| 1 | Exhuming the Meso-Cenozoic Kyrgyz Tianshan and Siberian Altai-Sayan:A review based on low-temperature thermochronology显示文摘Thermochronological datasets for the Kyrgyz Tianshan and Siberian Altai-Sayan within Central Asia reveal a punctuated exhumation history during the Meso-Cenozoic.In this paper,the datasets for both regions are collectively reviewed in order to speculate on the links between the Meso-Cenozoic exhumation of the continental Eurasian interior and the prevailing tectonic processes at the plate margins.Whereas most of the thermochronological data across both regions document late Jurassic-Cretaceous regional basement cooling,older landscape relics and dissecting fault zones throughout both regions preserve Triassic and Cenozoic events of rapid cooling,respectively.Triassic cooling is thought to reflect the Qjangtang- Eurasia collision and/or rifting/subsidence in the West Siberian basin.Alternatively,this cooling signal could be related with the terminal terrane-amalgamation of the Central Asian Orogenic Belt.For the Kygyz Tianshan,late Jurassic-Cretaceous regional exhumation and Cenozoic fault reactivations can be linked with specific tectonic events during the closure of the Palaeo-Tethys and Neo-Tethys Oceans,respectively.The effect of the progressive consumption of these oceans and the associated collisions of Cimmeria and India with Eurasia probably only had a minor effect on the exhumation of the Siberian Altai-Sayan.More likely,tectonic forces from the east(present-day coordinates) as a result of the building and collapse of the Mongol-Okhotsk orogen and rifting in the Baikal region shaped the current Siberian Altai-Sayan topography.Although many of these hypothesised links need to be tested further,they allow a first-order insight into the dynamic response and the stress propagation pathways from the Eurasian margin into the continental interior. | Stijn Glorie Johan De Grave | 2016 | Geoscience Frontiers2016，7，2： | 13 |
| 2 | Meso-Cenozoic tectonic evolution of the Talas-Fergana region of the Kyrgyz Tien Shan revealed by low-temperature basement and detrital thermochronology显示文摘This study provides new low-temperature thermochronometric data, mainly apatite fission track data on the basement rocks in and adjacent to the Talas-Fergana Fault, in the Kyrgyz Tien Shan in the first place.In the second place, we also present new detrital apatite fission track data on the Meso-Cenozoic sediments from fault related basins and surrounding intramontane basins. Our results confirm multistaged Meso-Cenozoic tectonic activity, possibly induced by the accretion of the so-called Cimmerian blocks to the Eurasian margin. New evidence for this multi-staged thermo-tectonic activity is found in the data of both basement and Meso-Cenozoic sediment samples in or close to the Talas-Fergana Fault.Zircon(U-Th)/He and apatite fission track data constrain rapid Late TriassiceE arly Jurassic and Late JurassiceE arly Cretaceous basement cooling in the Kyrgyz Tien Shan around 200 Ma and 130 -100 Ma respectively. Detrital apatite fission track results indicate a different burial history on both sides of the Talas-Fergana Fault. The apatite fission track system of the Jurassic sediments in the Middle Tien Shan unit east of the Talas-Fergana Fault is not reset, while the Jurassic sediments in the Fergana Basin and Yarkand-Fergana Basin, west of the fault zone, are partially and in some cases even totally reset. The totally reset samples exhibit Oligocene and Miocene ages and evidence the Cenozoic reactivation of the western Kyrgyz Tien Shan as a consequence of the India-Eurasia convergence. | Simon Nachtergaele Elien De Pelsmaeker Stijn Glorie Fedor Zhimulev Marc Jolivet Martin Danisík Mikhail M.Buslov Johan De Grave | 2018 | Geoscience Frontiers2018，9，5： | 4 |
