摘要

英吉苏凹陷与库车坳陷同处于塔里木盆地北缘,三叠纪以来二者具有类似的沉积―构造演化历史。根据英吉苏凹陷目前的勘探程度和中生界的构造格架,把英吉苏凹陷整体划分为\"二洼一凸\"的构造格局,即英西洼槽、维马克―阿拉干低凸起、英东洼槽,进一步细分为5个三级构造带。认为区内断层以逆冲断层为主,主要表现为北西向和北东向两组,构造演化表现为受阿尔金走滑构造活动影响形成的侏罗系陆内走滑-压陷盆地,剖面上其呈宽缓的\"牛头\"状。

Abstract

Yingjisu depression lies in north of the Tarim basin as same as Kuche depression,they have the same deposit-tectonic evolution history. Yingjisu depression is separateda Two hollows and one protruding\" according to exploration and Mesozoic tectonic-structure, they are Yingxi hollow, Weimake-alagan low protruding and Yingdong hollow,it is separated five triple-tectonic parts particularly. Many northwestern and northeastern reverse-fauts lie in the region.It is a slide-extruding basin for the Aljin mountain.
