Abstract:The most striking tectonic feature of the northem part of the Tarim basin is that it is cut by the ENE—trending regional faults,forming a tectonic franework of north—south zoning and east- west regionalization.Based on the analysis of geometry and kinematics,the author think that the main fauks striking NW in Northem Tarim Basin are Characterized by deformation of based— mentinvolved Compressional thrust,Which were controled by plate tectonics evolution of nouth- westem margin of Tarim plate during Mezo—Cenozoic time period。The most important events happened in this period were collision between western kunlun terrane and Tarim plate in the ending of early Permian,collision between Kalakunlun terrane and western Kunlun in Jurasic, and collision of Indian plate and south Asian continental margin in Tertiar