| 3 | Tracking the Cretaceous transcontinental Ceduna River through Australia:The hafnium isotope record of detrital zircons from offshore southern Australia显示文摘The middle-upper Cretaceous Ceduna River system traversed continental Australia from the NE coast to the centre of the southern coast.At its mouth,it formed a vast delta system that is similar in scale to the Niger delta of West Africa.The delta system is composed of two main lobes that represent different phases of delta construction.A recent hypothesis has challenged the traditional idea that both lobes of the delta were derived from a transcontinental river system by suggesting that the upper lobe(Santonian- Maastrichtian) is instead derived from a restricted catchment within southern Australia.Hf isotopic data presented here fingerprint the original source of the upper delta lobe zircons to NE Australia,with data comparing well with similar U-Pb and Lu-Hf isotopic data from the Lachlan Orogen,the New England Orogen,the eastern Musgraves Province and the northern Flinders Ranges.These data do not preclude a model where the lobe is derived from recycled Eromanga Basin sediments during a phase of late Cretaceous inland Australian uplift,but when coupled with reconnaissance low-temperature thermochronometry from the region of the Ceduna River course indicating widespread Triassic-Jurassic exhumation,and comparisons with detrital zircon data from the Winton Formation upstream of any proposed uplift,we suggest that both lobes of the Ceduna Delta are likely to be derived from a transcontinental Ceduna River. | Jarred Lloyd Alan S.Collins Justin L.Payne Stijn Glorie Simon Holford Anthony J.Reid | 2016 | Geoscience Frontiers2016，7，2： | 2 |
| 4 | An apatite U-Pb thermal history map for the northern Gawler Craton,South Australia显示文摘Apatite U-Pb thermochronology was applied to granitoid basement samples across the northern Gawler Craton to unravel the Proterozoic, post-orogenic, cooling history and to examine the role of major fault zones during cooling. Our observations indicate that cooling following the ~2500 Ma Sleaford Orogeny and ~1700 Ma Kimban Orogeny is restricted to the Christie and Wilgena Domains of the central northern Gawler Craton. The northern Gawler Craton mainly records post-Hiltaba Event(~1590 Ma) U-Pb cooling ages. Cooling following the ~1560 Ma Kararan Orogeny is preserved within the Coober Pedy Ridge,Nawa Domain and along major shear zones within the south-western Fowler Domain. The Nawa Domain samples preserve U-Pb cooling ages that are >150 Ma younger than the samples within the Coober Pedy Ridge and Fowler Domain, indicating that later(~1300 Ma) fault movement within the Nawa Domain facilitated cooling of these samples, caused by arc collision in the Madura Province of eastern Western Australia. When compared to^(40)Ar/^(39) Ar from muscovite, biotite and hornblende, our new apatite U-Pb ages correlate well, particularly in regions of higher data density. Our data also preserve a progressive younging of U-Pb ages from the nucleus of the craton to the periphery with a stark contrast in U-Pb ages across major structures such as the Karari Shear Zone and the Southern Overthrust, which indicates the timing of reactivation of these major crustal structures. Although this interpolation was based solely on thermochronological data and did not take into account structural or other geological data, these maps are consistent with the structural architecture of the Gawler Craton and reveal the thermal footprint of known tectonic and magmatic events in the Gawler Craton. | James W.Hall Stijn Glorie Anthony J.Reid Samuel C.Boone Alan S.Collins ANDrew Gleadow | 2018 | Geoscience Frontiers2018，9，5： | 1 |
| 5 | Apatite U–Pb dating and geochemistry of the Kyrgyz South Tian Shan(Central Asia): Establishing an apatite fingerprint for provenance studies显示文摘This paper presents an apatite U-Pb and geochemistry archive for exposed plutons and metamorphic rocks of the Kyrgyz South Tian Shan(STS)within the Central Asian Orogenic Belt.Apatite U-Pb dates and trace-element geochemistry are provided for 17 samples from late Carboniferous-early Permian I-type granites in the Terktinsky complex and A-type granites in the Kokshaal Range;early Devonian granites in the Kembel complex;Cryogenian granitoids and tuffs from the Middle Tian Shan and gneisses from the Atbashi metamorphic complex.These samples form a comprehensive selection of igneous and metamorphic rocks within the cores of Mesozoic basement highs that supplied detritus to adjacent basins such as the Tarim,Ferghana and Yarkand-Ferghana Basins.Generally,the granitoid samples preserve primary igneous apatite U-Pb ages that are within uncertainty of previously published zircon U-Pb dates.The apatites from the Atbashi metamorphic complex record anomalous Ordovician dates with large uncertainties that are interpreted as mixing ages between Cryogenian protolith formation and Carboniferous metamorphism.Principal component analysis discriminates apatite samples from the different bedrock terranes in the Kyrgyz STS based on their geochemical fingerprint and categorizes the samples with respect to an extensive apatite geochemical archive.The combined apatite-zircon archive provides a novel framework for provenance studies on the Meso-Cenozoic sedimentary history of the Central Asian Orogenic Belt. | Stijn Glorie Samantha March Angus Nixon Fun Meeuws Gary J.O’Sullivan David M.Chew Christopher L.Kirkland Dmitry Konopelko Johan De Grave | 2020 | Geoscience Frontiers2020，11，6： | 1 |
