摘　　要：镇沅老王寨金矿属超基性岩接触带金矿。金矿体受地层、构造、基性火成岩的控制。该矿经历了多期成矿作用(沉积—成岩期、热液期、表生期)、多种物质来源(矿源层中分散元素、热源为构造挤压摩擦产生)、以及复杂的成矿热液(深源的岩浆热液、变质热液和大气降水)经反复活化、迁移、聚集和沉淀,形成了如今的矿床。Laowangzhai Au deposit in Shenyuan is a Au deposit in the contact of ultrabasic rock body. The Au ore body is controlled by bed, structure and igneous rock. It has experienced many periods of metallogenesis （sedimentation-diagenesis, hydrothermal, epigenetic）. The ore deposit is formed by the repeat activity, migra-tion, aggregation and precipitation of many material sources （ dispersive element in ore source bed, thermal origin results from the structure compression and friction） and the complicated metallogenetic thermal fluid （deep mag- matic thermal fluid, metamorphic thermal fluid and air precipitation）.
