| 摘 要： | 本文在分析了华北东部地堑构造发育特征、地震断层和震源机制等资料的基础上,提出:早第三纪,本区受到了北西—南东向的强烈拉张,其应力场主要受太平洋板块活动的影响;自晚第三纪以来本区主要受北东—北东东向挤压应力场控制。其应力场主要受印度洋板块活动的影响,而太平洋板块活动的影响已相对减弱

DISCUSSION ON THE CHANGES OF CENOZOIC TECTONIC STRESS FIELD IN THE EASTERN PART OF NORTH CHINA |
| |
| Abstract: | On the basis of analysis of the development of grabens, seismogenic faults and focal mechanism, the nature of changes of tectonic stress field in the eastern part of North China during Early-Late Tertiary is studied in this paper. The region under investigation was subjected to a strong NW-SE tension in Early Tertiary. Since Late Tertiary it is mainly controlled by the NE-NEE compressive stress field with the NW-SE running tensile stress field in subordinate place. The stress field here has been |
