| 摘 要： | 本文主要研究断层泥中新生的粘土矿物特征,并研究断层泥中石英碎砾表面溶蚀的显微形貌结构特征。粘土矿物以X-射线衍射分析为主,石英碎砾则利用扫描电子显微镜对其显微形貌结构进行分析,并根据石英表面溶蚀的形貌特征来探讨断裂活动的相对年代

| Abstract: | In this paper, characteristics of neogenic clay minerals and micro-surface texture of quartz fragment in fault gouge are discussed. Clay minerals are analysed mainly by X-ray diffraction, whereas miero-surface texture of quartz fragments is studied by SEM. The relative age of faulting is determined with the analysis of corroded surface texture of quartz fragments. |
