在前人研究的基础上，结合最新的野外发现，特别是放射虫硅质岩的发现，对东昆仑造山带南坡小区、阿尼玛卿山小区及巴颜喀拉山小区北部范围内的沉积地层序列进行了重建．根据沉积组合在地层纵向序列上的变化，将本区古海洋在海西—印支期的演化划分为４个阶段：浅特提斯海与阿尼玛卿洋的并存阶段、阿尼玛卿洋的闭合与巴颜喀拉海的诞生阶段、巴颜喀拉浊积盆地的形成阶段和陆内盆地磨拉石建造阶段
On the basis of the previous studies, combined with the latest field discoveries, especially the discovery of radiolarian cherts, it is very important for the discovery of the southern Kunlun orogenic belt south slope, Animaqing Hill community and the northern part of Bayan Harness district Sedimentary sequence was reconstructed. According to the variation of sedimentary assemblages in the longitudinal sequence of the strata, the evolution of the ancient ocean in the Hercynian-Indosinian period is divided into four stages: the coexistence phase of the shallow Tethys sea and the Animaqing ocean, The closure of the ocean and the birth of the Bayan Harhai Sea, the formation of the turbid basin in the Bayan Har and the construction of the molasse in the intracontinental basin
