本项目瞄准大陆复合造山带中不同造山阶段构造演化与造山过程问题，以东昆仑造山带东段晚古生代-早中生代阶段沉积地层中发育的4个区域性不整合面及其构造变形差异为标志并划分构造演化阶段，将沉积盆地形成演化与构造岩浆作用有机联系起来，通过对东昆仑东段晚古生代-早中生代沉积地层的沉积岩石组合、盆地充填序列、沉积盆地性质、物质来源、盆山转换、变形特征进行详细研究，对晚古生代晚期-中生代不同构造演化阶段形成的花岗岩类的岩石组合、构造属性、形成时代和形成构造环境进行详细研究，在详细研究和划分其物质组成和形成时代、复合造山作用基础上，恢复重建晚古生代-早中生代以南侧阿尼玛卿-布青山古特提斯洋盆为主要动力学背景的东昆仑东段晚古生代-早中生代区域构造格局及其构造演化过程，对于探索古特提斯构造域北洋盆的形成演化及与东昆仑造山带的复合叠置构造过程以及大陆复合造山带形成演化与机制等大陆动力学问题均具有重要科学意义。

This project mainly aimes at the orogenic process and tectonic evolution of different orogenic stage in continental composite orogenic belt, and divide tectonic evolution stage based on the four regional unconformity surface and tectonic deformation difference in late Paleozoic-early Mesozoic sedimentary strata. This project study the sedimentary rock assemblage, basin filling sequences, sedimentary basin properties, material sources, basin-mountain transformation and deformation characteristics of the late Paleozoic-early Mesozoic sedimentary strata. On the other hand, rock association, tectonic properties, formation age and tectonic setting of granitoid rocks formed in different tectonic stage are also studied detailedly. On the basis of the detailed research and classification of material composition, formation age and compound orogeny, we would reconstruct the late Paleozoic-early Mesozoic regional tectonic framework and tectonic evolution process under the geodynamic background mainly dominated by Buqingshan-A'nyemagen Paleotethys Ocean, which have important scientific significance to explore the evolution of the northern ocean basin concerning Paleotethys domain, composite tectonic overlap process, evolution mechanism of continental composite orogenic belt and other continental dynamics problems.
