【摘要】 塔里木盆地北部(简称塔北)区域构造上最显著的特征是受走向ENE和NW两组区域性大断裂的控制,形成了南北分带、东西分块的基本构造格局。本区NW向断裂以基底卷入型压性逆冲为基本特点。构造发育受中新生代塔里木板块西南缘大地构造演化控制。这一时期的主要地质事件有早二叠纪末期塔里木板块与西昆仑地体的碰撞;侏罗纪西昆仑地体与喀喇昆仑地体的碰撞;第三纪印度板块与欧亚板块的碰撞。更多还原

【Abstract】 The most striking tectonic feature of the northern 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 eastwest regionalization.Based on the analysis of geometry and kinematics,the author think that the main faults striking NW in Northern Tarim Basin are Characterized by deformation of basedmentinvolved Compressional thrust,Which were controled by plate tectonics evolution of nouthwestem 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 Tertiary.更多还原
