本文通过发育在阿尔金断裂两侧的许多与其成生、活动有联系的帚状构造、入字型构造;横跨阿尔金断裂的河流的河床位移;规模巨大的冲-洪积扇、破坏性地震及现代火山喷发等新构造形迹的研究分析,表明阿尔金断裂是一条自晋宁运动以来,以水平反扭运动为主兼有垂直运动,具有多期活动特点、现今仍在活动的岩石圈深大断裂。不仅是西北地区区域地质构造的分界性大断裂,也是青藏高原与塔里木盆地的地貌分界断裂。断裂本身及其派生构造,对与基性岩有关的矿床和塔里木、柴达木盆地的部分油气资源有明显的控制作用。
In this paper, through the development of many brooms and formations associated with its genesis and activity on both sides of the Altyn Tagh fault, the infill structure, the riverbed displacement across the Altyn Tagh fault, the massive red-alluvial fan, the destructive Seismic and modern volcanic eruptions and other new tectonic research shows that the Altun fault is a since the Jinning movement since the horizontal anti-torsional movement with both vertical movement, with multi-phase activity characteristics, the current activity of the lithosphere Deep fracture. It is not only the demarcation fault of the regional geological structure in the northwest region but also the demarcation of the boundary between the Qinghai-Tibet Plateau and the Tarim Basin. The fault itself and its derived structure have significant control over some basic oil-related deposits and some oil and gas resources in Tarim and Qaidam basins.
