摘要
论述了构造岩浆活化与富锡、铜矿体形成的地质条件。作者将个旧矿区富锡、铜矿体分为两大类:①岩浆改造富化型;②岩浆迭加富化型。从控矿地质条件和矿物包裹体成分、同位素组成论述了两类矿体多因复成特征。分析了构造岩浆活化与富锡、铜成矿的关系。
This paper demonstrates the relation between tectono-magmatic activation and geological conditions of development of Sn-Cu-rich orebodies. Based on these, Sn-Cu-rich orebodies in the Gejiu mining area are divided into two types: transforming-richening type and superimposition-richening type. Finally, from ore-controlling geological conditions, mineral inclusion composition and isotope composition, the author demonstrates polygenetic magmatic activation and Sn-Cu-rich orebodies.
