有关地震成因的各种假说和震源构造理论模型与实际的震源破裂过程之间缺乏直接联系。某些震源参数的确定以及地震成因的基本理论至今尚未从根本上解决。对地震活动规律性的认识和地震预测工作仍然处在统计分析和积累经验的过程。因此,近年来不少地震地质学家、地球物理学家以及实验岩石学家开始转向震源实体的地质研究。从暴露的中、下地壳岩石中,寻找地壳较深层次上曾经发生地震破裂的遗迹或“地震化石”。通过对地震过程的产物、震源破裂的构造样式、震源区的构造背景和介质条件等进行实际观察和分析研究,从中获取一批有关的构造地质学、岩石学、几何学和物理力学的参数,并把它们与过去的认识加 There is a lack of direct connection between the various hypotheses on the causes of earthquakes and theoretical models of hypocenter tectonics and the actual process of source disintegration. The determination of some source parameters and the basic theory of earthquake origin have not yet been fundamentally solved. The regularity of earthquake activity and earthquake prediction are still in the process of statistical analysis and accumulation of experience. Therefore, in recent years, many seismic geologists, geophysicists and experimental rock scientists have turned to the geological study of focal entities. From the exposed middle and lower crustal rocks, look for ruins or “seismogenic fossils” that once occurred at deeper levels of the earth’s crust. Through the actual observation and analysis of the product of the earthquake process, the tectonic style of the source rupture, the tectonic setting of the source area and the medium conditions, a series of relevant tectonic geology, petrology, geometry and physical mechanics parameters are obtained. And put them with the past knowledge plus
