中文摘要：

大量的同位素年代学证据表明（古）阿尔金断裂带可能形成于三叠纪，后又经历了侏罗纪、白垩纪的强烈左旋走滑活动，自印度板块与欧亚大陆碰撞后阿尔金断裂再次活动。主要的走滑活动发生在：（1）245～220Ma；（2）180～140Ma；（3）120～100Ma；（4）90～80Ma；（5）60～45Ma（6）渐新世至中新世；（7）上新世至更新世以及（8）全新世。沿阿尔金断裂带，伴随左旋走滑活动形成一系列的逆冲断裂和正断裂，反映走滑过程中伴随隆升作用的存在，并且形成自北向南包括祁连山、大雪山、党河南山、柴北缘山、祁漫塔格山和昆仑山，表明阿尔金断裂带制约着青藏高原北部的生长和隆升。阿尔金断裂带东、西两端的白垩纪和新生代火山活动是断裂走滑活动的响应。

英文摘要：

Initial sinistral strike-slip shearing of the Altyn Tagh fault system occurred in the Triassic, and was intensely reactivated in Jurassic and Cretaceous time following the collision between the Indian and Eurasian plates. This conclusion is based on multiple isotope dating of minerals in ductile shear zones along the fault. Main displacements of the fault occurredbetween （1） 245-220 Ma, （2） 180-140 Ma, （3） 120-100 Ma, （4） 90- 80 Ma, （5） 60-45 Ma, and during （6） the Oligocene-Miocene, （7） the Pliocene-Pleistocene, and （8） the Holocene. The strike-slip displacements resulted in thrust faultings and normal faulting along the Altyn Tagh fault system, and were responsible for the rise of a series of mountain ranges, including the Qilian , Daxueshan , Danghenanshan , North Qaidam , Qiman Tagh , and , Kunlun mountains. These relationships demonstrate that the Altyn Tagh fault system constrained the growth and rise of the northern Tibetan Plateau. Cretaceous and Cenozoic volcanic activities at both northeastern and southwestern ends of the Altyn Tagh fault system were the results of the reactivation of the faults.
