摘　　要：矿体产出受深大断裂派生的剪切断裂及脆—韧性剪切带控制明显,矿床形成具多期、多阶段和多源特征。通过对成矿流体和成矿机理的研究,笔者认为该矿床是较典型的构造蚀变岩型金矿床。The orebody occurrence is evidently controlled by the shear fault and brittle-ductile shear zone. And the formation of ore deposit is characterized by multiperiod, multistage and multipie genesis, According to the study of metallogenetic fluid and metallognetic mechanism, we think this ore deposit is a typical Au deposit of structural altered rock type.
