摘　　要：云南省红牛铜多金属矿床矿石矿物主要为金属硫化物之黄铜矿、黄铁矿、磁黄铁矿、磁铁矿,通过对成矿地质背景、部分矿体特征、主要矿物特征、金属矿物共生组合关系、矿物生成顺序及成矿期次分析研究,该矿床经历了岩浆期成矿、岩浆期后热液成矿、表生成矿三期成矿作用,矿床成因类型为受岩浆活动控制的矽卡岩型铜矿床和受构造破碎带控制的中-低温热液型铜矿床及表生矿床。The ore minerals of Hongniu copper polymetallic deposit in Yunnan Province are mainly chalcopyrite,pyrite,pyrrhotite and magnetite of metal sulfide.Through the analysis study on metallogenic geological setting,characteristics of some ore bodies,main mineral characteristics,symbiotic association relationship of metallic minerals,period of mineralizing and mineral formation sequence,the deposit has experienced three stages of mineralization:magmatic mineralization,postmagmatic hydrothermal mineralization and supergene mineralization,and the genetic types of the ore deposit include skarn copper deposit controlled by magmatic activity,medium-low temperature hydrothermal copper deposit controlled by tectonic fracture zone and superficial deposit.
