| 摘 要： | 喀喇昆仑断层位于我国新疆、西藏和阿富汗、克什米尔之间,是亚洲大陆中部一条巨型的右旋走滑断裂带,长约1000km,呈北西向展布,十分醒目。喀喇昆仑断层和阿尔金断层形成一个巨大的挤出构造,使青藏高原向东运动,对东亚的新构造和地震活动具有重要的控制作用。木吉-塔什库尔干盆地是公格尔山和慕士塔格山西侧一条串珠状断陷盆地带,东西两侧发育系列山前活动断裂,主要表现为正断层。这里曾发生多次强震活动,3条地震形变带(地震断层)已被发现。塔什库尔干断裂带呈北北西走向,是喀喇昆仑断层北部的一条分支

| Abstract: | The Karakorum fault, a major right lateral strike-slip falut in the central Asia is located among Xinjiang, Tibet, Afghanstan and Kashmir, trending NW, with a total length of about 1000km. The Karakorum fault and the Altun Tagh fault creat a large escaping tectonics, which makes the Tibet Plateau moving eastward and has a control on the neotectonics and seismicities of the eastern Asia. The Muji-Taxkorgan basin, a string-like rifted basin is distributed along the western margin of Kongur and Muztagata Mts. A series of active faults lie on the eastern and western margins of these basins. These active faults are characteristic of normal fault. There have been a lot of strong earthquakes and three seismic deformation zones have been found. The Taxkorgan fault is a northern segment of the Karakorum fault, extending NNW. |
