摘　　要：研究区经历了前加里东期、加里东期、晚印支期、燕山期、喜马拉雅期等不同时期构造变形,并形成了不同矿体构造变形组合。基于构造变形时间基础,对不同尺度构造变形组合空间分布,及其叠加、改造、包容关系,建立区内构造变形序列,结合沉积、矿物的矿化作用和变质作用的综合分析,进一步建立研究区的综合地质事件表。The study area has undergone structural deformation in different stages such as pre-Caledonian,Caledonian,Late Indosinian,Yanshanian and Himalayan,and formed different structural deformation assemblages of ore bodies.Based on the time basis of tectonic deformation,the spatial distribution of tectonic deformation associations at different scales and their superposition,transformation and inclusion relations,the tectonic deformation sequence in the study area is established,and the comprehensive geological event table is further established by combining the comprehensive analysis of sedimentation,mineralization and metamorphism.
