity logs only work if the downhole probe is below the water table. This can be a limitation for some shallow regolith studies unless water can be added to the borehole to artificially raise the level to the area of interest. Single-point resistivity logging measures the resistivity between a single moving electrode downhole and an earth connection at the surface. Theoretical analysis and practical observation shows however that the bulk of the signal is in fact generated within a small volume surrounding the downhole electrode. Thus for a 5 cm diameter spherical electrode, 90% of the signal is generated within 50 cm of the electrode.

Saline groundwater which is in contact with clay-rich materials often develop charge imbalances (ie. potentials) as a result of fluid flow.

A multidisciplinary research project obtained a good quality 77 metres long sedimentary core from the lake bed during 2015. 17 clay samples from the core have been sent to and analysed in the GEOCHEM labs in Pécs, Hungary, during 2016. Analytical methods included He-pycnometry, physisorption, grain size analysis and electrical resistivity measurements. Plugs with different diameters (1 " , 9 mm) were prepared with manual sampling. Fragments and plugs were dried at 80 °C in a drying oven for 12-14 days before the measurements. The geometric volume of the plugs were measured and calculated before and again after the drying process. He-pycnometry was used to measure the skeletal volume (cm 3) at 25 Celsius in both cases. Skeletal density (g/cm 3), geometric volume (cm 3), bulk density (g/cm 3) and He-porosity (%) were calculated. During physisorption, N2 (77 K) and CO2 (273 K) gas was used to obtain adsorption and desorption isotherms. Nitrogen was used to measure BET surface (m 2 /g), pore size distribution (Barrett-Joyner-Halenda method), fractal dimension (Frenkel-Halsey-Hill method), and pore volume (cm 3 /g). CO2 gas is very suitable for examination of micro-pores (d < 2 nm) (Condon, 2006). In this study we calculated micro-pore volume and surface area using the Dubinin-Radushkevich method. During particle size analysis, we determined average grain size and grain size distribution, using CILAS 1180 LD type laser granulometer. For classification based on grain size, we used the generally accepted nomenclature (Szakmány, 2008) and for classification based on sediment-type we used the Shepard-nomenclature (Shepard, 1954). Determination of fractions based on the phi-scale (Udden-Wentworth, 1922) was also carried out. Electrical resistivity was measured using EPS-700 instrument by Vinci Technologies, using two electrode configuration in the range of 12 Hz-10 kHz. The samples were measured in their original saturated state (SW=1). Results show that the utilised techniques characterise the clay samples to a very good degree, enabling unprecedented accurate analysis of sedimentation and ground water processes.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="161f7518170dde71dbb2af31250e69b2" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":54217881,"asset_id":34318282,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/54217881/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="34318282"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="34318282"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 34318282; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=34318282]").text(description); $(".js-view-count[data-work-id=34318282]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 34318282; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='34318282']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "161f7518170dde71dbb2af31250e69b2" } } $('.js-work-strip[data-work-id=34318282]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":34318282,"title":"Development of a complex laboratory procedure for characterisation of pore structure, particle size distribution and groundwater electrical properties in sedimentary drill core samples, Lake George, NSW, Australia","translated_title":"","metadata":{"abstract":"Lake George is an intermittent lake within a closed basin 40 km north of Canberra, in New South Wales, Australia.

For classification based on grain size, we used the generally accepted nomenclature (Szakmány, 2008) and for classification based on sediment-type we used the Shepard-nomenclature (Shepard, 1954). Determination of fractions based on the phi-scale (Udden-Wentworth, 1922) was also carried out. Electrical resistivity was measured using EPS-700 instrument by Vinci Technologies, using two electrode configuration in the range of 12 Hz-10 kHz. The samples were measured in their original saturated state (SW=1). Results show that the utilised techniques characterise the clay samples to a very good degree, enabling unprecedented accurate analysis of sedimentation and ground water processes.","page_numbers":"45","publication_date":{"day":null,"month":null,"year":2017,"errors":{}},"publication_name":"HUNGEO 2017.

A multidisciplinary research project obtained a good quality 77 metres long sedimentary core from the lake bed during 2015. 17 clay samples from the core have been sent to and analysed in the GEOCHEM labs in Pécs, Hungary, during 2016. Analytical methods included He-pycnometry, physisorption, grain size analysis and electrical resistivity measurements. Plugs with different diameters (1 \" , 9 mm) were prepared with manual sampling. Fragments and plugs were dried at 80 °C in a drying oven for 12-14 days before the measurements. The geometric volume of the plugs were measured and calculated before and again after the drying process. He-pycnometry was used to measure the skeletal volume (cm 3) at 25 Celsius in both cases. Skeletal density (g/cm 3), geometric volume (cm 3), bulk density (g/cm 3) and He-porosity (%) were calculated. During physisorption, N2 (77 K) and CO2 (273 K) gas was used to obtain adsorption and desorption isotherms.

Manual auger samples, collected up to 250cm depth, were analysed using X-Ray powder diffractometry, to characterise the resistivity anomalies. Particular attention was paid to the geophysical inversion method and to the identification and quantification of minerals in auger samples. The smoothness-constrained least-squares optimisation method produced a modelled resistivity bounded between 20 and 600 Ωm, with a vertical discontinuity at depth (~15m and downwards) near the middle of the pseudosection, and a clear delimitation of groundwater in the first 15m below the surface.

