引言 对褶曲和断层等地质构造的分析,目的在于查明其形成过程,最终弄清楚作为这些构造起因的构造运动发展史。如果对这些构造进行定量分析,就可以在了解地壳内部的应力分布及其变迁方面取得重要的手段。具体地讲,就是根据从那些形变现象所推导出的应变椭球体的分析来恢复构造应力场并查明其时间的变迁过程。 Introduction The analysis of geological formations such as folds and faults is aimed at identifying its formation process and finally clarifying the history of the tectonic movement that is the cause of these structures. If these structures are quantitatively analyzed, important means of understanding the stress distribution inside the crust and its changes can be obtained. Specifically, it is based on the analysis of strain ellipsoid deduced from those deformation phenomena to restore the tectonic stress field and ascertain the changing process of time.
