太行山东缘断裂南支断层性质及断层泥K-Ar同位素定年
The character of southern branch fault in eastern marginal fault zone of Taihang Mountain and K-Ar dating of fault gouge
摘要
Abstract
Eastern marginal fault zone of Taihang Mountain is a controlling fault in western marginal of north China Basin, as it has a great meaning to oil-gas reservoir, distribution of earthquake and mineralization since Mesozoic. On basis of detailed research of geometry, kinematics, XRD of fault gouge and K-Ar isotope chronology, we confirmed that the fault zone was a normal and hinge fault,which is composed of a series of normal faults trending NNE. In the longitudinal,it presents left-lateral. The K-Ar dating of syntectonic illite showed that the fault deformed intensely during the time of 113. 42 ±2. 31 Ma. Reactivated during Cenozoic,the fault has formed a series of rift basins.关键词
