摘要
本文概述了80年代以来脆性断层运动研究方面的某些成果。介绍了脆性断层带中的一些小构造和显微构造的几何特征以及它们的运动学意义。重点论述了从露头尺度到薄片尺度确定脆性断层运动方向的三种构造判据,既从属裂隙、岩桥构造和方解石e双晶判据。
Some achievements of the kinematic study on brittle faults since 1980' s are summarized in this paper.The geometric character and kinematic significance of some microstructures in brittle faultzones are introduced. The emphasis of the paper is focused on discussing three types of structural criteria for the shear-sense determination in brittle fault zones,i.e. secondary fractures, bridge structures and e twin lamellae in calcite. The discussion provides important information for the study of mi-crostructures and kinematics in brittle fault zones.
