| 摘 要： | 在内蒙古大青山地区发育一套高温区域变质岩──麻粒岩，在这高温变质岩内有一系列的糜棱岩带．通过对糜棱岩带中石英的研究，对比深部地壳与浅部地壳石英的变形特点，获得一些新的认识．对石英显微构造、动态重结晶、TEM研究及石英岩组学方面进行了研究，发现石英的塑性变形显著，以缎带石英产出，发育各种塑性变形的显微构造，变形带、波状消光和亚颗粒显著：TEM观察到石英中有直线状的位错．岩组学研究显示出石英高温变形和多期构造叠加的特点．

| Abstract: | A set Of regional metamorphic rocks under high temperature, granu1ite, occur in the Mt. Daqingshan, Inner Mongolia, in which there are some mylonite belts. By the study of tLe quartz of mylonite belts and the comparison of the deformational feature of quartz in deeper crust with upper crust, we have some new understanding. After the microstructure of quarts, dynamic recrystallization, TEM of quartz and petrofabric characteristics are studied, the plastic deformation of quartz has been fOund. The microstructures of striped quartz are defOrmational belt, undulatory extinction and subgrain. Through TEM, the 1ine dislocation in quattz has been found. The characteristics of high temperature deformatbo of quartz and multiple structure have been showed by the petrofabic. |
