摘　　要：水道金矿床是一个与燕山期次火山岩有关的金矿床,明显受东西向韧性剪切带控制。矿体围岩主要是经长期变质变形的古相脉岩(变辉绿岩)及燕山期火山活动产生的各类中酸性脉岩。根据取样分析显示出矿床中变辉绿岩脉、霏细岩脉及次火山隐爆角砾岩脉提供了成矿物质来源,载金矿物(黄铁矿)中的硫元素来自于深源岩浆,成矿作用中的水除了岩浆水外,还有大气降水。The channel gold deposit is a gold deposit related to the volcanic rocks of Yanshan period, which is controlled by the East trending ductile shear zone. The surrounding rocks of the ore bodies are mainly metamorphic rocks （diabase） formed by long-term metamorphism and deformation and various intermediate acid dikes formed during the volcanic activities of the Yanshan period. According to the sampling analysis shows that provides a source of ore-forming material, metadiabase dyke felstone vein and volcano breccia vein deposit, gold bearing minerals （Pyrite） elemental sulfur from the magma, the mineralization of water in magmatic water, and atmospheric precipitation.
