塔里木盆地塔中北围斜区发育一系列北东走向的走滑断裂，主要发育花状构造、平行高陡断裂带、雁列构造等多种构造样式。加里东中期塔中Ⅰ号断裂、南缘断裂活动剧烈，北西向的逆掩岩片或滑动块体中由于差异运动而形成了北东走向的撕裂断层-调节断层。加里东末期塔中地区受到东南向强烈斜向挤压作用是走滑断裂形成的动力机制，在基底薄弱带的基础上，塔中地区发生了右旋走滑特征。在这种板内挤压转换构造背景下，形成了一些连接北西向逆冲断层的北东向走滑断裂。加里东晚期-海西早期断裂基本上沿着加里东中期的调节断层带的基础上继承发育，具有多期活动的特征。走滑断裂对碳酸盐岩储集层具有强烈的改造作用，还控制了古生界碎屑岩构造圈闭的发育，并作为重要的油气运移通道。

A series of strike-slip faults occurr in north peri-cline area of the Tazhong Uplift in the Tarim Basin .The struc-tural styles include flower structure , parallel high-steep fault , en-echelon structure etc .In the Middle Caledonian , the Tazhong-Ⅰfault and the southern boundary fault were most active ,and the NE-trending tear faults were formed because of the differential movement of NW-trending overthrust nappe or sliding block .In the Late Caledonian ,the Tazhong uplift experienced strong oblique compression from the SE direction , which was the dynamic mechanism for the formation of strike-slip faults .This resulted in right-lateral strike-slip on the basis of basement weak zone .NE-trending strike-slip faults were formed in the tectonic setting of intraplate transpressional nature ,and were connected with the NW-trending thrust fault .In the Late Caledonian to Early Hercynian ,faults were developed in inheritance along the Middle Caledonian tear faults,and were characterized by multistage activities .The strike-slip faults not only greatly modified carbonate reser-voirs,but also controlled the development of structural trap in the Paleozoic clasitc rocks .In addition,they also acted as important pathways of hydrocarbon migration .
