1新疆伊犁北部石炭纪火山岩地球化学特征及其地质意义显示文摘石炭纪火山岩广泛分布于西天山伊犁陆块周缘,其岩性复杂,并大多与陆源碎屑岩伴生或互层。其中伊宁阿希、尼勒克和那拉提3个剖面的火山岩岩石地球化学特征显示,这些火山岩属于钙碱性系列,由玄武岩、粗玄岩、玄武质安山岩、玄武质粗面安山岩、安山岩、流纹岩、英安岩和粗面岩组成。稀土元素含量较高,轻稀土元素较重稀土元素富集。这些火山岩亏损高场强元素Nb,Ta,Zr等,而富集大离子亲石元素Th,Rb等,因而这些岩石的形成与板块俯冲有关。微量元素地球化学图解进一步表明,这些岩石形成于大陆岛弧环境。与之共生的早、中石炭世浅海—滨海相沉积地层以及伊犁陆块北缘巴音沟—莫托沙拉沟晚泥盆世—早石炭世蛇绿岩带的存在,表明伊犁陆块北缘在石炭纪时其环境为活动大陆边缘,石炭纪火山岩的形成可能与晚泥盆世—中石炭世早期北天山洋盆向南的俯冲作用有关。王博 舒良树 Cluzel D Faure M Charvet J 马前 2006中国地质2006,33,3:62
2Palaeozoic tectonic evolution of the Tianshan belt,NW China显示文摘The Chinese Tianshan belt is a major part of the southern Central Asian Orogenic Belt,extending westward to Kyrgyzstan and Kazakhstan.Its Paleozoic tectonic evolution,crucial for understanding the amalgamation of Central Asia,comprises two stages of subduction-collision.The first collisional stage built the Eo-Tianshan Mountains,before a Visean unconformity,in which all structures are verging north.It implied a southward subduction of the Central Tianshan Ocean beneath the Tarim active margin,that induced the Ordovician-Early Devonian Central Tianshan arc,to the south of which the South Tianshan back-arc basin opened.During the Late Devonian,the closure of this ocean led to a collision between Central Tianshan arc and the Kazakhstan-Yili-North Tianshan Block,and subsequently closure of the South Tianhan back-arc basin,producing two suture zones,namely the Central Tianshan and South Tianshan suture zones where ophiolitic mélanges and HP metamorphic rocks were emplaced northward.The second stage included the Late Devonian-Carboniferous southward subduction of North Tianshan Ocean beneath the Eo-Tianshan active margin,underlined by the Yili-North Tianshan arc,leading to the collision between the Kazakhstan-Yili-NTS plate and an inferred Junggar Block at Late Carboniferous-Early Permian time.The North Tianshan Suture Zone underlines likely the last oceanic closure of Central Asia Orogenic Belt;all the oceanic domains were consumed before the Middle Permian.The amalgamated units were affected by a Permian major wrenching,dextral in the Tianshan.The correlation with the Kazakh and Kyrgyz Tianshan is clarified.The Kyrgyz South Tianshan is equivalent to the whole part of Chinese Tianshan(CTS and STS) located to the south of Narat Fault and Main Tianshan Shear Zone;the so-called Middle Tianshan thins out toward the east.The South Tianshan Suture of Kyrgyzstan correlates with the Central Tianshan Suture of Chinese Tianshan.The evolution of this southern domain remains similar from east(Gangou area) to west until the Talas-Ferghana Fault,which reflects the convergence history between the Kazakhstan and Tarim blocks.Jacques CHARVET SHU LiangShu Sebastien LAURENT-CHARVET WANG Bo Michel FAURE Dominique CLUZEL CHEN Yan Koen De JONG 2011Science China Earth Sciences2011,54,2:57
3伊犁北部博罗霍努岩体年代学和地球化学研究及其大地构造意义显示文摘博罗霍努岩体是发育在新疆伊犁北部的一个大型海西期花岗岩体,总体沿近 SE—NW 向分布,出露面积逾2000km^2。该岩体主要包括三类花岗岩:灰黑色辉石闪长岩、浅色黑云母花岗岩和紫红色黑云母钾长花岗岩。锆石 U—Pb La-ICP-MS 定年表明,辉石闪长岩的年龄为301±7Ma,黑云母花岗岩的年龄范围为294±7~285±7Ma,而黑云母钾长花岗岩则形成于280±5~266±6Ma。岩石地球化学分析显示,黑云母花岗岩和钾长花岗岩以准铝或弱过铝Ⅰ型花岗岩为主,个别属于弱过铝 S 型花岗岩。在微量元素方面,这些花岗岩均富集轻稀土而亏损重稀土,但来自两个剖面的花岗岩具有不同的稀土元素配分模式,可能代表它们的岩浆源区有所不同,因此需要进一步对这些花岗岩进行同位素地质学研究。相对于洋脊花岗岩而言,博罗霍努岩体的花岗岩明显富集 K,Rb,Ba 和 Th,同时,显著亏损 Nb,Ta,Y 和 Yh。以上地球化学特征及微量元素判别图表明,这些花岗岩类形成于俯冲有关的火山岛弧环境。结合伊犁及邻区岩浆岩的特征及其时代,可以认为博罗霍努岩体的形成与天山北部洋壳向南的俯冲造山作用有关。西天山北部俯冲造山作用最终在中二叠世结束,并在中一晚二叠世进入陆内造山和伸展拉张阶段。王博 舒良树 Dominique CLUZEL Michel FAURE Jacques CHARVET 2007岩石学报2007,23,8:40
