摘要
五台山-恒山绿岩带型金矿床可分为同构造晚期初生型和构造期后再生型金矿床二类。不同类型金矿床产出的构造环境、地质地球化学特征明显不同。初生型金矿床空间分布主要受NEE向的韧性剪切带控制,而构造期后再生型热液金矿床受控于NNW向的脆性断裂。金矿的成矿期有三期:新太古代末期、古元古代晚期和燕山期。
Wutaishan-Hengshan greentone belt gold deposits can be grouped into two types:late-syntectonic pritnary deposits and Post-tectonic regenerated deposits. It is evident difference of metalbeenic geobeical envirorunent and geological-geochemical characters between two types.The spatial distribution of primary deposits is meinly controlled by NEE-trended ductile shear sone, the POSt-tectonic regenerated gold depolsits related with subvolcanic rock are controlled by NNW-trended brittle fracture. The metallogenic epoch may be divided into three phases: late Neoarchean, late Paboroterozoic and Yanshanian.
