摘　　要：本文着重总结了滇中中元古界昆阳群中迤纳厂式(铜)铁矿、东川式铜矿、拖布卡金矿主要成矿类型的地质特征和成矿时代,其中因民期火山活动对前两类(铁)铜矿、铜矿的贡献应加以肯定.按照变异相成矿理论提出的“变异相、亲缘相、衍生相”观点和方法,研究其找矿预测方向.In this paper,we have summed up the geological feature and metallogenesis age of main metallogenesis type of Yinachang-type(C)u Fe deposit,Dongchuan-type Cu deposit,Tuobuka Au deposit in Kunyang Group,in which the contributions of(Fe) Cu,Cu deposit before Yinmin period volcanism must be affirmed.The prospecting prognosis direction is studied according to the "variation facies,filiation facies,derivation facies" viewpoint and method resulted from the variation facies metallogenesis theory.
