2Late Jurassic-Early Cretaceous Plutonism in the Northern Part of the Precambrian North China Craton:SHRIMP Zircon U-Pb Dating of Diorites and Granites from the Yunmengshan Geopark,Beijing显示文摘The Yunmengshan Geopark in northern Beijing is located within the Yanshan range.It contains the Yunmengshan batholith,which is dominated by two plutons:the Yunmengshan gneissic granite and the Shicheng gneissic diorite.Four samples of the Yunmengshan gneissic granite give SHRIMP zircon U-Pb ages from 145 to 141 Ma,whereas four samples of the Shicheng gneissic diorite have ages from 159 Ma to 151 Ma.Dikes that cut the Yunmengshan diorite record SHRIMP zircon UPb age of 162±2 and 156±4 Ma.The cumulative plots of zircons from the diorites show a peak age of 155 Ma,without inherited zircon cores,and the peak age of 142 Ma for granite is interpreted as the emplacement age of the Yunmengshan granitic pluton,whose igneous zircons contain inherited zircon cores.The data presented here show that there were two pulses of magmatism:early diorites,followed c13 Ma later by true granites,which incorporated material from an older continental crust.SHI Yuruo ZHAO Xitao MA Yinsheng HU Daogong LIU Qisheng WU Zhenhan ZHAO Yuanyi LIU Dunyi 2009Acta Geologica Sinica(English Edition)2009,83,2:17

4Late Quaternary normal faulting and its kinematic mechanism of eastern piedmont fault of the Haba-Yulong Snow Mountains in northwestern Yunnan, China显示文摘The regional geologic and geomorphic observations show that an active arcuate normal fault constitutes the main boundary fault of the Haba-Yulong Snow Mountains (HYSM). This fault is called eastern piedmont fault of Haba-Yulong Snow Mountains (HYPF). The fault consists of two segments with differential trend; the northern segment is NW-trending and NE-dipping and the southern section is S-N trending and E-dipping. Three sets of fault scarps cutting late Quaternary landforms and their dating results indicate that the fault is a prominent Holocene active fault and its throw rates are 0.3―1.4 mm/a during late Quaternary. The geometry and kinematics of the fault suggest that the arcuate normal faulting or rifting are typical surface deformation pattern at the two tips of the Z-shaped rift zone of northwestern Yunnan, which is related to regional east-west extension accompanying clockwise rota- tion of micro-block.WU ZhongHai ZHANG YongShuang HU DaoGong ZHAO XiTao YE PeiSheng 2009Science China Earth Sciences2009,52,10:14
5Early Cenozoic Tectonics of the Tibetan Plateau显示文摘Geological mapping at a scale of 1:250000 coupled with related researches in recent years reveal well Early Cenozoic paleo-tectonic evolution of the Tibetan Plateau. Marine deposits and foraminifera assemblages indicate that the Tethys-Himalaya Ocean and the Southwest Tarim Sea existed in the south and north of the Tibetan Plateau, respectively, in Paleocene-Eocene. The paleooceanic plate between the Indian continental plate and the Lhasa block had been as wide as 900km at beginning of the Cenozoic Era. Late Paleocene transgressions of the paleo-sea led to the formation of paleo-bays in the southern Lhasa block. Northward subduction of the Tethys-Himalaya Oceanic Plate caused magma emplacement and volcanic eruptions of the Linzizong Group in 64.5-44.3 Ma, which formed the Paleocene-Eocene Gangdise Magmatic Arc in the north of Yalung-Zangbu Suture (YZS), accompanied by intensive thrust in the Lhasa, Qiangtang, Hoh Xil and Kunlun blocks. The Paleocene-Eocene depression of basins reached to a depth of 3500-4800 m along major thrust faults and 680-850 m along the boundary normal faults in central Tibetan Plateau, and the Paleocene-Eocene depression of the Tarim and Qaidam basins without evident contractions were only as deep as 300-580 m and 600-830 m, respectively, far away from central Tibetan Plateau. Low elevation plains formed in the southern continental margin of the Tethy-Himalaya Ocean, the central Tibet and the Tarim basin in Paleocene-Early Eocene. The Tibetan Plateau and Himalaya Mts. mainly uplifted after the Indian-Eurasian continental collision in Early-Middle Eocene.WU Zhenhan HU Daogong YE Peisheng WU Zhonghai 2013Acta Geologica Sinica(English Edition)2013,87,2:9
6Quantitative Zoning Assessment of Crustal Stability Along the Yunnan-Tibet Railway Line,Western China显示文摘The planned Yunnan-Tibet railway goes through the northwest of Yunnan Province and the southeast of the Tibet Autonomous Region.Because of its location near the collision belt of the Eurasian and Indian plates,complex engineering geological conditions and difficult engineering geological problems are encountered.The study is aimed at making the zoning assessment of crustal stability along the railway line so as to provide a better base for its construction,especially its line selection.For this purpose,the following seven influencing factors of crustal stability were selected and quantified by grading and scoring:active fault,seismic activity,geo-stress field,geo-strain field, geothermal field,geo-hazard,and lithologic character.Of these factors,the active fault,seismic activity and geo-hazard are the three most prominent factors influencing the railway construction.Along the railway line there are 1731703 calculation units to be divided.The zoning assessment calculation was completed by ArcGIS-based information fusion method.The assessment results aid railway line selection and show that there are 10 stable sectors,28 relatively stable sectors,23 relatively unstable sectors,and 20 unstable sectors along the Yunnan-Tibet railway line.ZHANG Yongshuang YAO Xin HU Daogong GUO Changbao XIONG Tanyu 2012Acta Geologica Sinica(English Edition)2012,86,4:9

