摘要
本文依据地质资料、水系统计资料、震源机制解、地震等烈度线及断层位移测量、地应力测量结果等,研究了渭河盆地构造应力场演变,讨论了盆地形成机制。在此基础上,结合盆地新生代沉积特征,对其发展演化阶段进行了初步划分。
According to the data of geological investigation, the strike statistics of the river system, focal mechanism solutions, seismic intensity line, fault displacement measurements, geostress measurement and so on, this paper deals with the structure stress field evolution and the formation mechanism of the Weihe basin.On this basis and combining with the sedimentary characteristics of the Cenozoic in the basin, the writers have divided the stages of the development and evolution of the basin.
