深部热流体上涌对天水强震区深部发震环境形成演化过程的影响作用

EFFECT OF DEEP SUBSURFACE HOT FLUID UPWELLING ON FORMATION AND EVOLUTION OF DEEP STRUCTURE IN TIANSHUI STRONG EARTHQUAKE AREA

摘要:

通过与肯尼亚Gregory地堑的深部构造的对比分析,本文研究了天水强震区深部发震环境的形成演化过程及其主要特征,探讨了深部热流体上涌在该地区深部发震环境形成演化过程中所起的重要作用,为进一步研究该地区前兆形成机理打下基础。

Abstract:

Comparing with the deep structure of Kenya Gregory rift, the formation, evolution process and characteristics of deep structure of Tianshui area are researched. In our view, the upwelling of the deep subsurface hot fluid has greatly affected the formation and evolution process of the deep structure in the area. The results are helpful in analyzingthe mechanism of the seismogenesis.
