The Tibetan Plateau(TP) is a regional Earth system showing very strong interactions among its lithosphere, hydrosphere, cryosphere, biosphere, atmosphere, and anthrosphere. hese interactions manifest TP’s impact on surrounding regions and relect TP’s response to the global change. Quantifying the multispherical interactions is critically important to understand the TP environment. Our recent years researches including the ongoing program entitled ‘Tibetan Multi-Spheres Interactions and heir Resource-Environment Signiicance(TIMI)’, the completed program entitled. ‘Paleo-Altitudes of Tibetan Plateau and Environment(PATE)’, as well as the other relating projects have focused on multidisciplinary research approaches and emphasized on three major pathways: Eurasia-Indian plates collision on deep-Earth dynamics, uplit impact on Earth’s mantle–crust dynamics, and contemporary interface on land surface and atmospheric dynamics. Our researches have taken in situ measurement as priority and developed several platforms of data acquisition and analysis, including the platforms of water-phase transformations, and ecosystem observations. Our ield investigations have been conducted to obtain data about stratum, paleontology, paleoenvironment, genetic diferentiation of animals and plants. We have developed conceptual and mathematical models for crust uplit formation, paleoclimate, glacial melt,water–air interface lux, vegetation climate, and soil erosion. We have also assessed the anthropogenic impacts on environment. Our researches have achieved new and reliable redating of the mantle–crust interaction and initial formation of the TP, found the interaction between tectonics and uplit of the TP and resultant paleoaltitude acting as a spreading source; discovered the interaction between the westerlies and Indian monsoon acting as a control chain that dominates the TP’s contemporary environment. he scientiic results can play fundamental roles in supporting the TP’s resource explorati

Geochronological Significance of the Post-Orogenic Mafic-Ultramafic Rocks in the Hongqiling Area of Jilin Province, Northeast China

引用

Earthquake Research in China 2006年第2期20卷 216-224页

作者： Zhang Guangliang wu fuyuan Institute of Geology China Earthquake Administration Beijing 100029 China Institute of Geology and Geophysics Chinese Academy of Sciences Beijing 100029 China

Mafic-uitramafic complexes are widespread in Hongqiling in central Jiulin Province, NE China. The Hongqiling complex comprises pyroxenite, olivine websterite, lberzolite, gabbro and leucogabbro. Based on the latest geochronological results, these intrusions yield a zircon U-Pb age of about 216 Ma, implying that they emplaced in the late Triassic period and that the mafic-uitramafic complexes are post-orogenic in origin. These ages are coeval with the emplacement of A-type granites in the area, but slightly younger than syn-orogenic granitic magmatism. The composition of the parent magma during the equilibration of the accumulated olivine crystallizing is basaltic with high MgO, and it comes from depleted or juvenile lithospheric mantle, according to the results of trace elements and Sr-Nd isotopes. Amount of crustal material contaminated the magmatic source, implying that the mafic-uitramafic rocks originate from the mixing product of crust- and mantle-derived magma. Therefore, the magmatic source was contaminated by an amount of crustal material, and the subsequent crystal fractionation resulted in the Cu-Ni mineralization. Dynamic analyses indicate that, after the collision of the North China Craton and Jiamusi Massif, the lithospheric delamination during post-orogeny resulted in the upwelling of asthenosphere and the intruding of the mass and underplating of the mantle-derived magma, which led to the formation of the primary mafic-uitramafic magma due to the mantle-derived magma and partial melting of the lower crust. This result suggests that the mafic-uitramafic complexes belong to a typically important magmatic suite that evolved during post-orogenic processes, and they were exposed as maficultramafic dyke swarms that existed in the post-orogenic extension environment. It also implies that the orogenic process finished ultimately in this regional geological setting. The widespread occurrence of mafic-uitramafic complexes in the Xing＇an-Mongolia Orogenic Belt i

Age and nature of the Budate Group in the Hailar Basin are of great significance in studying the evolution of the Hailar Basin and the Xing'an-Mongolian Orogenic Belt(XMOB).Zircon U-Pb ages of eight volcanic rocks from the Budate Group and two basement granites in the Hailar Basin were reported in this *** dating results indicated that the formation of these volcanic rocks was consistent with the emplacement of Late Paleozoic basement granite in age(356-290 Ma),i.e.,Early Carboniferous to Early Permian rather than Early *** with regional geology,it was concluded that the Budate Group is the component of the basement of the Hailar Basin,and these volcanic rocks were formed at an active continental margin,which is related to the closure of the Hegen Mountains suture *** captured Neoproterozoic zircons(814-873 Ma) were probably derived from the Neoproterozoic basement materials in the Ergun Block,implying the close genetic relationships between the Ergun Block(including the Hailar Basin) and the Siberian Block.