The nature of the deep resistive discontinuity could be the result of a conductive/resistive dyke or a local fault, interpretations that are supported by previously published geological map and aeromagnetic data, but for which the auger samples are of little use.","impression_tracking_id":null,"owner":{"id":498748,"first_name":"Eva","middle_initials":null,"last_name":"Papp","page_name":"EvaPapp","domain_name":"anu-au","created_at":"2011-06-18T15:04:45.613-07:00","display_name":"Eva Papp","url":"https://anu-au.academia.edu/EvaPapp"},"attachments":[{"id":46395821,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/46395821/thumbnails/1.jpg","file_name":"Preview_2015n179p25.pdf","download_url":"https://www.academia.edu/attachments/46395821/download_file","bulk_download_file_name":"Manon_Dalaison_Investigation_of_the_natu.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/46395821/Preview_2015n179p25-libre.pdf?1465644511=\u0026response-content-disposition=attachment%3B+filename%3DManon_Dalaison_Investigation_of_the_natu.pdf\u0026Expires=1744157149\u0026Signature=VS7GxIPfeiCAfVSMi1cQeJXCcNOQzrgv9fBxDrDwtWuo-qTCHTIr6yYhVqOYn5LdRZhpprDpV~v65WXvxkSPtretSKzu3KrBZ2Sz2Fr6ba2rVoz2LfiJXpQ4IM6X7yWib-TIApyAy5yq5CvVqqIvMv23X5KGJfLNsisIlTYx6g89KezDGBFbd9rdKEa4WkXUhQ-u0mGr47aKLaAIuFVtsk0mhkc1cCjmwxeuDzFby084AU5pUd92fz1oLKLbDQAXHjdHYXid3shEi-TFohXfKXEBl1KfRnbnqr4C3SH8AY2RkSUAkm758BN34Xx8QpRpVsgsp3iOc4xB804VcckA3w__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"},{"id":46264932,"title":"","file_type":"docx","scribd_thumbnail_url":"https://attachments.academia-assets.com/46264932/thumbnails/1.jpg","file_name":"Abstract_for_Preview.docx","download_url":"https://www.academia.edu/attachments/46264932/download_file","bulk_download_file_name":"Manon_Dalaison_Investigation_of_the_natu.docx","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/46264932/Abstract_for_Preview.docx?1738322217=\u0026response-content-disposition=attachment%3B+filename%3DManon_Dalaison_Investigation_of_the_natu.docx\u0026Expires=1744157149\u0026Signature=WBJ84sYaQ9oVX~5KZGQKpssM704i4bUcb~2TvJdeXlTAea6q62-z8SzNhB8O7L0GyywFm6r9afzCUFHSi68z-qiQ2xOrPAgkAkDlne-b4OgrNAAxJxmuVy9ZZ49nhMzZVPdDQ4VQdiWsiakmocRMOY~Vp1otJMHyMlaZminEEn9rTHOG8yJDNNwxV5kBYLY2RTdLRSYpQVWvYDcxFy1ewJO5Cqq5RAYtmgrh~z2x95d-RurpJ7GlW3DZuWF9kpjcpuHv~yxpnFveeurr5cbRCdzu7Vmb74Qh6MW-fxAPTh5Mp7xlwRr6YJYTLHCZbv3UR6CQVinsmMVnyu~c-NiJeQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":16493,"name":"Rock weathering","url":"https://www.academia.edu/Documents/in/Rock_weathering"},{"id":61623,"name":"Applied Geophysics","url":"https://www.academia.edu/Documents/in/Applied_Geophysics"},{"id":191577,"name":"Resistivity","url":"https://www.academia.edu/Documents/in/Resistivity"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") if (false) { Aedu.setUpFigureCarousel('profile-work-25900724-figures'); } }); </script> <div class="js-work-strip profile--work_container" data-work-id="11287700"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/11287700/Sanjay_Govindan_The_relationship_between_pore_space_and_the_electrical_resistivity_signature_of_in_situ_regolith_at_Major_s_Creek_NSW_Special_Topic_3050_Semester_2_2014_"><img alt="Research paper thumbnail of Sanjay Govindan: The relationship between pore space and the electrical resistivity signature of in-situ regolith at Major’s Creek, NSW.

Unexpected trends between pore space and the electrical resistivity signature of the 5 samples provide an interesting incite to delineate in-situ regolith from fresh bed rock in a porphyry environment. The deeper samples (3, 4 and 5) seem to follow an exponential trend; increase in resistivity and depth with a decrease in pore space, a trend that mirrors Archie’s law (1942). The shallower samples (1 and 2) follow the opposite trend, an increase in pore space with a decrease in resistivity. The disparity between shallow (samples 1 and 2) and deeper (Samples 3, 4, and 5) trend might be consistent with the enrichment of Fe-Oxide (Fe-Ox) at the depth of sample 2 (17.5m). Consequently, electrical resistivity signature induced from the Fe-Ox enrichment and limited pore space of sample 2 might be the signpost for delineating fresh rock from in-situ regolith. The presence of Fe-Ox enrichment and limited pore space (0.14%) could act as a conductive aquitard to meteroric waters above, providing a boundary between the interface of highly weathered and fresh granitic rock. Despite some promise in the trends made apparent in this paper, a greater range of area, deeper core samples and more accurate sampling techniques are required to establish any further trends or theories.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="8d3a1b57b8d2fc5926c9af86a146890a" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":36866858,"asset_id":11287700,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/36866858/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="11287700"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="11287700"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 11287700; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=11287700]").text(description); $(".js-view-count[data-work-id=11287700]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 11287700; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='11287700']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "8d3a1b57b8d2fc5926c9af86a146890a" } } $('.js-work-strip[data-work-id=11287700]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":11287700,"title":"Sanjay Govindan: The relationship between pore space and the electrical resistivity signature of in-situ regolith at Major’s Creek, NSW.

Groundwater mounding and associated shallow groundwater salinity represents a significant threat to the future of irrigation in the CIA. Many groundwater studies are focussed on interactions between groundwater and natural surface water features such as rivers and lakes. This study seeks to develop an improved understanding of the specific impact of irrigation on surface water and groundwater interactions.<br />Four resistivity surveys totalling 2.8 km in length and with a depth penetration of 60 m were carried out parallel to irrigation channels at a site within the heavily irrigated CIA. Geophysical inversion was carried out, and subsequent geological interpretation was achieved with the use of multiple ancillary data types including airborne radiometrics, Landsat imagery, hydrogeochemical and hydrogeological data, as well as information from geological logs.<br />A previously unmapped branch of a known palaeochannel system was discovered from radiometrics images. Detailed subsurface geometry of this palaeochannel from resistivity imaging combined with information from geological logs revealed a broad sandy feature partially filled with clay sediments.

