摘　　要：红花沟金矿为含金硫化物石英脉型金矿床，主要容矿构造是ＮＮＷ—ＳＮ和ＮＮＥ—ＮＥ向构造裂隙，直接近矿围岩为斜长角闪岩和闪长玢岩．与钾长石化交代重熔花岗岩空间分布关系密切．岩石化学、微量元素、稀土元素及Ｐｂ、Ｓｒ、Ｓ、Ｃ、Ｏ、Ｈ同位素地球化学研究表明，成矿物质可能源于基底太古宇绿岩建造，主要为含透辉斜长角闪岩及其重熔产物，而与中生代花岗岩、火山岩无明显的物质来源联系．为与太古宇绿岩建造有关的交代重熔岩浆热液成因，成矿具同源性，继承性和多期叠加之特征．onghuagou gold deposit is of auriferous sulfidequartz type,whose host structure are the fractures striking NNW to SN and NNE to NE.The wall rock includes amphibolite and diorite porphyrite.The deposit is spacially related to Kfeldspaothized metasomaticremelting granite.Study on lithogeochemistry,microelement,REE and Pb,Sr,S,C,O and H isotopic geochemistry suggests that the oreforming matter is derived from basemental Archean greenstone formation,mainly diopsidebearing amphibolite and its remelting products,but not genetically related to Mesozoic granite or volcanic rocks.The deposit is Archean greestonerelated metasomaticremelting magma hydrothermal origin.The mineralization is characterized by affinity,inheriting and multistage superimposition.
