本文着重从重磁场特征结合地表构造、震中分布特点,对重磁场与深部构造、地震的关系进行探讨,认为地震多数发生在本区重磁场具有一定规模、梯度大的梯级带内,且主要发生在梯级带的轴向转换、转折、拐弯部位。它反映了本区深部构造的主要骨架呈北东向、东西向两种构造体系复合部位或北东向深大断裂带与多组构造交切部位。并结合本区近期流动重、磁测量资料,进一步确定可能存在的地震危险区。
This paper focuses on the characteristics of gravity and magnetic field combined with the surface structure and epicenter distribution characteristics of heavy and magnetic field and deep structure and the relationship between the earthquake is discussed that most of the earthquakes occurred in the region with a certain scale of heavy magnetic field gradient large gradient zone, Cascade with the axial conversion, turning, turning parts. It reflects that the main structure of the deep structure in this area is north-eastward and east-west structural zones or north-easterly deep fault zones and multiple sets of structural intersections. Combined with the recent mobile gravity and magnetic measurement data in this area, the possible seismic hazard zone may be further determined.