8Zircon SHRIMP U-Pb Dating, Geochemical Characteristics and Tectonic Significance of Granitic Gneisses in Amdo, Tibet显示文摘The Amdo microcontinent is located within the middle of Bangong-Nujiang suture(BNS) zone in the shape of lens. The basic geological research restricts geologists from understanding the histories of tectonic evolution of BNS and regional geology more deeply. This paper systematically studies the geochronology and geochemistry of granitic gneisses from Amdo basement. These data provide constraints on formation age, source characteristics and tectonic setting of their protolith. The SHRIMP zircon U-Pb dating is operated for granitic gneisses. Samples AGS-2 and AGS-3(granitic gneiss) yield average zircon U-Pb ages of 485±14 and 487±6 Ma, respectively. These ages should represent the formation age of protolith and indicate that they are formed in the Early Ordovician. Granitic gneisses are characterized by high SiO2, Na2O, K2O and Al2O3, low Fe and Mg, enrichment in light rare earth elements(LREEs) and large ion lithophile elements(LILEs), depletion in heavy rare earth elements(HREEs) and high field strength elements(HFSEs), with negative Eu anomaly. The Rittmann index(σ) is 1.77 to 2.60, less than 3.3. The aluminum saturation index(A/CNK) values range from 0.88 to 1.26. These features suggest that protolith of granitic gneisses from Amdo basement show characteristics of calc-alkaline and S-type granite, and they could be derived from partial melting of metamorphic greywackes in the upper crust of low maturity. The tectonic setting is syn-collision. These all suggest that the formation of protolith of granitic gneisses from Amdo are caused by the Early Paleozoic orogeny, which could be related to proto-Tethyan oceanic subduction along Gondwana continental margins, and does not result from the production of Pan-African orogenesis.Lu Lu Zhenhan Wu Zhen Zhao Daogong Hu Peisheng Ye 2014Journal of Earth Science2014,25,3:3

20The variety of thermal conduction resulting from segmented degree of heat source body and its bearing on temperature change显示文摘The differences of thermal conduction and its temperature-varying track of the heat source body at various structural environments have been studied. Hypothetically, geologic heat source body is cut successively into several segregative bodies with a fixed cubage. With the segmented number increasing, the conductive surface area of heat source body begins to get larger, which separately is similar to the heat geologic body in different tectonic zones that has a various enclosed coefficient η(η=S0/sum from i=(1,n)(Si)). Finite-element simulation result shows that the thermal conduction speed of spreading from the heat source body to its wall rock is slow→higher→highest, when heat source bodies are situated respectively at compressive, shear and tensile deformation zones, corresponding rates of their temperature drop are low→higher→highest. Research indicates that the temperature’s dropping rate of heat source body has an inverse relationship with enclosed coefficient η for different structuralGuxian Lü Hongcai Wang Tao Guo Yinsheng Ma Daogong Hu 1999Chinese Science Bulletin1999,44,15:1