This study investigates how the geophysical technique of resistivity imaging can be combined with more established techniques of hydrogeology and hydrogeochemistry to improve understanding of surface water – groundwater interactions, focusing on the Narrandera area of the Lower Murrumbidgee Catchment.<br />Four resistivity surveys totalling 3.3 km were conducted in three locations: along the line of an existing hydrogeology cross-section; within a meander of the Murrumbidgee River; and at a site of ongoing groundwater monitoring, 15 km south of the river. The resulting resistivity sections were interpreted with the assistance of drillers’ logs, water chemistry data, hydraulic head measurements, Landsat imagery and radiometrics data.<br />Both the resistivity imaging and Landsat imagery provides evidence that there is a paleochannel that acts as a high hydraulic conductivity conduit, parallel to the current Murrumbidgee River. Evidence of groundwater flow following the river meander is seen in two resistivity sections. There is evidence of water flowing along surface features and entering the groundwater system near the river. This, combined with hydraulic gradients away from the river downstream of Narrandera, provides strong evidence for recharge coming from the river. The groundwater composition is progressively less river-like further from the river suggesting mixing of river water and existing groundwater.<br />Two possible mechanisms for vertical flow between aquifers have been identified. The first is leakage associated with bores. Significant leakage through a monitoring bore (GW025395) has been identified by its strong resistivity signature. Given the large number of bores in the catchment, leakage may substantially influence the region’s hydrodynamics. The second mechanism is a density driven flow due to highly saline shallow groundwater sinking.<br />This study demonstrates the power of resistivity imaging in studying groundwater particularly when combined with other methods. Resistivity imaging has been most useful for detailed mapping of features associated with paleochannels.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="11286844"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="11286844"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 11286844; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=11286844]").text(description); $(".js-view-count[data-work-id=11286844]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 11286844; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='11286844']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=11286844]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":11286844,"title":"Rebecca Garner: Resistivity imaging and surface water – groundwater interactions in the Lower Murrumbidgee Catchment.

Ongoing use of groundwater resources for irrigation is problematical because of the complexity of multiple aquifer systems there, a result of past changes in fluvial environments. Groundwater extraction from deep aquifers, plus groundwater mounding and associated shallow salinity, represent a significant threat to the future of irrigation in the CIA. In this study, we combined several methods to characterise the complex alluvial environment at a site in the CIA and understand the potential impacts of extraction and irrigation on water resources. From radiometrics images, we discovered a previously unmapped branch of a known palaeochannel system. Detailed subsurface geometry of this palaeochannel from resistivity imaging, combined with information from geological logs, revealed a broad sandy feature partially filled with clay sediments. There is also evidence of leakage from nearby irrigation channels into the groundwater system. Hydrogeological and hydrogeochemical data help understand how the partially clay-filled palaeochannel can act as an aquitard to groundwater flow, contributing to rising water tables and elevated levels of shallow groundwater salinity.

This study highlights the need to identify major geomorphological features and how they can influence the use of groundwater resources, especially in irrigated areas, and shows the effectiveness of using multiple geophysical techniques, in combination with other methods, to characterise complex alluvial paleoenvironments.","impression_tracking_id":null,"owner":{"id":498748,"first_name":"Eva","middle_initials":null,"last_name":"Papp","page_name":"EvaPapp","domain_name":"anu-au","created_at":"2011-06-18T15:04:45.613-07:00","display_name":"Eva Papp","url":"https://anu-au.academia.edu/EvaPapp"},"attachments":[{"id":116290288,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/116290288/thumbnails/1.jpg","file_name":"Full_program_and_abstracts_AQUA_2014.pdf","download_url":"https://www.academia.edu/attachments/116290288/download_file","bulk_download_file_name":"Geophysics_palaeochannels_and_groundwate.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/116290288/Full_program_and_abstracts_AQUA_2014-libre.pdf?1719145586=\u0026response-content-disposition=attachment%3B+filename%3DGeophysics_palaeochannels_and_groundwate.pdf\u0026Expires=1744157149\u0026Signature=dqEAIhxXeki0WYtJJqJG~5dd8Zr~Wbx3nBzwEDWxuSkrB3hWqY2qtXIS8ExThmqGEBkOPhbgSH4UJaozyGZfLJ2UDGGzKmrfpqJHEqcrhZ-aRRiO8wLdULMNGDg1BMN6N74bDSC-eMQBv~J9PLb6A3Xc-zQl1KD6LggTQgfj7~DW2ToCSUZuqJF~nDn676ZwUwaFv7zqT2eOtXWJZBGUKunSBC5zR6Lfugq5faaO0vjYQik4s7oP9M2DRACA7mvpKoXMLx5E7NBWFJKPsGe25HQFXRzVcMDVETA4xEZ9zR7OQyYMA41XKy-isDQd3QlliaKbDZnAiaeF0iGG0KznnQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":7075,"name":"Paleoenvironment","url":"https://www.academia.edu/Documents/in/Paleoenvironment"},{"id":34760,"name":"Irrigation water Management","url":"https://www.academia.edu/Documents/in/Irrigation_water_Management"},{"id":60446,"name":"Quaternary Sedimentology and Geomorphology","url":"https://www.academia.edu/Documents/in/Quaternary_Sedimentology_and_Geomorphology"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") if (true) { Aedu.setUpFigureCarousel('profile-work-121404736-figures'); } }); </script> <div class="js-work-strip profile--work_container" data-work-id="40373621"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/40373621/Trace_fossils_as_indicators_of_Quaternary_environmental_changes_at_Weereewa_Lake_George"><img alt="Research paper thumbnail of Trace fossils as indicators of Quaternary environmental changes at Weereewa (Lake George" class="work-thumbnail" src="https://attachments.academia-assets.com/60622145/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/40373621/Trace_fossils_as_indicators_of_Quaternary_environmental_changes_at_Weereewa_Lake_George">Trace fossils as indicators of Quaternary environmental changes at Weereewa (Lake George</a></div><div class="wp-workCard_item wp-workCard--coauthors"><span>by </span><span><a class="" data-click-track="profile-work-strip-authors" href="https://anu-au.academia.edu/EvaPapp">Eva Papp</a> and <a class="" data-click-track="profile-work-strip-authors" href="https://unideb.academia.edu/DavidArpad">David Arpad</a></span></div><div class="wp-workCard_item"><span>IAS Roma </span><span>, 2019</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Weereewa, re-named by white settlers to Lake George in 1820, is an intermittent lake 40 km northe...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">Weereewa, re-named by white settlers to Lake George in 1820, is an intermittent lake 40 km northeast of Canberra, Australia’s National Capital.

