| 摘 要： | 提出了一种新的发震构造型式－转换破型型。其特征是地震不发生在主干断裂和共轭断裂面上，而是在其两侧一定距离的岩块中；发震断裂不与其平行而是成一定的交角；震源机制解的三个力轴与造力应场相对应的三个力轴不一致，而是有规律地旋转了一定有角度。

| Abstract: | New type of seismogenetic tectonic pattern-transform fracture type is discussed in this paper. These earthquakes occured neither on major fault, nor on conjugate fault, but on rock mass at a distance from major fault and conjugate fault. A long axis of seismic intensity oftenintersect with them and the surface faults don't occur obviously. Two nodal in focal mechanism make a certain angle with them. Focal stress field differs from the tectonic stress field. If the axis of focal stress field is changing the tectonic stress field can be renewed. It is the basic characteristics of the transform fracture type for seismogenetic tectonic pattern. |
