摘要:
安王山金多金属矿床位于北秦岭成矿带中段。矿区内发育3条北西向强变形带，其内已圈定7条矿体，矿石类型以构造蚀变岩型和含金石英脉型为主，与成矿关系密切的围岩蚀变有硅化、绢云母化、早期碳酸盐化、黄铁矿化等。矿体产于北西向强变形带中，并受到北东向断裂控制的石英正长岩脉和含硫化物石英脉的叠加改造，初步分析认为矿床成因类型为岩浆热液型。北西向强变形带、石英正长岩脉及地表强烈蚀变组成的“红带”是重要的地质找矿标志，Au、Ag、As、Pb、Zn、Cu等元素形成的综合异常为地球化学找矿标志。

Abstract:
The Anwangshan Gold Polymetallic Deposit is located in the middle part of the North Qinling metallogenic belt.Three NW trending strong deformation zones have been found in the deposit,among which 7 ore bodies have been delineated.The ore types are mainly structural alteration type and gold-bearing quartz vein type.The wall rock alteration closely related to mineralization is silicification,sericitization,early carbonatization,pyritization and so on.Ore bodies are found in the NW strong deformation zone,and reconstructed by quartz syenite vein and sulfide-bearing quartz vein controlled by NE fracture.The preliminary analysis is that the genesis of the mineral deposit is magmatic hydrothermal type.The NW strong deformation zone,the quartz syenite vein and the "red zone" composed of intense surface alteration can be used as important prospecting criteria.The composite anomalies formed by the elements such as Au,Ag,As,Pb,Zn,and Cu can be used as geochemical prospecting criteria.
