塔里木盆地及周缘发育八种断裂构造样式。属于盖层滑脱型样式有叠瓦逆冲构造、被动顶板反冲,双重道冲构造和对冲构造。属于基底卷入型样式有背冲构造、冲断构造、走滑构造、同向旋转断块构造和地堑构造(平直正断层).其中背冲、叠瓦道冲和双重逆冲构造与油气关系最为密切。
There are 8 fault structural styles in Tarim Basin and its periphery.Some of them are ofthe caprock detachment origin which include imbricate thrust, passive roof recoiled thrustand ramp structures developed mostly in Kuche marginal foreland basin and the back-arcforeland basin of Southwest Tarim Basin,and are related to detachment sequences andsedimentary-structural loading in the above mentioned two basins.Others belong to basement involved type that include back thrust,thrust,strike-slip,homodromous fault blockand graben structures developed mainly in the internal palaeo-uplifts in Tarim Basin or onthe transform margins in geological history.Among the styles,the back-thrust,imbricatethrust and duplex thrust structrues are more important to hydrocarbon exploration.
