摘要
以湖北大悟大坡顶矿区内不同类型(岩)矿石的元素分析数据为基础,从多元统计的角度,对微量元素地球化学特征进行了表征。该矿床的矿石可分为石英脉型和蚀变岩型。通过对矿石及围岩的微量元素组成及其与金的相关性的多元统计分析,将微量元素划分为3种组合类型,即:①As、Sb;②Au、Ag、Cu、Pb、Zn;③Mo。第一组合为成矿头晕组合;第二组合为矿体元素组合;第三组合为尾晕组合。
The geochemical characteristics of trace elements in Dapoding gold deposit were investigated based on the trace element analysis of different ore types in the deposit and the multivariate statistical analysis. Quartz-vein type ore and structural altered type ore are the main ore types in this region. The trace element assemblages can be divided into three groups based on the multivariate statistical analysis results, i. e. , ① As, Sb ; ② Au, Ag, Cu, Pb, Zn ; ③Mo. The firstassemblage is ore-forming head-halo elements, the second assemblage is orebody elements and the third assemblage is tail-halo elements.
