摘要
利用相关分析、聚类分析、因子分析等多元统计方法,对高松山金矿床岩(矿)石微量元素地球化学特征的.研究表明,Au与Ag、As、Sb、Pb等中低温元素具有较强的相关性.依据元素的共生组合及相关性特征,将微量元素分为5个组合类型:Au、Ag、As、Sb、Pb、Mo;Co、Ni、Mn、-Sn;Cu、W;Hg、Bi;Zn、Sn.对矿体轴向上微量元素分布特征研究表明,在不同标高上矿体微量元素出现前缘晕与尾晕指示元素、近矿晕与尾晕指示元素、前缘晕与近矿晕指示元素相互叠加的现象,显示出矿区内成矿作用复杂、具有多次矿化叠加的特征.
With multivariate statistical analysis, the trace element geochemistry of the Gaosongshan gold deposit in Xunke County, Heilongjiang Province is studied. The result shows that the element of Au is closely related to Ag, As, Sb and Pb in the gold deposit. Based on the association and correlative character of elements, the trace elements can be divided into five assemblages, i.e. l） Au, Ag, As, Sb, Pb and Mo; 2） Co, Ni, Mn, and -Sn; 3） Cu and W; 4） Hg and Bi; and 5） Zn and Sn. The variation of trace elements in vertical direction indicates that, in different elevations of gold orebody, there exits superimposition of the indicator element between head-halo and tail-halo, orebody and tail-halo, headhalo and orebody, respectively. All the characteristics suggest that the metallogenic process in the orefield very complex, with superposition of mineralization.
