摘要
锑矿床和微细浸染型金矿床中辉锑矿的稀土元素地球化学指标对比分析，表明锑矿床中辉锑矿稀土元素含量低于金矿床中含金辉锑矿。锑矿床中辉锑矿的ＬＲＥＥ／ＨＲＥＥ小于金矿中含金辉锑矿。从辉锑矿的多元素地球化学特征的分析，认为金矿床中辉锑矿主元素锑含量较低，富含金、银、砷杂质元素，而锑矿床中辉锑矿的锑含量较高，金、银、砷含量较低。利用辉锑矿稀土元素及杂质元素地球化学特征，可间接或直接评价微细浸染型金矿床。
Geochemial characteristics of REE and impurity elements of antimonite in antimony and micro disseminated gold deposits are studied in this paper and analysed.It shows that the differences of REE geochemical indices exist between antimony and micro disseminated gold deposits.The analysis of impurity elements of antimonite displays that antimony principal element content of antimonite in gold deposits is lower than that in antimony deposits,but richer in Au、Ag、As.Whereas the antimony content of antimonite in antimony deposit is higher than that of gold deposit,but poor in Au、Ag、As.The above features may be used to evaluate the perspective of micro deseminated gold deposits.
