新疆塔吐鲁沟地区大地构造位置属羌塘—三江造山系的塔什库尔干—甜水海陆块。塔什库尔干岩群构成了本区元古代结晶基底,主要为1套由区域变质作用形成的高绿片岩相-低角闪岩相变质岩系,其原岩和产出构造背景尚不明确。岩石学特征及岩石地球化学特征等研究表明,其原岩为1套正常沉积的碎屑岩夹基性-中酸性火山岩及碳酸盐岩建造,形成于板块拉张阶段的大陆裂谷、弧后盆地和稳定陆缘构造环境,分别反映了大陆裂解、洋壳形成及洋壳稳定伸展的大地构造背景,有助于进一步认识该区的地壳演化。
The tectonic position of the Tarulugou area in Xinjiang is the Taxkorgan-Tianshuihai block of the Qiangtang-Sanjiang orogenic belt. The Taxkorgan group constitutes the Proterozoic crystalline basement in this area, which is mainly composed of a series of high greenschist - low amphibolite metamorphic metamorphic rocks formed by regional metamorphism. The original rock and output tectonic setting are not yet clear. Petrology characteristics and geochemical characteristics of rock show that the original rock is a set of normal sedimentary clastic intercalated - acidic volcanic rocks and carbonate rocks, formed in the continental rift in the plateau tension stage, arc The post-basin and stable continental marginal tectonic setting respectively reflect the continental tectonic setting of the continental cleavage, oceanic crust formation and the stable extension of the oceanic crust, which helps to further understand the crustal evolution in this area.
