摘　　要：大水式金矿床是近年来发现的一个新类型金矿,其矿化特征独特、埋藏浅、品位高、化学成分简单、易采选、具有很高的经济价值。本文通过对该矿床的地质特征、成因等和周边的金矿床进行了对比分析认为,大水式金矿是构造—岩浆—热液活动体系的系列演化产物。The collection of geological information and access to relevant literature summed up the Dashui- type gold deposit is a new type of newly discovered gold mine, which its mineralization unique, shallow buried, high grade, chemical composition is simple and easy to select. By comparison to the gold deposits of surrounding area, it showes that Dashui-type gold deposits in the ore-forming process has a unique feature of tectonic-mag- matic-hvdrothermal svstem, the product of a series of evolution.