Early Paleozoic ridge subduction in the Chinese Altai: Insight from the abrupt change in zircon Hf isotopic compositions

引用

Science China Earth Sciences 2009年第7期52卷 1345-1358页

作者： SUN Min LONG XiaoPing CAI KeDa JIANG YingDe WANG BuYun YUAN Chao ZHAO GuoChun XIAO WenJiao wu fuyuan Department of Earth Sciences The University of Hong KongPokfulam RoadHong KongChina Key Laboratory of Isotope Geochronology and Geochemistry Guangzhou Institute of GeochemistryChinese Academy of SciencesGuangzhou 510640China State Key Laboratory of Lithospheric Evolution Institute of Geology and GeophysicsChinese Academy of SciencesBeijing 100029China

Zircons were separated from granitoids, gneisses, and sedimentary rocks of the Chinese Altai. Those with igneous characteristics yielded U-Pb ages of 280-2800 Ma, recording a long history of magmatic activity in the region. Zircon Hf isotopic compositions show an abrupt change at ~420 Ma, indicating that prior to that time the magmas came from both ancient and juvenile sources, whereas younger magmas were derived mainly from juvenile material. This may imply that the lithosphere was signifi- cantly modified in composition by a rapid addition of melt from the mantle. We suggest that this dramatic change was due to the onset of ridge subduction, which can account not only for the formation of voluminous granitoids, mafic rocks with complex compositions, and the association of adakite + high-Mg andesite + boninite + Nb-enriched basalt, but also for the coeval high-T, low-P metamorphism.

Numerical studies on the radiation uniformity of Z-pinch dynamic hohlraum

Matter and Radiation at Extremes 2018年第5期3卷 248-255页

Radiation uniformity is important for Z-pinch dynamic hohlraum driven fusion. In order to understand the radiation uniformity of Z-pinchdynamic hohlraum, the code MULTI-2D with a new developed magnetic field package is employed to investigate the related physical processeson Julong-I facility with drive current about 7e8 MA. Numerical simulations suggest that Z-pinch dynamic hohlraum with radiation temperaturemore than 100 eV can be created on Julong-I facility. Although some X-rays can escape out of the hohlraum from Z-pinch plasma and electrodes, the radiation field near the foam center is quite uniform after a transition time. For the load parameters used in this paper, the transitiontime for the thermal wave transports from r = 1 mm to r = 0 mm is about 2.0 ns. Implosion of a testing pellet driven by cylindrical dynamichohlraum shows that symmetrical implosion is hard to achieve due to the relatively slow propagation speed of thermal wave and the compressionof cylindrical shock in the foam. With the help of quasi-spherical implosion, the hohlraum radiation uniformity and corresponding pelletimplosion symmetry can be significantly improved thanks to the shape modulation of thermal wave front and shock wave front.

中国科学院地质与地球物理研究所博物馆珍藏一件阿波罗(Apollo)月壤样品,但其身世一直不清。根据获得的颗粒组成、形貌、粒度及成分等多方面资料,它属于阿波罗11号样品无疑,确切的样品编号应该是10084。推测该样品可能是1971年春季“乒乓外交”时期,美国政府赠送给中国的礼品。通过进一步的梳理发现,我国目前保存有多件阿波罗月球样品。具体包括中国科学院地质与地球物理研究所博物馆的阿波罗11号(10084)、中国台中自然博物馆的阿波罗11号(10085)、中国国家博物馆的阿波罗12号(12001或12070)和北京天文馆的阿波罗17号(70017),以及浙江省和上海市可能保存的阿波罗15号。目前不排除在民间或其它机构,有少量其它月球样品的保存。这些样品是20世纪70年代中美两国外交关系发展的见证,具有重要的史料价值。结合我国嫦娥五号返回的样品,这些月球样品对我国科学家研究月球的形成演化提供了极为重要的参考对象,因而也具有重大的科研价值。
