| 摘 要： | 本文对赛什腾－锡铁山斜冲断裂构造重点地段详细构造解析的基础上，结合沉积，地球物理资料该斜冲断裂构造的几何学，运动学及时代进行了研究，探讨了断裂形成与区域地质背景的关系，提出柴达木盆地北缘的塞什腾、绿梁山、锡铁山是向南斜向逆覆于新第三纪沉积岩之上的无根推覆体，并认为该断裂的形成与喜马拉雅造山带陆内俯冲远程效应相关。

| Abstract: | A Neogene left-lateral oblique turst fault-Sertengshan-Xitieshan oblique trust zone is recognized in the northern margin of Qaidam basin based on the analysis of structures of the area.This oblique trust fault zone with northwestern -southeastern trending consists of fault gouge,fault breccia and fault cleavage.Fault hanging wall is Sertengshan -Xitieshn napple,which is distribution in dextral en echelon.Fault footwall consists of Youcangshan Formation in Neogene.It is discussed that geological setting of the oblique thrust faults zone,is considered in connection with the long distance effection of Himalayan orogenic belt intracontinent subducting. |

| Keywords: | Qaidam basin Sertengshan-Xitieshan mountain Neogenne oblique thrust tectonics |
