摘要
塔里木盆地西南和相邻帕米尔一西昆仑地区构造关系十分密切，特提斯末期构造演化在特提斯东段形成独特的构造现象：突利状弧形构造（构造结）。帕米尔构造结的演化过程控制了这一区域构造格局，构造转换在该时段是主要构造作用形式之一，已知形成著名的恰曼左行走滑断裂系、塔什库尔干右行走滑盆地、康西瓦右行走滑构造带等。同时作者还在七美干一带发现帕米尔－西昆仑前缘构造转换域的存在，使得前陆冲断带和前陆沉降带横向不能连接．因而山前的构造变形呈现分阶段发育的特征。这对于帕米尔高原医升过程中地壳缩短机制和西昆仑山前缘新元古宙一下古生界的研究，具有重要的意义。
Southwest region of Tarim basin and the neigboring Parmir and west Kumlum region has a close relationship in tectonic evolution. The teclonic evolution of the end stage of Tethys formed a unique tectonic setting in the east part of Tethys domain: a delta shaped arc tectonics (tectonic tie).The regional tectonic framwork is controlled by the evolution of Parmir tectonic tie, tectonic transform is one of the most common tectonic type. the Qiaman left-lateral strike slip fault as well as the Taxkurgon and Kangxiwa right-lateral strike slip faults were identified in this region. The author also examined a frontal tectionic transform domain of Parmir-west kunlun in Qimeigan region, which made it discontinous between the frontal overthrusting belt and the subsiding belt. The frontal tectonic de- formation has a stage developed characteristics, all of these have a great signaficance for the sdudy of the frontal New Proterozoic-Lower Paleozoic as well as determine of the crustal shotting mecha- nism during the uplifting of Parmir platean.
