摘要： 台北凹陷是吐哈盆地的主体沉降区,受盆地北缘博格达山控制,自侏罗纪以来属于类前陆坳陷区，并在侏罗纪末以后形成了广泛的盖层挤压滑脱构造体系。凹陷中部的丘东、温吉桑构造与南部斜坡边缘的七克台逆冲带属于同一滑脱构造体系，处于滑脱构造体系后方的丘东、温吉桑构造则属于滑动褶皱,并且自侏罗纪末以来多期活动,与沉积作用结合，形成了特殊的地层结构和构造。由此可以进一步确定滑脱构造体系前部七克台逆冲带的形成活动期次和冲断规模,同时有助于客观分析滑脱构造体系的油气成藏特点。

Abstract: Taibei sag controlled by Mount Bogda is the major depressed area in Tuha basin. It has been in foreland sub-depression area since Jurassic, and formned decollement structural system with vast cap compression, including Qiudong and W enjisang structures in center of the sag and Qiketai thrust belt in the southern slope margin. The Qiudong and W enjisang structures behind the system belong to sliding folds, with special stratigraphic configuration after multi-stage movement since Late Jurassic. This paper determines the stages and thrusting scale of Qiketai thrust belt formation in front of the decollement structural system, which helps to impersonal analysis of the hydrocarbon accumulation within the system.

Key words: Tuha basin, Taibei sag, decollement structure, fold