The water level in the lake bed, indicated by trace fossils, follows a similar trend to that is indicated by the high resolution sedimentary log, obtained from the same drill hole.\n","impression_tracking_id":null,"owner":{"id":498748,"first_name":"Eva","middle_initials":null,"last_name":"Papp","page_name":"EvaPapp","domain_name":"anu-au","created_at":"2011-06-18T15:04:45.613-07:00","display_name":"Eva Papp","url":"https://anu-au.academia.edu/EvaPapp"},"attachments":[{"id":60622145,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/60622145/thumbnails/1.jpg","file_name":"IASROMA_2019_Poster_final_DA_EP1020190917-114400-l467jf.pdf","download_url":"https://www.academia.edu/attachments/60622145/download_file","bulk_download_file_name":"Trace_fossils_as_indicators_of_Quaternar.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/60622145/IASROMA_2019_Poster_final_DA_EP1020190917-114400-l467jf-libre.pdf?1568720553=\u0026response-content-disposition=attachment%3B+filename%3DTrace_fossils_as_indicators_of_Quaternar.pdf\u0026Expires=1744157150\u0026Signature=WKRx8n2OvqfmXD-ReFcLhZrEFHnbWtwhxajZn0FTwFZJ3nvBaROoiCmmLZQqUNYS6ZD5o5w5J2wiMqr2JwlQDTvI11Fgc30~JBd3SvLASXvFcnQ1wLBaTKMUejyZ0GB8VCRWhEY3loOM5RVLlLLbIyDn7gkxsTRY19srS3DcpzKU6JrywY97scB1qYnTvhd4WzBuT8Y115lIYZdTjjawbcOXtOpGY38iZ6tzbcKp9xsiCli5gjpOlYIHVQWyzjVvRVKdZCHY49pqyo2pI-n20CmzzylxcXJvEeJsE69euColy16sRJ3NVgJXRzEKA7keIbWPsHDE3juShEClfQNviQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":1512,"name":"Climate Change","url":"https://www.academia.edu/Documents/in/Climate_Change"},{"id":9890,"name":"Quaternary Geology","url":"https://www.academia.edu/Documents/in/Quaternary_Geology"},{"id":23422,"name":"Paleoclimate","url":"https://www.academia.edu/Documents/in/Paleoclimate"},{"id":60446,"name":"Quaternary Sedimentology and Geomorphology","url":"https://www.academia.edu/Documents/in/Quaternary_Sedimentology_and_Geomorphology"},{"id":60487,"name":"Quaternary environments","url":"https://www.academia.edu/Documents/in/Quaternary_environments"},{"id":70233,"name":"Trace Fossils","url":"https://www.academia.edu/Documents/in/Trace_Fossils"},{"id":96118,"name":"Quaternary environmental change","url":"https://www.academia.edu/Documents/in/Quaternary_environmental_change"},{"id":199677,"name":"Canberra","url":"https://www.academia.edu/Documents/in/Canberra"},{"id":2478475,"name":"Lake George NSW","url":"https://www.academia.edu/Documents/in/Lake_George_NSW"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") if (false) { Aedu.setUpFigureCarousel('profile-work-40373621-figures'); } }); </script> <div class="js-work-strip profile--work_container" data-work-id="39934384"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/39934384/The_interaction_between_vegetation_megafauna_and_fire_regimes_at_Lake_George_southeastern_Australia"><img alt="Research paper thumbnail of The interaction between vegetation, megafauna and fire regimes at Lake George, southeastern Australia" class="work-thumbnail" src="https://attachments.academia-assets.com/60121692/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/39934384/The_interaction_between_vegetation_megafauna_and_fire_regimes_at_Lake_George_southeastern_Australia">The interaction between vegetation, megafauna and fire regimes at Lake George, southeastern Australia</a></div><div class="wp-workCard_item wp-workCard--coauthors"><span>by </span><span><a class="" data-click-track="profile-work-strip-authors" href="https://anu-au.academia.edu/EvaPapp">Eva Papp</a> and <a class="" data-click-track="profile-work-strip-authors" href="https://anu-au.academia.edu/PhillipRoberts">Phillip Roberts</a></span></div><div class="wp-workCard_item"><span>INQUA, Dublin</span><span>, 2019</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">The Lake George basin on the Southern Tablelands of New South Wales, in southeastern Australia, c...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">The Lake George basin on the Southern Tablelands of New South Wales, in southeastern Australia, contains the longest known quasi-continuous sedimentary record of any Australian lake basin.

