| 摘 要： | 根据成矿作用、成矿环境及矿床特征，金沙江流域（云南段）砂金矿床，可划分为：残坡积、洪积、冲洪积、冲积和冰碛等五种类型。成矿主要受碰撞带、深大断裂、大断裂及其派生断裂、基底岩石、地貌、水质和水化学环境等综合控制。以巨甸－大具及中江街－金江街两片区最具有找矿前景。

| Abstract: | According to the metallogenesis, metallogenetic environment and deposit characteristics, the gold placer in the drainage area of Jinsha river(Yunnan section) can be divided into 5 types: eluvial talus; diluvial; alluvial diluvial; alluvial and drift. The metallogenesis is mainly controlled by collision zone, deep fault, large fault, basement rock, geomorphology, water series and hydrochemical environment. The most potential prospecting areas are Zhongdian Daju and Zhongjiangjie Jinjiangjie. |
