山西省金矿地质特征

阐明金矿成矿地层、岩浆岩、构造等地质条件．指出早元古界前和中生代燕山期以来两个重要成矿期．内生、变质、砂金、伴生金矿床类型均有．目前发现的金矿床类型以岩浆热液型和火山一次火山热液型为主；绿片岩含金石英脉-绢片岩型、含金硅铁岩型和变质砾岩型等变质热液型金矿点金矿化点已多处发现．五台山—恒山区是重要的金矿成矿区．

Geological Characteristics of Gold Deposits in Shanxi

Such geological conditions of gold deposits as ore forming strata, magmatic rock and structures are discussed. lt is pointed out Pre -Proterozoic Era and Yanshan Period of Mesozoic Era are the two important periods of gold mineralization. Such gold deposits as endogenetic, metamorphic, placer and associated types are found. The found gold deposks are mainly magmatic hydrothermal type and volcanic-subvolcanic type. lt might be noticed that the metamorphic hydrothermal gold mineralization of quartz vein-sericite schist type in green schists, siliceous ferruginous type and meta-conglomerate type are widely discovered. Mt. Wutai-Mt. Hengshan area is an important gold minerogenetic one.
