本文以事实为主,阐明本区上地壳结构、活动断层分布、地块的垂直运动。在此基础上研完了区域地壳活动方式,定向分析了主压应力方向,並得到测量资料的验证。 This article is based on facts, illustrating the upper crustal structure, active fault distribution and vertical movement of the block in this area. Based on this, the regional crustal activity patterns were studied and the direction of principal compressive stress was directionally analyzed, which was verified by the measurement data.