The similar trending of Eucalytpus and at times Casuarinaceae with the microcharcoa and macrocharcoal may suggest a local to regional origin for both charcoals. The abundance of saline tolerant algal spores Zygnema, Mougeotia, Spirogyra and Botryococcus may suggest relatively shallow saline lake conditions, while the presence o Pediastrum, Tetraedron and Azolla suggests periods where more fresh water conditions and/or input is present. The significan values for Pediastrum in the middle of the record may be influential in the high fern values seen at this time which may sugges an extra-local rather than local origin. A closer look at the sedimentology and depositional environment may provide answers tc the fern origin. The presence of dung fungi, especially Sporormiella, suggests the presence of large herbivores within the Lake \. George basin 5 Chenopodiaceae (Amaranthaceae), Asteraceae, Poaceae and the sclerophylls (Casuarinaceae and Eucalyptus) are the major contributors to the dryland taxa (Figure 4). Through the barren/sparse pollen zone, Figure 2 (A and B) and Figure 4, ferns are abundant. In the latter part of the record a diverse suite of taxa are present (Figure 4) including Tasmannia, Amperea, Acaena, Coprosma, Astrotricha, Stackhousia and Gyrostemon which are not found at the top of the record. Dung fungi, Sporormiella, Podospora and Sordaria, are present at the top of the record and when dryland pollen is abundant. Algal spores from the Zygnemataceae family, Spirogryra, Mougeotia and Zygnema are found through most of the record while Tetraedron (Hydrodictyaceae) is only in the earlier part of the record.

A multidisciplinary research project obtained a good quality 77 meter-long sedimentary core from the lake bed during 2015. 17 clay samples from the core have been sent to and analyzed in the GEOCHEM laboratories to understand sedimentary pore structure and its changes. From several methods tried, He-pycnometry, physisorption and grain size analysis provided the most useful information for complex interpretation. Here the applied\nmethodology is demonstrated, on the example of three samples selected from different depth. Although all three samples have been deposited in a calm, flow-free sedimentary environment, the pore structure of each of them is different, particularly on mesopore level. These differences allow a very high-resolution study of past sedimentary\nenvironments.\n\nÖsszefoglaló\nA Lake George Ausztráliában, Canberrától 40 km-re északra, Új Dél Wales-ben található zárt vízgyűjtő medencéjű időszakos tó. 2015 során, egy multidiszciplináris kutatási projekt keretében végzett kutatófúrás 77 méter jó minőségű fúrásmagot eredményezett, melyből 17 minta került a GEOCHEM Kft. laboratóriumába részletes elemzésre. Az előzetes eredmények alapján a He-piknometria, a fiziszorpció és a szemcseméret analízis adták a komplex értelmezéshez leginkább használható információkat. Az alkalmazott módszerek bemutatása céljából három, eltérő mélységből származó minta került kiválasztásra. Az eredmények azt mutatják, hogy bár mindhárom minta nyugodtvízi, áramlásoktól mentes üledékes lerakódási környezetben képződött, alapvetően különböző pórusszerkezeti tulajdonságokkal bírnak, különösen a mezopórusok tartományában.

A tó a Kelet-Ausztráliai Tábla D-i részén egy lefolyástalan medencében helyezkedik el, melyet nyugaton a Lake George törésvonal, keleten pedig paleozoos földtani képződmények határolnak. A jelenlegi tómedence mintegy 20 km x 10 km kiterjedésű, és 680 m tengerszint feletti magasságban helyezkedik el. 2015-ben az Australian National University egy új, 77 m mélységű fúrást mélyített a tó medencéjének NY-i peremén. Ez a mag kevesebb mállott részt tartalmaz, és a pollenek is job megtartásúak benne, mint az előzőekben. A fúrás alapjának becsült kora 2,2-2,5 millió év.

