摘要
本文根据野外地质调查并综合前人资料,对渭河盆地活动断裂和断块现今活动特征进行了较为详细的论述,对秦岭山前断裂的产状(倾角)提出质疑,提出了北山山前断裂系和秦岭山前断裂系的概念以及运动的差异性,在此基础上,探讨了盆地地震形成模式及其活动特征。
According to field investigation and previous information,this paper expounds the movements of active faults and present fault blocks in the Weihe Basin and challenges the attitude(dip angle) of the Qinling piedmont faults,raising a conception of the movement differentiation between the piedmont fault system of Beishan Mountain and the Qinling piedmont fault system.
