戴屋金矿床位于大瑶山成矿带，其矿化主岩是寒武系浅变质细碎屑岩和板岩。岩石具较高的Au、As、Ag、Sb、Hg 含量。区内广泛发育酸性斑岩类(花岗斑岩、石英斑岩)岩石。斑岩类岩石经历了明显的热液蚀变作用，主要的蚀变作用是硅化、黄铁绢英岩化和绢云母化。蚀变花岗斑岩内存在 Cu、Au、As(Ag)矿化。赋存于变质岩内的金矿化体分为石英脉型矿体和硅化砂岩型矿体。石英脉型矿体受近EW 向褶皱和 NEE、NWW 向断裂控制，硅化砂岩型矿体具层(岩)控特点，矿床的地质地球化学特征和矿体类型表明，该矿床类似于造山型金矿床。

Daiwu gold deposit is located in Dayaoshan metallogenic belt.The host rocks are Cambrian epime-tamorphic microclastic rock and slate,which have high content of Au,As,Ag,Sb,and Hg.The acidic por-phyry rocks (granite porphyry,quartz porphyry)are widely developed in the area.The porphyry rocks have apparently experienced a process of hydrothermal alteration,which mainly includes silicification,beresitiza-tion and sericitization.Mineralization of Cu,Au and As (Ag)is found inside altered granite porphyry.The Au mineralized body occurred inside metamorphic rocks can be divided into quartz vein type ore bodies and si-licified sandstone type ore bodies.The quartz vein type ore bodies are controlled by near EW-trending fold and NEE-and NWW-trending faults,while silicified sandstone type ore bodies have the characteristics of stratabound deposit.The geological and geochemical characteristics and ore-body types of the deposit suggest that the deposit is similar to orogenic type gold deposit.