4科克苏-穹库什太古生代构造-岩浆作用及其对西南天山造山时代的约束显示文摘天山造山带是古生代多期碰撞增生作用的产物,其确切的造山时代是当前争议较多的热点问题。分布在西南天山的科克苏-穹库什太剖面经历了复杂的构造变形,最明显的两期变形事件分别为朝北的推覆作用和 NE-SW 韧性走滑作用。本剖面可分为伊犁岩浆岛弧、伊犁结晶基底、高压变质杂岩三个岩石-构造单元。野外可见黑云母花岗闪长岩侵入到绿片岩相变质岩中,岩脉切穿绿片岩中面理构造。通过锆石 U-Pb LA-ICPMS 测年,科克苏剖面钾长花岗岩的年龄为341±6Ma 和338±8Ma,穹库什太黑云母花岗闪长岩的年龄为313±4Ma。其中,花岗闪长岩发生了黑云母定向排列,通过对黑云母进行^(40)Ar/^(39)Ar 测年,获得坪年龄为263.4±0.6Ma,表明该花岗闪长岩受过后期热事件的干扰。地球化学分析表明,黑云母花岗闪长岩属于钙碱性系列,Nb 和 Ta 含量低而 Rb,Ba 和 Th 含量很高,与俯冲作用有关的岛弧岩浆岩地球化学组成非常相似。结合前人对该地区高压变质岩、花岗岩和火山岩的研究成果,本文提出,西南天山俯冲-碰撞造山作用发生在晚石炭世之前,研究区后碰撞区域走滑作用标志着西南天山碰撞造山作用在二叠纪之前全部结束。王博 舒良树 MichelFAURE DominiqueCLUZEL JacquesCHARVET Michel FAURE Dominique CLUZEL Jacques CHARVET 2007岩石学报2007,23,6:25
5Toward a unified model of Altaids geodynamics:Insight from the Palaeozoic polycyclic evolution of West Junggar(NW China)显示文摘The Altaid tectonic collage extends over Central Asia, exposing numerous accretionary orogens that can account for the Palaeozoic continental crust growth. A pluridisciplinary approach, using geochronological, geochemical, structural and palaeomagnetic tools was carried out to unravel the architecture and the evolution of West Junggar(Northwestern China), a segment of the Altaid Collage. A polycyclic geodynamic evolution is inferred and includes:(1) an Early Palaeozoic cycle, characterized by the closure of two oceanic basins bounded by island-arc systems;(2) an Early Devonian subduction jamming resulting in a minor-scale collision documented by thrusting, syntectonic sedimentation and subsequent crutal thinning associated with alkaline magmatism;(3) a Late Palaeozoic cycle, driven by the evolution of two opposite subduction zones developed upon the Early Palaeozoic basement. Detailed structural analysis and paleomagnetic data provide constraints for the late evolution of Junggar in the frame of the development of the Late Palaeozoic Kazakh orocline, which led to oblique subduction and transpression in the West Junggar accretionary complex. Progressive buckling of the Kazakh orocline further resulted in Late Carboniferous to Permian wrench tectonics, and lateral displacement of lithotectonic units. Block rotations that continued after the Late Triassic are due to diachronous intraplate reactivation. This scenario mirrors the Palaeozoic geodynamics of the Altaid Collage. Multiple Early Palaeozoic collisions of intra-oceanic arcs and micro continents have contributed to the formation of the Kazakhstan Microcontinent. Since the Late Palaeozoic, subductions formed around this microcontinent and the final oblique closure of oceanic domains resulted in the transcurrent collage of Tarim and Siberia cratons. Palaeozoic strike-slip faults were later reactivated during Mesozoic intracontinental tectonics.Flavien CHOULET Michel FAURE Dominique CLUZEL CHEN Yan LIN Wei WANG Bo XU Bei 2016Science China Earth Sciences2016,59,1:6
6Saturable plasmonic metasurfaces for laser mode locking显示文摘Metamaterials are artificial materials made of subwavelength elementary cells that give rise to unexpected wave properties that do not exist naturally.However,these properties are generally achieved due to 3D patterning,which is hardly feasible at short wavelengths in the visible and near-infrared regions targeted by most photonic applications.To overcome this limitation,metasurfaces,which are the 2D counterparts of metamaterials,have emerged as promising platforms that are compatible with planar nanotechnologies and thus mass production,which platforms the properties of a metamaterial into a 2D sheet.In the linear regime,wavefront manipulation for lensing,holography,and polarization control has been achieved recently.Interest in metasurfaces operating in the nonlinear regime has also increased due to the ability of metasurfaces to efficiently convert incident light into harmonic frequencies with unusual polarization properties.However,to date,the nonlinear absorption of metasurfaces has