摘    要：东方红金矿区断裂构造发育,并为主要控矿地质条件。北东向断裂构造为压扭性,沿断裂构造发育的蚀变带以硅化、绿泥石化、碳酸盐化等矿物组合为主,构造原生晕富Au,贫Cu、Pb、Zn,并控制土壤测量Au元素异常浓集中心的分布;北西西向断裂构造为张扭性,沿断裂构造发育的蚀变带以黄铁矿化、方铅矿化、高岭土化等矿物组合为主,构造原生晕贫Au,富Cu、Pb、Zn,并控制土壤测量Cu、Pb、Zn等元素异常浓集中心的分布。工程揭露结果表明,Au矿化蚀变带沿北东向断裂构造分布,而Pb等矿体受控于北西西向断裂构造带。

Abstract: Fault structures in Dongfanghong gold deposit develop well,and they are the main ore-controlling geological conditions.The NE-trending faults are compression-torsion type,and the alteration zones developing along the faults are mainly silicification,chlorite,carbonatization and other minerals.The structural original halo is rich in Au,and poor in Cu,Pb,Zn,and it controls the distribution of soil Au anomalies concentration centers.NWW-trending faults are tension-torsion type,and the alteration zones developing along the faults are mainly pyrite,galena,kaolin and other minerals.The structural original halo is poor in Au,and rich in Cu,Pb,Zn,and it controls the distribution of soil Cu,Pb,Zn anomalies concentration centers.The results show that the Au mineralized alteration zone distributes along the NE trending fault structure,while Pb and other orebodies are controlled by NWW-trending fault zone.
