摘　　要：本文通过上海及其邻区楔形断裂系统中断层泥石英碎砾表面显微溶蚀结构与显微磨损构造的扫描电镜(SEM)研究,分别就显微溶蚀结构所反映的楔形断裂系统之相对活动年代、多期活动性与构造迁移问题以及显微磨损构造形成的应力环境与构造背景问题等展开讨论,从而揭示了上海及其邻区楔形断裂系统中断层泥石英碎砾表面显微溶蚀结构与显微磨损构造的年代学、运动学及动力学构造意义。Through the researches on the solution micro--textues and wearing micro--structures of the quartz fragments of fault gouge from the wedge--shaped fracture system in the neighbourhood of Shanghai by way of SEN, the paper discussed the following problems: 1. the relative age of faulting, the multi--phase activity of faulting and the migration of faultieg; 2. the stress environment and tectonic background, thus revealing the tectonic implications of the solution microtextures and wearing microstructures of the quartz fragments from the wedge shaped fracture system