been mostly ignored.Here,we demonstrate that plasmonic metasurfaces behave as saturable absorbers with modulation performances superior to the modulation performance of other 2D materials and exhibit unusual polarimetric nonlinear transfer functions.We quantify the link between saturable absorption,the plasmonic resonances of the unit cell and their distribution in a 2D metasurface,and finally provide a practical implementation by integrating the metasurfaces into a fiber laser cavity operating in pulsed regimes driven by the metasurface properties.As such,this work provides new perspectives on ultrathin nonlinear saturable absorbers for applications where tunable nonlinear transfer functions are needed,such as in ultrafast lasers or neuromorphic circuits.Jiyong Wang Aurelien Coillet Olivier Demichel Zhiqiang Wang Davi Rego Alexandre Bouhelier Philippe Grelu Benoit Cluzel 2020Light(Science & Applications)2020,9,1:3
7南朝鲜沃川带的地球动力学显示文摘在东亚活动边缘的外缘,中朝克拉通被显生宙活动带划分为几个断块(图1A)。迄今为止,除地台域外,对该区前二叠纪地球动力学演化研究甚少。特别是南朝鲜沃川带的无化石变质沉积岩(沃川超群)的时代及其构造背景是争论的焦点。根据朝鲜地质学家以往的填图,自1985年起,本文作者之一D.D. Cluzel 丁宇 1991海洋地质译丛1991,,4:3

20Sr,Nd,Pb and trace element systematics of the New Caledonia harzburgites:Tracking source depletion and contamination processes in a SSZ setting显示文摘The New Caledonia ophiolite(Peridotite Nappe)consists primarily of harzburgites,locally overlain by mafic-ultramafic cumulates,and minor spinel and plagioclase lherzolites.In this study,a comprehensive geochemical data set(major and trace element,Sr-Nd-Pb isotopes)has been obtained on a new set of fresh harzburgites in order to track the processes recorded by this mantle section and its evolution.The studied harzburgites are low-strain tectonites showing porphyroclastic textures,locally grading into protomylonitic textures.They exhibit a refractory nature,as attested by the notable absence of primary clinopyroxene,very high Fo content of olivine(91-93 mol.%),high Mg#of orthopyroxene(0.91-0.93)and high Cr#of spinel(0.44-0.71).The harzburgites are characterised by remarkably low REE concentrations(<0.1 chondritic values)and display'U-shaped'profiles,with steeply sloping HREE(DyN/YbN=0.07-0.16)and fractionated LREE-MREE segments(LaN/SmN=2.1-8.3),in the range of modern fore-arc peridotites.Geochemical modelling shows that the HREE composition of the harzburgites can be reproduced by multi-stage melting including a first phase of melt depletion in dry conditions(15%fractional melting),followed by hydrous melting in a subduction zone setting(up to 15%-18%).However,melting models fail to explain the enrichments observed for some FME(i.e.Ba,Sr,Pb),LREE-MREE and Zr-Hf.These enrichments,coupled with the frequent occurrence of thin,undeformed films of Al2 O3,and CaO-poor orthopyroxene(Al2O3=0.88-1.53 wt.%,CaO=0.31-0.56 wt.%)and clinopyroxene with low Na2 O(0.03-0.16 wt.%),Al2 O3(0.66-1.35 wt.%)and TiO2(0.04-0.10 wt.%)contents,point to FME addition during fluid-assisted melting followed by late stage metasomatism most likely operated by subductionrelated melts with a depleted trace element signature.Nd isotopic ratios range from unradiogenic to radiogenic(-0.80<εNdi≤+13.32)and negatively correlate with Sr isotopes(0.70257≤87Sr/86Sr≤0.70770).Pb isotopes cover a wide range,trending from DMM toward enriched,sediment-like,compositions.We interpret the geochemical signature displayed by the New Caledonia harzburgites as reflecting the evolution of a highly depleted fore-arc mantle wedge variably modified by different fluid and melt inputs during Eocene subduction.Arianna Secchiari Alessandra Montanini Delphine Bosch Patrizia Macera Dominique Cluzel 2020Geoscience Frontiers2020,11,1:1
