摘要
本文初步研究了新疆独山子山前活断层、活褶皱构造。这些表层构造有着不同性质的地表变形,是多次古地震活动的反映。文中将这些古地震遗迹分为四期,并计算了该断层带的地震复发周期和平均位移速率。
This paper has studied active faults and folds on Dushanzi piedmont. which show that there have been repeatedly pa-leoearthquakes in Dushanzi, Xinjiang Uygur Autonomous Region. These active structures are surface deformation with different property formed in the different place of fold during the development of Dushanzi anticline since the period of neotectonic movement. These paleoearthquake traces are divided into four events whose recurrence intervals and slip rates are evaluated.
