Abstract Water is essential for the formation of granites and continental crust, whereas charnockite, being an important component deep inferred to be formed in low‐water environments. Charnockite orthopyroxene‐bearing felsic rock, its origin, generation, preservation remain hotly debated. Quantifying magma water content charnockite further determining orthopyroxene mechanism crucial understanding petrogenesis charnockite. Here, we report a ca. 431 Ma peraluminous Gaozhou with granulitic...
A better understanding of Neoproterozoic glacial events and continental chemical weathering signals during syn-, inter-, post-glaciation is crucial to the study global glaciation. Middle−late strata have been identified at southwestern margin Tarim Craton in China, but their sedimentary environment, evolutionary history intensity, how relate remain unclear. This presents new sedimentological, geochronological, geochemical data address these concerns. The sedimentology indicates an...
Abstract We carried out a paleomagnetic investigation on Permian volcanic rocks from central eastern Inner Mongolia, NE China, in order to identify the paleoposition of North China and Songliao‐Xilinhot blocks during Permo‐Carboniferous times thereby define spatial‐temporal history Paleo‐Asian Ocean (PAO). Two prefolding magnetization components were isolated Sanmianjing Elitu Formations (~283–266 Ma) along northern margin block (NMNCB) Dashizhai Formation (~280 (SXB). These two results...
Abstract Dating the closure of Paleo‐Asian Ocean (PAO) is critical to our understanding East Asian tectonics during formation Pangea, yet existing estimates differ by up 130 Myr (380–250 Ma). We report two robust paleomagnetic results from 320 280 Ma volcanic strata in South Mongolia‐Xing’an Belt. Stable characteristic remanences both are likely primary and characterized positive fold tests, consistent polarity with Kiaman Superchron (∼318–262 Ma) average paleosecular variation. The new...
Abstract Constraining the positions of, and interrelationships between, Earth's major continental blocks has played a role in validating concept of supercontinent cycle. Minor fragments can provide additional key constraints on modes assembly dispersal. The Tarim craton been placed both at core Rodinia or its periphery, differentiating between two scenarios widespread implications for breakup subsequent Gondwana. In South terrane, detrital zircon grains from Neoproterozoic–Silurian strata...
Abstract The drift of Gondwana‐derived blocks across the Tethys has remained unclear specifically because one largest components, Indochina, unconstrained by paleomagnetism during late Paleozoic, interval comprising first half its journey towards Eurasian landmass. Hence, we report a paleomagnetic study Early‐Middle Permian limestones from central Thailand yielding high‐quality data set for Indochina Block with probable primary origin. magnetization yields pole at 34.1°N, 331.7°E ( K = 45.4,...
Abstract Amuria formed in the late Paleozoic through amalgamation of Mongolia and Songliao‐Jiamusi blocks eastern Central Asian Orogenic Belt (CAOB). The exact timing assembly is critical towards unraveling Phanerozoic evolution Paleo‐Asian Ocean (PAO) Pangea. Here, we report first Permo‐Carboniferous paleomagnetic data from block, aiming to constrain its relative paleoposition with respect Mongolia. A stable characteristic remanent magnetization (ChRM) was isolated 313–292 Ma...
也认为晚古生代华北板块与中亚诸板块之间 为陆壳基底之上发育的陆表海和裂陷槽而非宽阔的大 洋洋盆.而Xiao等人 [3] 则识别出6套代表活动陆缘和增 生楔的构造单元, 认为温都尔庙增生杂岩、白乃庙岛 弧以及贺根山、宝力道增生杂岩分别代表了古亚洲洋 早古生代和晚古生代的俯冲记录, 直至晚二叠世才完 成最终闭合.以前的古地磁研究认为晚二叠世华北-蒙古联合块 体已经形成, 其与西伯利亚的拼合则是晚侏罗世至早白 垩世沿蒙古-鄂霍茨克缝合带闭合 [9~13] .而对于晚二叠世 之前东古亚洲洋的演化, 古地磁研究提供的限定仍很缺 乏.Zhao等人 [14] 在内蒙古板块(相当于本文松辽-锡林浩 特地块, 图1(a))获得了一个晚泥盆世的古地磁极, 认为 此时已经与华北、蒙古无古纬度差异
Abstract Final closure of the Palaeo‐Asian Ocean signifies ultimate amalgamation North China, Tarim, Mongolia, Songliao, Xilinhot and other Central Asian blocks, therefore, is critical in reconstructing configuration Pangea supercontinent during late Palaeozoic to early Mesozoic. However, final time remains contentious. Here, we present a systematic palaeomagnetic study on Upper Permian sedimentary sequences Block, located north Solonker Suture Zone. Rock magnetic results indicate stable...
SUMMARY Palaeomagnetic constraints are essential factors in the reconstruction of Mesozoic convergence Eastern Asia blocks. As one key blocks, Indochina was constrained only by sedimentary-rocks-derived palaeomagnetic data. To evaluate whether data used to restore Late Triassic position suffered inclination shallowing effects, we conducted a and geochronologic study on coeval volcanic clastic rocks sequence western margin Khorat Basin, Thailand. The U-Pb SIMS dating zircons indicates age...
印支地块是东亚大陆主要陆块之一，其主体位于东南亚地区。过去的研究认为其可能来源于古生代的冈瓦纳大陆，伴随着晚古生代以来的特提斯洋演化过程，印支地块逐渐从南半球冈瓦纳大陆裂离，向北半球漂移并汇聚拼贴到东亚大陆上来。随着近几年的古地磁学工作的进展，获得了丰富的定量半定量数据，印支地块晚古生代以来的运动过程才得到了较为精确的重建。本文通过详细总结和深入分析前人发表的和我们最新从印支地块获得的古地磁数据，系统地刻画了晚古生代以来印支地块从南半球向北半球的漂移运动过程。晚古生代印支地块位于南半球中低纬度地区，在二叠纪末期跨越赤道，到了晚三叠世运动到北半球30°N附近，很可能此时已经拼贴到欧亚大陆主体上来，中生代之后又经历了一系列的构造调整。基于古地磁数据的运动学重建，使得古特提斯构造域主要块体的构造关系和相对运动历史也得到了进一步的厘定，从运动学的角度证明了北羌塘地块和印支地块具有明确的古地理亲缘关系，同时，两者与滇缅泰地块和南羌塘地块的运动过程具有明显的区别。结合东亚诸关键陆块的最新古地磁学研究进展，细致重建了东亚陆块群对Pangea超大陆汇聚过程的独特响应。