The results will assist in identification, and further studies will provide more information on proprioception of this unique animal. \n","impression_tracking_id":null,"owner":{"id":498748,"first_name":"Eva","middle_initials":null,"last_name":"Papp","page_name":"EvaPapp","domain_name":"anu-au","created_at":"2011-06-18T15:04:45.613-07:00","display_name":"Eva Papp","url":"https://anu-au.academia.edu/EvaPapp"},"attachments":[{"id":54738676,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/54738676/thumbnails/1.jpg","file_name":"2017_Poster_CAVEPS.pdf","download_url":"https://www.academia.edu/attachments/54738676/download_file","bulk_download_file_name":"Reconstruction_and_anatomical_descriptio.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/54738676/2017_Poster_CAVEPS-libre.pdf?1508233284=\u0026response-content-disposition=attachment%3B+filename%3DReconstruction_and_anatomical_descriptio.pdf\u0026Expires=1744157150\u0026Signature=CkGLPtgh-x35le0Thj7qKvl7dqZFWpcfZvNU7vLVNyOWdVnMeXX30YllM~r8InvczopsM-muw7nJ0HmHx9tbE893syuyGT88D3lcg57Aipeo4s57VnU9Hn8ctcfF7450qV8dI7avXZQta3E~9Hmw7pTdkBNVztellS7ccHLFq2ZmKaky8CWeVKVSP-TFy5Y8Lztt7GHOzw3J5001VnFNSWixEUd5LoXgKu1EIEljQw7skPr1Ak-vrwo7QDu-VfDs1opIULFFTpZvJSPSSUux9nryPMt04KHgGe4WfcU8RSDlOZhccpjzOMmHEheHaD3b25i71WwGrbpuLd2JOXec~w__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":417,"name":"Paleontology","url":"https://www.academia.edu/Documents/in/Paleontology"},{"id":3031,"name":"Auditory Perception","url":"https://www.academia.edu/Documents/in/Auditory_Perception"},{"id":10574,"name":"Auditory Neuroscience","url":"https://www.academia.edu/Documents/in/Auditory_Neuroscience"},{"id":19363,"name":"Vertebrate Evolution","url":"https://www.academia.edu/Documents/in/Vertebrate_Evolution"},{"id":24375,"name":"Vertebrate Paleontology","url":"https://www.academia.edu/Documents/in/Vertebrate_Paleontology"},{"id":54214,"name":"Proprioception","url":"https://www.academia.edu/Documents/in/Proprioception"},{"id":236794,"name":"Pleistocene megafauna","url":"https://www.academia.edu/Documents/in/Pleistocene_megafauna"},{"id":435282,"name":"Diprotodontids","url":"https://www.academia.edu/Documents/in/Diprotodontids"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") if (false) { Aedu.setUpFigureCarousel('profile-work-34878976-figures'); } }); </script> <div class="js-work-strip profile--work_container" data-work-id="34878730"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/34878730/Development_of_a_complex_laboratory_procedure_for_characterisation_of_pore_structure_particle_size_distribution_and_groundwater_electrical_properties_in_sedimentary_drill_core_samples_Lake_George_NSW_Australia"><img alt="Research paper thumbnail of Development of a complex laboratory procedure for characterisation of pore structure, particle size distribution and groundwater electrical properties in sedimentary drill core samples, Lake George, NSW, Australia" class="work-thumbnail" src="https://attachments.academia-assets.com/54738410/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/34878730/Development_of_a_complex_laboratory_procedure_for_characterisation_of_pore_structure_particle_size_distribution_and_groundwater_electrical_properties_in_sedimentary_drill_core_samples_Lake_George_NSW_Australia">Development of a complex laboratory procedure for characterisation of pore structure, particle size distribution and groundwater electrical properties in sedimentary drill core samples, Lake George, NSW, Australia</a></div><div class="wp-workCard_item wp-workCard--coauthors"><span>by </span><span><a class="" data-click-track="profile-work-strip-authors" href="https://anu-au.academia.edu/EvaPapp">Eva Papp</a> and <a class="" data-click-track="profile-work-strip-authors" href="https://independent.academia.edu/FerencFedor">Ferenc Fedor</a></span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Lake George is an intermittent lake within a closed basin 40 km north of Canberra, in New South W...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">Lake George is an intermittent lake within a closed basin 40 km north of Canberra, in New South Wales, Australia. A multidisciplinary research project obtained a good quality 77 metres long sedimentary core from the lake bed during 2015. 17 clay samples from the core have been sent to and analysed in the GEOCHEM labs in Pécs, Hungary, during 2016. Analytical methods included He-pycnometry, physisorption, grain size analysis and electrical resistivity measurements. Plugs with different diameters (1 " , 9 mm) were prepared with manual sampling. Fragments and plugs were dried at 80 °C in a drying oven for 12-14 days before the measurements. The geometric volume of the plugs were measured and calculated before and again after the drying process. He-pycnometry was used to measure the skeletal volume (cm 3) at 25 Celsius in both cases. Skeletal density (g/cm 3), geometric volume (cm 3), bulk density (g/cm 3) and He-porosity (%) were calculated. During physisorption, N2 (77 K) and CO2 (273 K) gas was used to obtain adsorption and desorption isotherms. Nitrogen was used to measure BET surface (m 2 /g), pore size distribution (Barrett-Joyner-Halenda method), fractal dimension (Frenkel-Halsey-Hill method), and pore volume (cm 3 /g). CO2 gas is very suitable for examination of micro-pores (d < 2 nm) (Condon, 2006). In this study we calculated micro-pore volume and surface area using the Dubinin-Radushkevich method. During particle size analysis, we determined average grain size and grain size distribution, using CILAS 1180 LD type laser granulometer. For classification based on grain size, we used the generally accepted nomenclature (Szakmány, 2008) and for classification based on sediment-type we used the Shepard-nomenclature (Shepard, 1954). Determination of fractions based on the phi-scale (Udden-Wentworth, 1922) was also carried out. Electrical resistivity was measured using EPS-700 instrument by Vinci Technologies, using two electrode configuration in the range of 12 Hz-10 kHz. The samples were measured in their original saturated state (SW=1). Results show that the utilised techniques characterise the clay samples to a very good degree, enabling unprecedented accurate analysis of sedimentation and ground water processes.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="05e432eac12fe700517e9f55e9c639a2" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":54738410,"asset_id":34878730,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/54738410/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="34878730"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="34878730"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 34878730; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=34878730]").text(description); $(".js-view-count[data-work-id=34878730]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 34878730; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='34878730']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "05e432eac12fe700517e9f55e9c639a2" } } $('.js-work-strip[data-work-id=34878730]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":34878730,"title":"Development of a complex laboratory procedure for characterisation of pore structure, particle size distribution and groundwater electrical properties in sedimentary drill core samples, Lake George, NSW, Australia","translated_title":"","metadata":{"abstract":"Lake George is an intermittent lake within a closed basin 40 km north of Canberra, in New South Wales, Australia.

The Lake George basin is an endorheic basin within the Southern Tablelands of Eastern Australia, bound by the Lake George Fault on the west and Palaeozoic geological units on the east. The present lake bed is about 20 km by 10 km in extent, set at an elevation of 680 metres above sea level.<br /><br />Drill core sediments have been obtained from the lake bed in the 1970’s and 1980’s by the Bureau of Mineral Resources and the Australian National University (Truswell 1984, Singh & Geissler 1985, Jacobson Jankowski and Abell 1991, etc.). From those drill cores, it was recognized that the Lake George basin contains the longest known continuous continental Quaternary sedimentary record in Australia and one of the longest in the World – an up to 165 metres sequence of sediments deposited over the last 4 million years (McEwan Mason 1991). The sedimentary sequence therefore spans the late Pliocene and the entire Quaternary Period (Pleistocene and Holocene Epochs).<br /><br />Endorheic basins are greatly affected by climate change. Pollen analyses by Singh & Geissler (1985) indicate fluctuating vegetation changes during the last 780,000 years (since the Matuyama/Brunhes paleomagnetic reversal), from subalpine grass/herbfields during glacial periods to sclerophyll woodland during interglacial periods.<br /><br />In 2015, the Australian National University obtained a new 77 m sediment core from the lake bed (GG-01), which has fewer weathering intervals and better pollen preservation than previous cores. The base of the core has an estimated age of ~2.2-2.5 million years.<br /><br />As part of the multi-disciplinary study of the core, trace fossil analysis have been carried out, based on high resolution photographs. This is the first time ever that this method has been applied to the study of Lake George sediments. Over thirty trace fossils have been found.

