摘　　要：岔河锡矿产于晋宁期摩挲营花岗岩与前震旦系会理群天宝山组大理岩及其顶板变辉绿岩接触带中 ,属岩浆气成 -高中温热液成因的矽卡岩型锡石硫化物矿床。地球化学特征表明 ,是成矿物质来源于地层和花岗岩的最古老锡矿床之一。文章介绍了矿床的地质地球化学特征 ,讨论了矿床的成因模式。Chahe tin deposit is one of the oldest deposits and was formed during Jinning Movement Period.It belongs to magmatic hypothermal to mesothermal deposit.On the basis of the study of geochemistry,we realized that the source of mineralization elements came from strata and granite.This paper also discussed the feature of geochemistry and the genetic model of the deposit.
