在不同的温压条件下，构造带岩石中的石英发生脆-塑性或塑性变形，在晶内产生各种光性异常，即在光学显微镜下可见波状消光、带状消光、变形纹、亚颗粒等光性特征。文章通过对北秦岭伏牛山构造带内构造变质岩中石英的光弹性现象、动态重结晶等特征的细致观察及显微变形测量，分析了石英光性特征与应力变化、应力方位、应力大小以及应变速率之间的关系，以此探索光性特征与构造变形之间的对应关系。

In different temperature pressure conditions ,the quartz in the tectonic belt rocks shows brittle-plastic or plastic deformation ,producing a variety of optical abnormalities within the grain ,namely the undulatory extinction ,strip matting ,deformation pattern ,subgrain and other optical characteristics under an optical mi-croscope .The photoelastic phenomenon ,dynamic recrystallization and other characteristics of the quartz in tectonic metamorphic rock in Funiushan tectonic belt ,Qinling orogenic belt are observed and the microscopic deformation measurement is conducted .The relationship between the quartz optical characteristics and the stress changes ,stress orientation ,stress magnitude and strain rate is studied to explore the correspondence between the optical characteristics and tectonic deformation .
