摘　　要：云南蝉战河铜矿床具有典型的砂岩型自然铜矿特征和玄武岩型自然铜矿特征。本文在分析铜矿床的区域构造演化、地层、构造等地质特征的基础上,结合蝉战河铜矿床的总体特征,分析该矿床的矿床成因,并建立其成矿模式。最后与典型的美国基韦诺自然铜矿床的成矿模式进行对比,对滇黔地区玄武岩型铜矿床的找矿有重要启示。Chanzhanhe copper deposit has the native features of sedimentary sandstone copper deposit and basalt copper deposit. Based on the analysis of regional evolution,strata,structure,combined with the geolog- ical feature of Chanzhanhe copper deposit, the paper has discussed the deposit genesis,and has built the metallogenic model. With the comparison of the metallogenic model of Keweenawan nature copper deposit,it is an important revelation for the exploration of basalt copper deposit in Yunnan and Guizhou Provinces.
