Abstract Subduction polarity reversal usually involves the break off or tearing of downgoing plate (DP) along continent-ocean transition zone, in order to initiate subduction overriding (OP) with opposite polarity. We propose that can also be caused by DP-OP coupling and account for early Paleozoic geological relationships Western Kunlun orogenic belt northwestern Tibetan Plateau. Our synthesis elemental isotopic data reveals transient (~2 m.y.) changes sources arc magmatism southern...
Abstract Cenozoic crustal thickening and surface uplift in Pamir, northwest Tibetan Plateau is controlled by India-Asia continental convergence post-collisional subduction processes. However, the nature evolution of subducted lithosphere associated deep dynamic processes remain unclear. In this study, we report new geochemistry, mineral chemistry geochronology for three plutons (Kuzigan, Karibasheng Zankan) eastern Central to constrain their petrogenesis help understand geodynamic LA-ICP-MS...
Oceanic arc subduction systems are the loci of substantial recycling oceanic crust and production juvenile that differentiates to more evolved felsic crust. Inevitably, some sediments subducted with However, distinguishing incorporation in arcs is not always straightforward, because they may measurably shift many geochemical signatures, such as Sr Nd isotopes, arcs. Nevertheless, combined zircon U-Pb, Hf, O isotope data can provide a powerful tool decipher sedimentary flux into magmas, here...
Abstract The petrogenesis of continental arc magmas provides critical insights into thermal evolution and geodynamics the lithosphere, crust-mantle interaction, deep dynamic processes. In this study, we report new zircon U-Pb ages along with isotopic elemental whole-rock geochemistry, mineral chemistry, Hf-O isotope data for Kalaqigu diorites monzogranites Chinese Wakhan Corridor, South Pamir. Zircon dating indicates that pluton was emplaced in Early Cretaceous (ca. 108–106 Ma). are...
Abstract Radiogenic isotopes serve as a crucial tool for investigating crustal evolution, playing pivotal role in revealing magma sources and petrogenesis. However, they can be ineffective distinguishing between distinct magmatic with similar radiogenic isotopic compositions, common occurrence nature. Here we addresse this challenge the Ordovician igneous rocks from West Kunlun orogenic belt (WKOB), aiming to distinguish two potential (i.e. Tarim Craton Tianshuihai terrane) compositions...
西昆仑造山带发育有大量的早古生代岩浆岩, 它们的形成与原特提斯洋俯冲-碰撞密切相关, 然而, 对于这些岩浆岩的岩石成因和形成的构造背景仍然存在较大的争议。本文对西昆仑造山带早古生代阿喀孜二长岩和赛图拉石英闪长岩岩体开展了详细的矿物学、锆石U-Pb年代学、全岩地球化学和Sr-Nd-Hf-O同位素研究, 以探讨这些侵入岩的岩浆源区与成因, 揭示原特提斯洋在这一时期的构造演化过程。这两个岩体的LA-ICP-MS锆石U-Pb年龄分别为456±2Ma和452±2Ma, 指示它们形成于晚奥陶世。阿喀孜二长岩具有富碱(K<sub>2</sub>O+Na<sub>2</sub>O=10.5%~11.8%)、富钾(K<sub>2</sub>O/Na<sub>2</sub>O=1.20~1.44)特征, 相对低MgO(0.89%~0.97%)、TiO<sub>2</sub>(0.42%~0.45 %)含量, 富集Rb、Th、U等大离子亲石元素, 且具有较高的全岩锆饱和温度(<i>T</i><sub>Zr</sub>=814~862℃),...
Peraluminous granitoids have aluminum saturation indices (A/CNK) higher than 1.0, which overlap to some extent between S- and I-type granitoids. However, their source petrogenesis are still disputed. For example, whole-rock compositions alone not always a valid way discriminate the sources of peraluminous To identify geochemical affinities, granitoids, we present new data, <i>in situ</i> zircon U-Pb ages Hf-O isotopic Sr-Nd data for in South Tianshan Orogen Belt (STOB), Northwesten China....
斑岩型矿床多形成于汇聚型板块边界。由于其较浅的就位深度，大部分古老的斑岩型矿床很容易受到后期的剥蚀而消失殆尽。研究斑岩型矿床成矿后的埋藏和去顶过程对于深入理解矿床的保存条件和区域找矿前景至关重要。新疆西准噶尔西部的苏云河斑岩型钼矿床形成于晚石炭世，是一处保存良好的斑岩型矿床，为我们研究前中生代斑岩成矿系统的保存条件提供了天然的实验室。本文首次针对该矿床开展了锆石和磷灰石裂变径迹与锆石（U-Th）/He低温热年代学分析，结合热历史反演模拟以及前人的年代学数据显示，苏云河斑岩钼矿的蚀变过程至少持续了55Myr。在早二叠世到中三叠世，矿区接受5.2~8.1km厚的沉积物覆盖。中三叠世至早白垩世（240~120Ma），矿床经历了快速剥露作用，剥露速率为49.0~56.7m/Myr，去顶量为7.4~9.2km。早白垩世（120Ma）至今为缓慢剥露阶段，剥露速率为6.7~21.7m/Myr，去顶量为0.8~2.6km。中三叠世至早白垩世的快速冷却事件可能并不是特定构造事件（比如：南部羌塘和昆仑-柴达木碰撞或者羌塘和拉萨碰撞）远程效应的产物，而与区域内走滑断层的活化密切相关。而矿床早期沉积的巨...

The petrogenesis and geodynamic setting of the Mesozoic magmatic rocks in Erguna Block, NE China remains controversial, especially relationship between magmatism subduction history Mongol–Okhotsk oceanic plate. Here we present data for Early Jurassic–Early Cretaceous adakite-like from Chaoman Farm northeastern part Block.
