摘要
采用电子探针对贵州某卡林型金矿微细金矿物化学成分进行详细的定性定量分析，发现Ａｕ、Ａｇ、Ｓｎ的化学成分呈规律性变化，其含量变化范围分别为２．７６％～９５．８８％、０．４３％～９．１５％、３．６９％～８８．０９％。经统计分析，Ａｕ与Ａｇ和Ｓｎ呈明显的负相关关系，具有类质同象成分特征，初步确定为金银锡系列矿物。
Through detailed qualitative and quantitative analyses of the chemical composition of the finegrained mineral from a certain typed gold deposit in Guizhou by means of electron microprobe,the variation regularity of the chemical composition of Au,Ag,Sn are found .The variable ranges of their content are 2.76%9588%,0.43%915%,369%8809% respectively.According to statistical data,the evident negative correlations present among Au,Ag,Sn which offer characteristics of isomorphism.As a reault,the finegrained gold mineral from that gold deposit in Guizhou Province is preliminary ascertained as Au-Ag-Sn series mineral.
