天水地震区地壳结构特征

THE FEATURES OF CRUSTAL STRUCTURE IN TIANSHUI EARTHQUAKE AREA

摘要:

本文在对天水地震区人工地震测深资料解释的基础上,系统地分析和归纳了该区基底特点、深部速度结构特点、断裂特点和大地构造特点,获得了对该区由浅到深、从地球物理到地质、从地壳结构到大地构造及其形成较全面较深刻的认识。

Abstract:

Based on the interpretation of DSS in Tianshui earthquakes area,the features of basement,deep velocity structure,fault and tectonics are analysed and sumed up.More profound,systematic and comprehensive understanding about this area from shallow to deep,from geophysics to geology,from crustal structure to tectonic and its formation are obtained.