Drill cores obtained in the 1980's, by the Bureau of Mineral Resources (now Geoscience Australia), show that up to 165 m of sediment lies beneath the floor of the lake. A combination of magnetostratigraphy, biostratigraphy and cosmogenic nuclide burial dating indicates an age of ~4 million years (mid-Pliocene) for the base of the sedimentary sequence (Macphail et al. 2015). At present, the lake is an internally draining basin with no outlet. However, dramatic water level fluctuations have occurred during the last 200 years, largely controlled by the balance between rainfall and evaporation. At times the lake has been up several metres deep and at other times, including this year, it has been completely dry. During the Late Pleistocene, gravelly shoreline deposits indicate that the lake reached depths of 35-40 m, at which time the lake may have overflowed to the west or north, into the headwaters of either the Murrumbidgee or Lachlan rivers. The lake is impounded, on its western side, by the Lake George Fault. Quartz-rich fluvial gravels on the upthrown (western) side of the fault are more than 200 m higher than similar gravels in the base of drill holes on the downthrown side of the fault, indicating significant vertical displacement over the past 4 Ma. Palynological results from sediments dated to ~3 Ma (late Pliocene), indicate a wetland dominated by the coral fern family, Gleicheniaceae, while the surrounding dryland vegetation was a mix of sclerophyll and temperate rainforest communities, the latter including trees and shrubs whose nearest living relatives are endemic to New Guinea, New Caledonia and Tasmania; mean annual rainfall is inferred to have been 2000-3000 mm (c.f. ~600-700 mm/year today). By ~2 Ma (Early Pleistocene), rainforest species had disappeared and the dryland vegetation was sclerophyll woodland, but differing from the modern vegetation in that eucalypts were very rare; mean annual rainfall was less than 1200-1300 mm/year. The transition from the Pliocene to the Pleistocene at Lake George was therefore marked by a significant decrease in mean annual rainfall. In November 2015, we obtained a new drill core (Geary's Gap-1) from Lake George, to a depth of 77 m. Based on comparison with nearby BMR drill cores, the estimated basal age of the new core is ~2 Ma. We are undertaking detailed geochemical, mineralogical, geophysical, sedimentological, hydrological, geochronological and paleontological analyses on this core.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="af335324ad0deda1c308675c57e39f78" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":46279935,"asset_id":25920257,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/46279935/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="25920257"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="25920257"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 25920257; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=25920257]").text(description); $(".js-view-count[data-work-id=25920257]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 25920257; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='25920257']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "af335324ad0deda1c308675c57e39f78" } } $('.js-work-strip[data-work-id=25920257]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":25920257,"title":"Lake George: a sedimentary archive of the Quaternary Period","translated_title":"","metadata":{"abstract":"Lake George, at an elevation of 675 m in the Southern Highlands of NSW, contains the longest known sedimentary archive of any Australian lake basin and one of the longest in the world.

Of the nine cores collected and analyzed, contamination was detected in only 2 samples near the surface, at 430 and 860 ppm. This is the only site visit where surface contamination was not found, likely owing to the January 1999 restoration effort, where 28,000 lbs of contaminated soil was removed from the site.

When salt concentrations are high, or where some salts are sparingly soluble, the method must be expected to be problematic. This is illustrated in table 2 by some sequential extractions made on soils from both moist coastal and arid inland sites in Antarctica. Table 1. Identified salt minerals in Antarctic soils. The data is from Claridge and Campbi (1977), Campbell and Claridge (1987), Keys and Williams (1981) and Gore et al., (199! The cold water solubilities are listed (CRC 1974).

Compositions of mass of extracted salt components in different soil:water ratios, from 8 sites in the Ross Dependency. Mass extracted is mg/g soil. Ratio is of standard 1:5 (5:25) to 1:1000 extract. Total SO, was analysed as S by XRF on dry soil, and recalculated as sulphate. The use of biological, chemical and physical techniques for the remediation of contaminated soils in Antarctica are all likely to be affected by the presence of salts. For instance, the ability of the soil microorganisms to survive and metabolise is determined strictly by the presence of liquid water (Horowitz et al., 1972) rather than temperature. The tension between the availability of liquid water and the osmotic effects of the salinity of the liquid phase (e.g. Klinger and Vishniac, 1988) must be expected to play a part in the biological activity and viability of organisms in the soils. Experimental studies have shown that significant quantities of unfrozen water (~2% of the initial water remains unfrozen at temperatures as low as —70°C, Anderson and Tice, 1971, 1989) exist in Antarctic soils. This water has been shown to exist as thin (30 to 500 pm) films on soil particles, but below —5°C, the film thickness is almost invariant between 30 and 60 ym (Hoekstra 1966, Anderson 1967, Anderson and Tice 1971). The composition and properties of this water is unknown.

This extensive time span was punctuated by periods of tectonic reactivation typified by crustal heating, exhumation and cooling, and fault reactivation. Major events revealed by the results include the ~1250-1100 Ma Musgravian (Grenville) and the ~500 Ma Delamerian (Pan-African) orogenies (Fig. 2). Relatively strong tectonothermal overprints across the basement have obscured much of the early history of the Willyama Inliers. Oe te age spectra from basement samples across the three major traverses (Fig. 1) show a broad mixing of ages from ~1200-500 Ma implying that tectonometamorphic temperatures hadn’t reached higher than ~300-400°C (greenschist facies) based on retentivity in muscovite and biotite. K-feldspar data indicate that the basement, outside of shear zones, cooled to <200°C at ~630-610 Ma.

Two stages of regional cooling are recognised from AFT data (Fig. 3); the first being associated with the Alice Springs Orogeny (~300-400 Ma) and a second of smaller magnitude occurring during the Late Cretaceous to Tertiary times. A more accurate constraint on the timing and magnitude of the later cooling event comes from two boreholes in the Broken Hill Mine area which indicates ~25-30°C cooling between ~60- 20Ma. This cooling phase is possibly associated with denudation in response to intraplate stresses related to the reconfiguration of the Australian Plate and its margins during this time.

