| 3 | Late 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 | 2009 | Acta Geologica Sinica(English Edition)2009，83，2： | 17 |
| 4 | Memory materials and devices:From concept to application显示文摘Memory cells have always been an important element of information technology.With emerging technologies like big data and cloud computing,the scale and complexity of data storage has reached an unprecedented peak with a much higher requirement for memory technology.As is well known,better data storage is mostly achieved by miniaturization.However,as the size of the memory device is reduced,a series of problems,such as drain gate-induced leakage,greatly hinder the performance of memory units.To meet the increasing demands of information technology,novel and high-performance memory is urgently needed.Fortunately,emerging memory technologies are expected to improve memory performance and drive the information revolution.This review will focus on the progress of several emerging memory technologies,including two-dimensional material-based memories,resistance random access memory(RRAM),magnetic random access memory(MRAM),and phasechange random access memory(PCRAM).Advantages,mechanisms,and applications of these diverse memory technologies will be discussed in this review. | Zhenhan Zhang Zongwei Wang Tuo Shi Chong Bi Feng Rao Yimao Cai Qi Liu Huaqiang Wu Peng Zhou | 2020 | InfoMat2020，2，2： | 15 |
| 5 | Early 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 | 2013 | Acta Geologica Sinica(English Edition)2013，87，2： | 9 |
| 6 | Middle-Late Pleistocene Glacial Lakes in the Grand Canyon of the Tsangpo River,Tibet显示文摘Many moraines formed between Daduka and Chibai in the Tsangpo River valley since Middle Pleistocene.A prominent set of lacustrine and alluvial terraces on the valley margin along both the Tsangpo and Nyang Rivers formed during Quaternary glacial epoch demonstrate lakes were created by damming of the river.Research was conducted on the geological environment,contained sediments,spatial distribution,timing,and formation and destruction of these paleolakes.The lacustrine sediments 14C(10537±268 aBP at Linzhi Brick and Tile Factory,22510±580 aBP and 13925±204 aBP at Bengga,21096±1466 aBP at Yusong) and a series of ESR(electron spin resonance) ages at Linzhi town and previous data by other experts,paleolakes persisted for 691~505 kaBP middle Pleistocene ice age,75-40 kaBP the early stage of last glacier,27-8 kaBP Last Glacier Maximum(LGM),existence time of lakes gradually shorten represents glacial scale and dam moraine supply potential gradually cut down,paleolakes and dam scale also gradually diminished.This article calculated the average lacustrine sedimentary rate of Gega paleolake in LGM was 12.5 mm/a,demonstrates Mount Namjagbarwa uplifted strongly at the same time,the sedimentary rate of Gega paleolake is more larger than that of enclosed lakes of plateau inland shows the climatic variation of Mount Namjagbarwa is more larger and plateau margin uplifted more quicker than plateau inland.This article analyzed formation and decay cause about the Zelunglung glacier on the west flank of Mount Namjagbarwa got into the Tsangpo River valley and blocked it for tectonic and climatic factors.There is a site of blocking the valley from Gega to Chibai.This article according to moraines and lacustrine sediments yielded paleolakes scale:the lowest lake base altitude 2850 m,the highest lake surface altitude 3585 m,3240 m and 3180 m,area 2885 km2,820 km2 and 810 km2,lake maximum depth of 735 m,390 m and 330 m.We disclose the reason that previous experts discovered there were different age moraines dividing line of altitude 3180 m at the entrance of the Tsangpo Grand Canyon is dammed lake erosive decay under altitude 3180 m moraines in the last glacier era covering moraines in the early ice age of late Pleistocene,top 3180 m in the last glacier moraine remained because ancient dammed lakes didn't erode it under 3180 m moraines in the early ice age of late Pleistocene exposed.The reason of the top elevation 3585 m moraines in the middle Pleistocene ice age likes that of altitude 3180 m.There were three times dammed lakes by glacier blocking the Tsangpo River during Quaternary glacial period.During other glacial and interglacial period the Zelunglung glacier often extended the valley but moraine supplemental speed of the dam was smaller than that of fluvial erosion and moraine movement,dam quickly disappeared and didn't form stable lake. | ZHU Song WU Zhenhan ZHAO Xitao LI Jianping WANG Hua | 2012 | Acta Geologica Sinica(English Edition)2012，86，1： | 8 |

