摘要
本文通过对断裂构造岩显微构造特征的研究,进而对石英变形纹及光轴系统测量统计,进行岩组动力学分析,重建了断裂活动时的应力场特征及演化。并对断裂空间分布,断裂性质,运动方式、方向,生成环境及活动时期等作出推论。从而验证和进一步揭示了断裂的宏观构造特征。
Through the studies on the microstructural features of the tectonite, statistical analyses of the quartz deformation lamellae and optical axes, as well as petrofabric dynamics analyses, the authors demonstrated the characteristics and evolution of stress field alogng the fault zones, and deduced the distribution, nature, movement mode and sense, tectonic environment and relative dete of the fault zones. Thus. the authors testified and revealed the macrostructural features of the fault zones concerned.