Suprisingly, many essential and desirable ingredients determined assuming epigenetic (e.g. carbonate replacement) and syngenetic models overlap. For instance, in both instances, the mineralisation should be stratiform and associated with structures. However, major differences between the models exist regarding the significance of high grade shear zones and sedimentary facies changes. Model-independent mass balance calculations indicate that large base metal accumulations such as at Broken Hill require large mineral systems. Mineral system size. The final characteristic of a mineral system with exploration implications is its size. Many world class base metal districts are characterised by a single giant deposit surrounded by many much smaller deposits. Examples of such districts include BHT deposits at Broken Hill, Sullivan and Cannington. The size of individual mineral systems may, in part, account for this distribution. Figure 1 illustrates the relationship between the size of a deposit and the size of the associated mineral system using Pb mass balance constraints. It suggests that giant deposits such as Broken Hill require large mineral systems to supply sufficient Pb. Given the constraints used to construct Figure 1 and assuming a 10% extraction efficiency, the size of the Broken Hill mineral system is on the order of 8000 km?; if a depth of 7 km is assumed for the mineral system, this translates into a surface area in excess of 1000 km”, or a square over 30 km on a side. The potential size of base metal depletion zones in albite-rich rocks from the Lady Brassey and Himalaya Formations are consistent with these calculations.

The intricate geology, including syndepositional activities and structural complexities, are explored to better understand mineral deposits and guide future mineral exploration initiatives.","conference_end_date":{"day":21,"month":10,"year":1998,"errors":{}},"conference_start_date":{"day":19,"month":10,"year":1998,"errors":{}}},"translated_abstract":null,"internal_url":"https://www.academia.edu/1765347/P_de_Caritat_B_Cruikshank_D_Gibson_S_Hill_M_Killick_N_Lavitt_%C3%89_Papp_E_Tonui_Landscape_Evolution_and_Mineral_Exploration_in_the_Broken_Hill_Region_A_New_Initiative_by_CRCLEME_1998_2002","translated_internal_url":"","created_at":"2012-07-04T19:48:06.250-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":498748,"coauthors_can_edit":true,"document_type":"conference_presentation","co_author_tags":[],"downloadable_attachments":[{"id":46396146,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/46396146/thumbnails/1.jpg","file_name":"BMR_Rec1998_025.pdf","download_url":"https://www.academia.edu/attachments/46396146/download_file","bulk_download_file_name":"P_de_Caritat_B_Cruikshank_D_Gibson_S_Hil.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/46396146/BMR_Rec1998_025-libre.pdf?1465646958=\u0026response-content-disposition=attachment%3B+filename%3DP_de_Caritat_B_Cruikshank_D_Gibson_S_Hil.pdf\u0026Expires=1744157151\u0026Signature=Ch9dUy8fDPXLgROHfKGkksSdSPRD8QYCdXoEfXAFIzCzu-lIB~mfMXPcSfYks6OYk4f4d2LP5zVPHWyXcAR9MfxJcax4afPXQ1a-0Ym0St8dm81oAT4szPIfQvrlNK9zg52bL5ZyJONEremHe7RmkMABlqeLQ2ragoBTRytUSS6GEAUeBE52UchrlebxxNV0F7poAes1rz6kC7~Bn0GKZ7Qxac89T1PPAHnKwAcF9obusaRQEIWmQa7kn92MhYvEBXA6uc7diKWgYxZ~YD5eyqm8sNpQ83euDoh42fVJeUkZB7oxR1hVnDAHiCzUQrvvNvdjKg7cubUhiMLRMR7cNA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"P_de_Caritat_B_Cruikshank_D_Gibson_S_Hill_M_Killick_N_Lavitt_É_Papp_E_Tonui_Landscape_Evolution_and_Mineral_Exploration_in_the_Broken_Hill_Region_A_New_Initiative_by_CRCLEME_1998_2002","translated_slug":"","page_count":134,"language":"en","content_type":"Work","summary":null,"impression_tracking_id":null,"owner":{"id":498748,"first_name":"Eva","middle_initials":null,"last_name":"Papp","page_name":"EvaPapp","domain_name":"anu-au","created_at":"2011-06-18T15:04:45.613-07:00","display_name":"Eva Papp","url":"https://anu-au.academia.edu/EvaPapp"},"attachments":[{"id":46396146,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/46396146/thumbnails/1.jpg","file_name":"BMR_Rec1998_025.pdf","download_url":"https://www.academia.edu/attachments/46396146/download_file","bulk_download_file_name":"P_de_Caritat_B_Cruikshank_D_Gibson_S_Hil.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/46396146/BMR_Rec1998_025-libre.pdf?1465646958=\u0026response-content-disposition=attachment%3B+filename%3DP_de_Caritat_B_Cruikshank_D_Gibson_S_Hil.pdf\u0026Expires=1744157151\u0026Signature=Ch9dUy8fDPXLgROHfKGkksSdSPRD8QYCdXoEfXAFIzCzu-lIB~mfMXPcSfYks6OYk4f4d2LP5zVPHWyXcAR9MfxJcax4afPXQ1a-0Ym0St8dm81oAT4szPIfQvrlNK9zg52bL5ZyJONEremHe7RmkMABlqeLQ2ragoBTRytUSS6GEAUeBE52UchrlebxxNV0F7poAes1rz6kC7~Bn0GKZ7Qxac89T1PPAHnKwAcF9obusaRQEIWmQa7kn92MhYvEBXA6uc7diKWgYxZ~YD5eyqm8sNpQ83euDoh42fVJeUkZB7oxR1hVnDAHiCzUQrvvNvdjKg7cubUhiMLRMR7cNA__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") if (true) { Aedu.setUpFigureCarousel('profile-work-1765347-figures'); } }); </script> <div class="js-work-strip profile--work_container" data-work-id="1767071"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" rel="nofollow" href="https://www.academia.edu/1767071/P_de_Caritat_D_Gibson_S_Hill_M_Killick_N_Lavitt_%C3%89_Papp_E_Tonui_Exploring_Australian_sedimentary_basins_for_concealed_ore_deposits_the_CRCLEME_Basins_Program"><img alt="Research paper thumbnail of P. de Caritat, D.