| 6 | Exhuming Asia-A thermochronological perspective: Preface显示文摘Asia is the largest continent on Earth and records a prolonged history of continental growth and tectonic reactivation during the Phanerozoic.Several tectonic forces at the continental palaeomargins induced mountain building,both at the margins themselves(e.g.the Himalayas)and into the continental interior(e.g.the Tianshan).In many parts of Asia,mountain building and associated crustal exhumation/denudation are still very active as | Stijn Glorie Johan De Grave | 2016 | Geoscience Frontiers2016，7，2： | 0 |
| 7 | Laser ablation(in situ)Lu-Hf dating of magmatic fluorite and hydrothermal fluorite-bearing veins显示文摘Fluorite(CaF_(2))is a common hydrothermal mineral,which precipitates from fluorine-rich fluids with an exceptional capacity to transport metals and Rare Earth Elements(REEs).Hence,the ability to date fluorite has important implications for understanding the timing of metal transport in hydrothermal systems.Here we present,for the first time,fluorite Lu-Hf dates from fluorite-carbonate veins from the Olympic Cu-Au Province in South Australia.The fluorite dates were obtained in situ using the recently developed LA-ICP-MS/MS Lu-Hf dating method.A fluorite-calcite age of 1588±19 Ma was obtained for the Torrens Dam prospect,consistent with the timing of the formation of the nearby Olympic Dam iron-oxide copper gold Breccia Complex.Veins in the overlying Neoproterozoic successions were dated at 502±14 Ma,indicating a temporal link between Cu-sulphide remobilisation and the Delamerian Orogeny.Additionally,we present a multi-session reproducible date for magmatic fluorite from a monzogranite in the Pilbara Craton(Lu-Hf age of 2866±19 Ma).This age is consistent with a garnet Lu-Hf age from the same sample(2850±12 Ma)and holds potential to be developed into a secondary reference material for future fluorite Lu-Hf dating. | Stijn Glorie Jacob Mulder Martin Hand Adrian Fabris Alexander Simpson Sarah Gilbert | 2023 | Geoscience Frontiers2023，14，6： | 0 |
| 8 | Neoproterozoic tectonic geography of the south-east Congo Craton in Zambia as deduced from the age and composition of detrital zircons显示文摘The Southern Irumide Belt(SIB)is an orogenic belt consisting of a number of lithologically varied Mesoproterozoic and Neoproterozoic terranes that were thrust upon each other.The belt lies along the southwest margin of the Archaean to Proterozoic Congo Craton,and bears a Neoproterozoic tectonothermal overprint relating to the Neoproterozoic-Cambrian collision between the Congo and Kalahari cratons.It preserves a record of about 500 million years of plate interaction along this part of the Congo margin.Detrital zircon samples from the SIB were analysed for U-Pb and Lu-Hf isotopes,as well as trace element compositions.These data are used to constrain sediment-source relationships between SIB terranes and other Gondwanan terranes such as the local Congo Craton and Irumide belt and wider afield to Madagascar(Azania)and India.These correlations are then used to interpret the Mesoproterozoic to Neoproterozoic affinity of the rocks and evolution of the region.Detrital zircon samples from the Chewore-Rufunsa and Kacholola(previously referred to as Luangwa-Nyimba)terranes of the SIB yield zircon U-Pb age populations and evolvedε(Hf)(t)values that are similar to the Muva Supergroup found throughout eastern Zambia,primarily correlating with Ubendian-Usagaran(ca.2.05-1.80 Ga)phase magmatism and a cryptic basement terrane that has been suggested to underlie the Bangweulu Block and Irumide Belt.These data suggest that the SIB was depositionally connected to the Congo Craton throughout the Mesoproterozoic.The more eastern Nyimba-Sinda terrane of the SIB(previously referred to as Petauke-Sinda terrane)records detrital zircon ages andε(Hf)(t)values that correlate with ca.1.1-1.0 Ga magmatism exposed elsewhere in the SIB and Irumide Belt.We ascribe this difference in age populations to the polyphase development of the