摘要： 塔里木盆地西部及邻区构造的形成机制,主要受控于印度板块的碰撞挤压作用,其次是西伯利亚和哈萨克斯坦板块的挤压作用：西南缘受控于帕米尔推覆体的推覆作用及东侧的扭动走滑作用的影响;南缘受西昆仑山的逆冲推覆作用的影响;北部和西北部,主要受柯坪弧形推覆构造隆起带的推覆作用的影响;东北部的巴楚断隆,受两个方向对冲的作用力,造成了特殊的扭动走滑体系。

Abstract: Structuring mechanism in western Tarim basin and its adjacent areas was primarily controlled by colision and extrusion of Indonian plate, and, to a less extent, by extrusion of Siberia and Kazakhstan plates: overthrust of Pamir nappe and shear strike slip to the east in southwest margin; overthrust of west Kunlun mountains in south mar-gin; overthrust of Kalpin arc overthrust uplift in northern and northwestern Tarim basin;and in the northeast, special shear strikes slip system arised from Bachu faulted uplift sub-jected to the collision in opposite directions.
