| 摘 要： | 通过对呼和浩特市大青山地区糜棱岩带中石英的显微构造、动态重结晶、ＴＥＭ及石英岩组学方面的观察研究，发现石英的塑性变形显著，以缎带状石英产出，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位错，岩石组学研究显示出，石英具有高温变形和多期构造叠加的特点。

| Abstract: | With the study on quartz of mylonite belts occur in Mt.Daqingshan by means of the microstructure,dynamic recrystallization,TEM and petrofabric,the plastic deformation of quartz has been found.The microstructures of spriped quartz are deformational belt, undulatory extinction and subgrain.With TEM,the line dislocation in quartz has been found.The characteristics of high temperature deformation of quartz and multiple structue have been showed by the petrofabric. |
