摘　　要：研究区位于扬子准地台-川滇台背斜-滇中中台陷-元谋凸起的西南部,区内地质构造复杂,岩浆活动和变形变质作用广泛,矿化普遍,以往地质找矿工作研究程度较低,具有较大的找矿潜力。本文在总结大姚县秀水河铜金矿地质地球化学特征,分析研究成矿作用的基础上,试图建立符合实际的成矿规律,以期为该区开展找矿工作提供参考。The study area is located in the southwestern part of the Yangtze Paraplatform-Sichuan and Yunnan Platform Anticline-Central Yunnan Platform Depression-Yuanmou Uplift.The geological structure in the area is complex,with extensive magmatic activity and deformation metamorphism,and widespread mineralization.Previous geological exploration work in the study area has a relatively low degree of research and has great potential for mineral exploration.On the basis of summarizing the geological and geochemical characteristics of the Xiushuihe copper-gold deposit in Dayao County and analyzing the mineralization process,a realistic metallogenic law was attempted to be established,in order to provide reference for prospecting work in this area.
