摘　　要：研究区位于塔里木盆地的西部 ,以吐木休克断裂带为界将研究区划分为巴楚断隆和阿瓦提凹陷两个构造单元。在对吐木休克断裂带的几何学、运动学特征研究的基础上 ,指出该断裂带是沿着断层传播褶皱或断层转折褶皱轴面形成的右行逆冲走滑断裂带 ,对早期构造主要起破坏作用 ,它控制了巴楚断隆和阿瓦提凹陷的形成和发展。吐木休克断裂带的出现与印藏碰撞的远距离效应有关 ,其形成开始于老第三纪 。The research area is situated in the western part of Tarim basin. It can be divided into Bachu block uplift and Awati depression by Tumuxiuke fault belt. The study of geometry, kinematics and geodynamics of Tumuxiuke fault belt show that the Tumuxiuke fault belt is a dextral reversed strike-slip fault which formed along the axial surfaces of the fault band fold or fault propagation fold. It destructed the early structures and controlled the formation and development of Bachu block uplift and Awati depression. Tumuxiuke fault belt was formed from Tertiary, and caused by the remote effect of India-Tibet collision. Up to now it has been activity.
