本文详细论述了阿尔金山北缘断裂带的空间展布和基本特征,探讨了断裂带的东延、平移滑动以及断裂带与地震活动关系,指出:阿尔金山北缘断裂带为一活动历史悠久、具左旋平移滑动特征、切割地壳较深的深大断裂带,过大坝后,继续向东延伸,到宽滩山一带进入金塔盆地而消失。该断裂带为一转换断层,向左平移滑动的距离最大达120公里,全新世以来活动强度不大,地震活动的频度较低。
This paper discusses in detail the spatial distribution and basic characteristics of the northern margin of the Altun Mountains, and discusses the relationship between the eastward extension of the fault zone, the translatory slip and the seismic activity. It is pointed out that the northern margin of the Altun Mountain has a long history of activity, With a left-lateral translational sliding feature, the deep crust with deep crustal faulting is cut. After passing through the dam, it continues to extend eastwards and disappears into the Quinta Basin by way of Mt. The fault zone is a transitional fault with a distance of up to 120 km to the left for translational movement. Since the Holocene, the activity intensity was low and the frequency of seismic activity was low.
