本文主要研究了北北西—南南东向喀喇昆仑断裂的几何学、运动学、水平位移量、活动时间及其变形方式。在断裂带内产出的主要构造形态有:不对称耦曲、s-C组构、长石和石英斑晶、多米诺构造、剪劈理和断层等,它们是构造活动的产物,并从中判断出右旋走滑运动,伴随走滑变形发生了绿片岩至角闪岩相、甚至混合岩化的变质作用,出现了多硅白云母和其它一些应力矿物,显示变形压力较高。糜棱岩带的产出与喀喇昆仑断裂活动密切相关。同位素测年资料表明
This paper mainly studies the geometry, kinematics, horizontal displacement, active time and deformation of the North-Northwest-South-East Karakoram fault. The main tectonic modes in the fault zone are asymmetric coupling, sC structure, feldspar and quartz porphyry, domino structure, shear cleavage and fault, which are the products of tectonic activity, from which the dextral With the strike-slip deformation, episodes of greenschist to amphibolite and even metamorphic metamorphism occurred along with strike-slip deformation. Silicalite and some other stress minerals appeared, showing higher deformation pressure. The mylonite zone is closely related to the Karakorum fault activity. Isotope dating data indicate
