| 摘 要： | 黄铁矿是金矿床中重要的载金矿物，对其成分标型进行深入研究可以获得大量矿床成因方面的信息。采用δFe δS、δFe/δS As、(Fe+S) As体系对胶东各类型金矿中的黄铁矿的主微量元素进行了详细研究，得出胶东石英脉型、蚀变岩型和层间滑脱带型金矿成矿期黄铁矿的主微量元素化学成分标型特征。结果表明石英脉型和蚀变岩型金矿成矿期黄铁矿的δFe δS、δFe/δS As、(Fe+S) As体系都具有明显分区特征，这反映了其成矿环境的差异。研究结果证实了该方法适用于胶东各亚类型金矿的研究，并对金矿床中黄铁矿化学成分标型的进一步研究及胶东金矿床的成因和找矿工作具有重要的借鉴意义。

| Abstract: | Pyrite is an ordinary mineral which appears in different types of deposits and it is an important gold-bearing mineral in gold deposits.Through studying the compositional typomorphic characteristics of pyrite,we have achieved much genesis information.This paper studied major and trace elements of pyrite of Jiaodong gold deposits by using δFe-δS,δFe/δS-As and(Fe+S)-As systems and achieved major elements characteristics of Jiaodong gold deposits.The results show that quartz-vein type,altered-rock type and interlayer slippage type of gold deposits in Jiaodong all have its typical characteristics for each distinct ore-forming environment.The result achieved in this paper proves that the compositional typomorphic method of pyrite is well applicable to each sub-type of gold deposits in Jiaodong,and is helpful for studying pyrite compositional typomorphism and for prospecting gold deposits. |