| 8 | Dextral-Slip Thrust Faulting and Seismic Events of the Ms 8.0 Wenchuan Earthquake,Longmenshan Mountains,Eastern Margin of the Tibetan Plateau显示文摘Dextral-slip thrust movement of the Songpan-Garzê terrain over the Sichuan block caused the M_s 8.0 Wenchuan earthquake of May 12,2008 and offset the Central Longmenshan Fault(CLF) along a distance of~250 km.Displacement along the CLF changes from Yingxiu to Qingchuan.The total oblique slip of up to 7.6 m in Yingxiu near the epicenter of the earthquake,decreases northeastward to 5.3 m,6.6 m,4.4 m,2.5 m and 1.1 m in Hongkou,Beichuan,Pingtong,Nanba and Qingchuan,respectively.This offset apparently occurred during a sequence of four reported seismic events,EQ1-EQ4,which were identified by seismic inversion of the source mechanism.These events occurred in rapid succession as the fault break propagated northeastward during the earthquake. Variations in the plunge of slickensides along the CLF appear to match these events.The Mw 7.5 EQ1 event occurred during the first 0-10 s along the Yingxiu-Hongkou section of the CLF and is characterized by 1.7 m vertical slip and vertical slickensides.The Mw 8.0 EQ2 event,which occurred during the next 10-42 s along the Yingxiu-Yanziyan section of the CLF,is marked by major dextralslip with minor thrust and slickensides plunging 25°-35°southwestward.The Mw 7.5 EQ3 event occurred during the following 42-60 s and resulted in dextral-slip and slickensides plunging 10°southwestward in Beichuan and plunging 73°southwestward in Hongkou.The Mw 7.7 EQ4 event, which occurred during the final 60-95 s along the Beichuan-Qingchuan section of the CLF,is characterized by nearly equal values of dextral and vertical slips with slickensides plunging 45°-50°southwestward.These seismic events match and evidently controlled the concentrations of landslide dams caused by the Wenchuan earthquake in Longmenshan Mountains. | WU Zhenhan DONG Shuwen Patrick J.

| 9 | Fission Track Thermochronology Evidence for the Cretaceous and Paleogene Tectonic Event of Nyainrong Microcontinent, Tibet显示文摘Fission track dating was applied to analyze the 20 samples from Nyainrong microcontinent, and we obtained 20 apatite and 15 zircon fission track ages. The results show single population grain ages with a single mean age and associated central ages mainly ranging from 108±7Ma to 35±4Ma.Their mean track lengths are 12.2–13.9 μm with a single peak. Zircon fission track age range from 78±3 Ma to 117±4 Ma. The results represented the two tectonic uplift events in the study area, namely the Cretaceous and Paleogene periods. According to thermal history modeling results, uplifting rates of two tectonic events is 0.31–0.1 mm/a and 0.07–0.04 mm/a respectively. Combined with field condition and study results, it is suggested that the Cretaceous tectonic uplift event was related to the closure ocean basin caused by Qaingtang–Lhasa collision, and the Paleogene tectonic uplift event was related to the south to thrust system caused by Indo–Asian collision. | LU Lu ZHAO Zhen WU Zhenhan QIAN Cheng YE Peisheng | 2015 | Acta Geologica Sinica(English Edition)2015，89，1： | 8 |
| 10 | Early Cretaceous Tectonics and Evolution of the Tibetan Plateau显示文摘Selected geological data on Early Cretaceous strata, structures, magmatic plutons and volcanic rocks from the Kunlun to Himalaya Mountains reveal a new view of the Early Cretaceous paleo-tectonics and the related geodynamic movement of the Tibetan Plateau. Two major paleooceans, the Mid-Tethys Ocean between the Qiangtang and Lhasa blocks, and the Neo-Tethys Ocean between the Lhasa and Himalayan blocks, existed in the Tibetan region in the Early Cretaceous. The Himalayan Marginal and South Lhasa Seas formed in the southern and northern margins of the NeoTethys Ocean, the Central Tibet Sea and the Qiangtang Marginal Sea formed in the southern and northern margins of the Mid-Tethys Ocean, respectively. An arm of the sea extended into the southwestern Tarim basin in the Early Cretaceous. Early Cretaceous intensive thrusting, magmatic emplacement and volcanic eruptions occurred in the central and northern Lhasa Block, while strikeslip formed along the Hoh-Xil and South Kunlun Faults in the northern Tibetan region. Early Cretaceous tectonics together with magmatic K2O geochemistry indicate an Early Cretaceous southward subduction of the Mid-Tethys Oceanic Plate along the Bangoin-Nujiang Suture which was thrust 87 km southward during the Late Cretaceous-Early Cenozoic. No intensive thrust and magmatic emplacement occurred in the Early Cretaceous in the Himalayan and southern Lhasa Blocks, indicating that the spreading Neo-Tethys Oceanic Plate had not been subducted in the Early Cretaceous. To the north, terrestrial basins of red-beds formed in the Hoh-Xil, Kunlun, Qilian and the northeastern Tarim blocks in Early Cretaceous, and the Qiangtang Marginal Sea disappeared after the Qiangtang Block uplifted in the late Early Cretaceous. | WU Zhenhan ZHAO Zhen Patrick J.

