| 摘 要： | 中国PGE（铂族元素）矿床类型分析,PGE（铂族元素）矿床包括Pt,Pd,Rh,Ru,Os,Ir6种元素,它们有着很强的亲“S”性和亲“Fe”族元素性,同时和Mo,Te,As,Sb,Bi等元素也有亲缘关系。这些相关元素在不同介质中,组成不同的元素组合,叫做元素“序列”,共有7个序列,它们对PGE形成有选择性的萃取和捕获能力,叫“萃捕剂”,再加上PGE自身的地球化学差异性,就可能形成多种不同的PGE矿床类型。列举了6个矿床实例,提出了成矿五要素,分析了中国PGE矿床前景,认为成矿和地幔岩初始岩浆密切相关。

| Abstract: | PGEs (Platinum Group Elements like Pt, Pd, Rh, Ru, Os, and Ir) are strongly sulphophile and siderophile. PGEs are also associated with Mo, Te, As, Sb and Bi. Under different conditions, those related elements form different assemblages, which can be named as element sequence. There are seven element sequences, which have selective ability for leaching and capturing different elements of the PEGs. The selective ability may be called function of "leaching and capturing agent". The different leaching and capturing ability with different geochemistry of PGEs form different PGE deposit types. This paper takes six PGE deposits as examples, puts forward 5 factors, which affect formation of the PGE deposits, and discusses the prospect for PEG deposits in China. The author thinks that the formation of PGE deposits is close related to the initial magma of the mantle rocks. |
