【摘要】 通过对区内中强地震震例、地震构造背景、地壳深部构造、居里等温面埋深变化及地震空间分布特征的分析，提出区内中强地震潜在震源区判别的主要标志，重点讨论了区内中强地震与中地壳层内的深变质岩系和居里等温面的关系。更多还原

【Abstract】 The main discriminative criteria of potential focal area of moderate earthquake in researched area are proposed, based on the data of seismicity. seismotectonic background, crustal deep structure and Curie isothermal surface depth. The relation of moderate earthquake in researched area with strong metamorphism rock system and Curie isothermal surface is discussed.更多还原