| 11 | ESR Dating of the Evolution of the Shuanghu Basin in the Northern Tibetan Plateau显示文摘The Shuanghu basin is a NE-trending rift basin bounded by NE-striking normal faults and NW-striking shear-extensional faults of the northern Tibetan Plateau. Four samples from calcite veins in marginal faults and one sample from mudstone (S-3) were collected for dating the evolution of the Shuanghu basin by using the ESR spectrograph of EXM-type. Ages were calculated according to the close-equilibrium model on the basis of the measured ESR signal spectra of samples, providing good chronological information. It is known from the ESR dating that the extensional faulting and rifting of the Shuanghu area began at 4.92 Ma B.P., followed by regional folding in 3.56-1.36 Ma, NW-striking faulting in 0.60 Ma and normal faulting in 0.024 Ma in the Shuanghu basin. | WU Zhenhan JIANG Wan Peter Blisniuk BI Siwen ZHANG Shukun Olaf Kuchel MAO Yi | 1999 | Acta Geologica Sinica(English Edition)1999，73，3： | 6 |

| 13 | Zircon 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 | 2014 | Journal of Earth Science2014，25，3： | 3 |
| 14 | The Late Triassic I-Type Granites from the Longmu Co-Shuanghu Suture Zone in the interior of Tibetan Plateau, China: Petrogenesis and Implication for Slab Break-Off显示文摘The Jiangaidarina granitic mass(JM) is an important part of the magmatic belt in Longmu CoShuanghu Suture Zone(LSSZ) in the central Tibetan Plateau. An integrated research involving wholerock geochemistry, zircon LA-ICP-MS U-Pb ages and Hf isotopic compositions was carried out to define the timing, genesis and tectonic setting of the JM. Zircon LA-ICP-MS U-Pb ages have been obtained ranging from 210 to 215 Ma, rather than the Early Jurassic as previously thought. Fifteen granite samples contain hornblendes and show a negative correlation between P_2 O_5 and SiO_2, indicating that the JM is an I-type granite. All the granites are enriched in LREE relative to HREE, with negative Eu anomalies(Eu/Eu*=0.56-0.81), and have similar trace elements patterns, with depletion of Ba, Nb, Sr and P. These suggest that the JM was fractionated, and this is also proved by the characteristic of negative correlations between oxide elements(TiO_2, MgO, FeOt, MnO, CaO) and SiO_2. Almost all ε_(Hf)(t) values of the granites are between-10.3 and-5.8, implying that the JM has a crustal source intimately related with the South Qiangtang Block(SQB), except for one(+10.2), showing a minor contribution from mantle source.Moreover, relatively low Na_2 O/K_2 O ratios(0.42-0.93) and high A/CNK values(0.91-1.50) reflect that the JM was predominately derived from the medium-high potassium basaltic crust, interacted with greywacke. Our new geochemical data and geochronological results imply that the Late Triassic magmas were generated in a post-collisional tectonic setting, probably caused by slab break-off of the Longmu Co-Shuanghu Tethyan Ocean(LSTO). This mechanism caused the asthenosphere upwelling, formed extension setting, offered an enormous amount of heat, and provided favorable conditions for emplacement of voluminous felsic magmas. Furthermore, the LSTO could be completely closed during the Middle Triassic, succeed by continental collision and later the slab broke off in the Late Triassic. | ZHAO Zhen WU Zhenhan LU Lu YU Junqiu WU Yanjun | 2018 | Acta Geologica Sinica(English Edition)2018，92，3： | 2 |
| 15 | Tectonics and Topography of the Tibetan Plateau in Early Miocene显示文摘Early Miocene stratigraphy, major structural systems, magmatic emplacement, volcanic eruption, vegetation change and paleo-elevation were analyzed for the Tibetan Plateau after regional geological mapping at a scale of 1:250,000 and related researches, revealing much more information for tectonic evolution and topographic change of the high plateau caused by Indian-Asian continental collision. Lacustrine deposits of dolostone, dolomite limestone, limestone, marl, sandstone and conglomerate of weak deformation formed extensively in the central Tibetan Plateau, indicating that vast lake complexes as large as 100,000–120,000 km2 existed in the central plateau during Early Miocene. Sporopollen assemblages contained in the lacustrine strata indicate the disappearance of most tropical-subtropical broad-leaved trees since Early Miocene and the flourishing of dark needleleaved