摘要
当前人们对一轴晶矿物光轴优选方位的动力学分析看法不一。本文联系野外实际情况、显微构造标志及有关实验理论资料,对密山—抚顺断裂带西南段部分岩石的石英、方解石的光轴优选方位判读应力方位,得到了与野外宏观分析及显微构造分析相一致的结果。这不仅对该断裂带区域构造应力场的研究增加了资料,同时亦为石英、方解石光轴岩组动力学分析的探讨提供了参考实例。
It is in dispute at present to explain uniaxial crystal mineral optic axis pre- ferred orientation for dynamic analysis.Relating the field informatim,microstructure marks and some experimental data,this paper discussed the stress orientation by means of quartz and calcite optic axis preferred orientation of Mishan-Fushun fault zone.The result is in keeping with what field survey and microstructure study.The discussion not only increases a few data to study the fault stress field,but also affords us reference ma- terial to research on fabric dynamic analysis of quartz and calcite optic axis preferred ori- entation.
