摘要
根据成矿作用、成矿环境及矿床特征,红河流域(云南段)砂金矿床可分为残坡积、洪积、冲洪积和冲积4种类型。成矿主要受基底含金地质体、地貌、气候、断层河系及水化学环境等综合控制,哀牢山西侧南段元阳、金平一带最具找矿前景。
According to the metallogenesis, metallogentic environment and deposit characteristics, the gold deposit in the drainage area of Honghe river(Yunnan section) can be divided into 4 types: eluvial-taulus;diluvial;alluvial-diluvial;alluvial.The metallogenesis in mainly cotfrolled by basement rock,geomorphology, weather fault-river and hydrochemical environment.The most potential area is Yuanyang-Jimping area.
