Petrogenesis of Triassic Hongshuihe Granitoids in East Kunlun: Implications for the Paleo-Tethyan Orogeny

摘要: 东昆仑三叠纪岩浆岩的是研究古特提斯造山作用过程的重要探针. 对东昆仑洪水河地区花岗岩类开展了详细的岩石学、年代学、地球化学和Sr-Nd同位素研究，探讨其成因机制及动力学背景. 锆石U-Pb年代学研究表明，洪水河花岗闪长岩和花岗岩的结晶年龄分别为243.0 Ma±3.3 Ma和244.0 Ma±3.1 Ma. 两类岩石均属于准铝质高钾钙碱性Ⅰ型花岗岩，但花岗闪长岩具有较低的Na2O/K2O比值（0.78~0.96）和较高的Mg#（42~45）. 岩石均富集大离子亲石元素，亏损高场强元素，且具有富集的Sr-Nd同位素组成[εNd（t=243）=-6.53~-4.99，Isr=0.706 871~0.709 126]. 综合分析表明，洪水河地区三叠纪花岗岩类形成于古特提斯洋壳俯冲的陆缘弧环境，岩浆起源于中元代变质杂砂岩的部分熔融，且经历了不同程度的壳幔混合作用和分离结晶作用.研究揭示，古老大陆地壳的重熔与一定量的壳幔混合作用是东昆仑中三叠世大陆地壳的主要演化方式.Abstract: Triassic magmatic rocks in East Kunlun are the key probe to study the Paleo-Tethyan orogeny. This paper presents a detailed petrological, chronological, geochemical and Sr-Nd isotopic study on the Hongshuihe granitoids in the East Kunlun to constrain their petrogenesis and dynamic setting. Zircon U-Pb chronology shows that the crystallization ages of the granodiorite and granites in the Hongshuihe pluton are 243.0 Ma±3.3 Ma and 244.0 Ma±3.1 Ma, respectively. The studied rocks are metaluminous, high-K calc-alkaline Ⅰ-type granitoids, but the granodiorites have lower Na2O/K2O ratios (0.78-0.96) and higher Mg# (42-45) than the granites. All rocks are enriched in large ion lithophile elements but depleted in high field strength elements, and have an enriched Sr-Nd isotopic composition [εNd(t)=-6.53~-4.99, Isr=0.706 871~0.709 126]. Comprehensive studies indicate that the Hongshuihe middle Triassic granitoids were formed in the continental arc environment during the East Kunlun Paleo-Tethyan oceanic crust subduction, and their parental magmas were derived by partial melting of Mesoproterozoic metagreywackes followed by varying degrees of crust-mantle mixing and fractional crystallization. This study also shows that the re-working of ancient continental crust with a certain amount of crust-mantle mixing is the main evolutionary mechanism of Middle Triassic continental crust in the East Kunlun.