province,where the sedimentary and volcanic rocks of the Nyimba-Sinda terrane accumulated in extensional basins that developed in the Neoproterozoic.Such deposition would have occurred following late-Mesoproterozoic magmatism that is widespread throughout both the Irumide and Southern Irumide Belts,presently considered to have occurred in response to collision between a possible microcontinental mass and the Irumide Belt.This interpretation implies a multi-staged evolution of the ocean south of the Congo Craton during the mid-Mesoproterozoic to late-Neoproterozoic,which ultimately closed during collision between the Congo and Kalahari cratons. | Brandon L.Alessio Alan S.Collins Peter Siegfried Stijn Glorie Bert De Waele Justin Payne Donnelly B.Archibald | 2019 | Geoscience Frontiers2019，10，6： | 0 |
| 9 | In situ Lu–Hf phosphate geochronology:Progress towards a new tool for space exploration显示文摘Geochronology is fundamental to understanding planetary evolution.However,as space exploration continues to expand,traditional dating methods,involving complex laboratory processes,are generally not realistic for unmanned space applications.Campaign-style planetary exploration missions require dating methods that can(1)rapidly resolve age information on small samples,(2)be applied to minerals common in mafic rocks,and(3)be based on technologies that could be installed on future rover systems.We demonstrate the application of rapid in situ microanalytical Lu–Hf phosphate geochronology using samples of pallasite meteorites,which are representative examples of the deep interiors of differentiated planetoids that are generally difficult to date.Individual pallasites were dated by laser ablation tandem mass-spectrometry(LA-ICP-MS/MS),demonstrating a rapid novel method for exploring planetary evolution.Derived formation ages for individual pallasites agree with traditional methods and have<2%uncertainty,opening an avenue of opportunity for remote micro-analytical space exploration. | Stijn Glorie Thomas Burke Martin Hand Alexander Simpson Sarah Gilbert Benjamin Wade | 2022 | Geoscience Frontiers2022，13，3： | 0 |
| 10 | Cenozoic low temperature cooling history of the eastern Lhasa terrane:Implications for high-relief topography of external drainage area in the southern Tibetan Plateau显示文摘The Tibetan Plateau geographically contains internal and external drainage areas based on the distributions of river flows and catchments.The internal and external drainage areas display similar highelevations,while their topographic reliefs are not comparable;the former shows a large low-relief surface,whereas the latter is characterized by relatively high relief.The eastern Lhasa terrane is a key tectonic component of the Tibetan Plateau.It is characterized by high topography and relief,but the thermal history of its basement remains relatively poorly constrained.In this study we report new apatite fission track data from the eastern part of the central Lhasa terrane to constrain the thermo-tectonic evolution of the external drainage area in the southern Tibetan Plateau.Twenty-one new AFT ages and associated thermal history models reveal that the basement underlying the external drainage area in southern Tibet experienced three main phases of rapid cooling in the Cenozoic.The Paleocene-early Eocene(-60–48 Ma)cooling was likely induced by crustal shortening and associated rock exhumation,due to accelerated northward subduction of the NeoTethys oceanic lithosphere.A subsequent cooling pulse lasted from the late Eocene to early Oligocene(-40–28 Ma),possibly due to the thickening and consequential erosion of the Lhasa lithosphere resulted from the continuous northward indentation of the India plate into Eurasia.The most recent rapid cooling event occurred in the middle Miocene-early Pliocene(-16–4 Ma),likely induced by accelerated incision of the Lhasa River and local thrust faulting.Our AFT ages and published low-temperature thermochronological data reveal that the external drainage area experienced younger cooling events compared with the internal drainage area,and that the associated differentiated topographic evolution initiated at ca.30 Ma.The contributing factors for the formation of the high-relief topography mainly contain active surface uplift,fault activity,and the enhanced incision of the Yarlung River. | Wenbo Su Zhiyuan He Linglin Zhong Stijn Glorie Kanghui Zhong Johan De Grave | 2023 | Geoscience Frontiers2023，14，5： | 0 |