trees during Early Miocene. Such vegetation changes adjusted for latitude and global climate variations demonstrate that the central Tibetan Plateau rose to ca. 4,000–4,500 m and the northeastern plateau uplifted to ca. 3,500–4,000 m before the Early Miocene. Intensive thrust and crustal thickening occurred in the areas surrounding central Tibetan Plateau in Early Miocene, formed Gangdise Thrust System(GTS) in the southern Lhasa block, Zedong-Renbu Thrust(ZRT) in the northern Himalaya block, Main Central Thrust(MCT) and Main Boundary Thrust(MBT) in the southern Himalaya block, and regional thrust systems in the Qaidam, Qilian, West Kunlun and Songpan-Ganzi blocks. Foreland basins formed in Early Miocene along major thrust systems, e.g. the Siwalik basin along MCT, Yalung-Zangbu Basin along GTS and ZRT, southwestern Tarim depression along West Kunlun Thrust, and large foreland basins along major thrust systems in the northeastern margin of the plateau. Intensive volcanic eruptions formed in the Qiangtang, Hoh-Xil and Kunlun blocks, porphyry granites and volcanic eruptions formed in the Nainqentanglha and Gangdise Mts., and leucogranites and granites formed in the Himalaya and Longmenshan Mts. in Early Miocene. The K2O weight percentages of Early Miocene magmatic rocks in the Gangdise and Himlayan Mts. are found to increase with distance from the MBT, indicating the genetic relationship between regional magmatism and subduction of Indian continental plate in Early Miocene. | WU Zhenhan YANG Yan Patrick J.

| 16 | Thermal Evolution of Plutons and Uplift Process of the Yanshan Orogenic Belt显示文摘Thermochronological dating was used to study the thermal evolution of the Mesozoic plutons and uplift history of the Yanshan orogenic belt. The results show that the cooling history of the plutons is complicated, corresponding to the inhomogeneous uplift process of the Yanshan orogenic belt. The Panshan granite cooled fast during 226.48-204.95 Ma at a rate of 10.22℃/Ma after its emplacement at a depth of about 10 km, and its fast uplift occurred in about 96-35 Ma at an average rate of 0.115 mm/a. The Wulingshan pluton cooled fast during 132-127.23 Ma at a rate of 94.34℃/Ma, and its rapid uplift occurred in 86-45 Ma at an average rate of 0.186 mm/a. The Yunmengshan granite cooled fast during 143-120.99 Ma at a rate of 19.51℃/Ma, and its rapid uplift occurred in 106-103.95 Ma and 20-0.0 Ma at a rate of 1.06 mm/a and 0.15 mm/a respectively. The Sihetang granite-gneiss uplifted rapidly since 13 Ma at an average rate of 0.256 mm/a. The Badaling granite uplifted rapidly since 6 Ma at an average rate of 0. | WU Zhenhan CUI Shengqin ZHU Dagang FENG Xiangyang MA Yinsheng | 2000 | Acta Geologica Sinica(English Edition)2000，74，1： | 2 |
| 17 | Ordovician Granitoids and Silurian Mafic Dikes in the Western Kunlun Orogen, Northwest China:Implications for Evolution of the Proto-Tethys显示文摘The western Kunlun orogen in the northwest Tibet Plateau is related to subduction and collision of Proto-and Paleo-Tethys from early Paleozoic to early Mesozoic. This paper presents new LA-ICPMS zircon U-Pb ages and Lu-Hf isotopes, whole-rock major and trace elements, and Sr–Nd isotopes of two Ordovician granitoid plutons(466–455 Ma) and their Silurian mafic dikes(~436 Ma) in the western Kunlun orogen. These granitoids show peraluminous high-K calcalkaline characteristics, with(^(87)Sr/^(86)Sr)_i value of 0.7129–0.7224, ε_(Nd)(t) values of -9.3 to -7.0 and zircon ε_(Hf)(t) values of -17.3 to -0.2, indicating that they were formed by partial melting of ancient lower-crust(metaigneous rocks mixed with metasedimentary rocks) with some mantle materials in response to subduction of the Proto-Tethyan Ocean and following collision. The Silurian mafic dikes were considered to have been derived from a low degree of partial melting of primary mafic magma. These mafic dikes show initial ^(87)Sr/^(86)Sr ratios of 0.7101–0.7152 and ε_(Nd)(t) values of -3.8 to -3.4 and zircon ε_(Hf)(t) values of -8.8 to -4.9, indicating that they were derived from enriched mantle in response to post-collisional slab break-off. Combined with regional geology, our new data provide valuable insight into late evolution of the Proto-Tethys. | ZHANG Qichao WU Zhenhan LI Shan LI Kan LIU Zhiwei ZHOU Qing | 2019 | Acta Geologica Sinica(English Edition)2019，93，1： | 2 |
