基于多元统计学的大尹格庄金矿床深部地球化学找矿标志研究

Research on deep geochemical prospecting indicators of Dayingezhuang Gold Deposit based on multivariate statistics

在大尹格庄金矿床深部勘查钻孔ZK4孔地球化学测量的基础上,通过应用多元统计学中的相关分析、聚类分析和因子分析,探讨与Au成矿有关的深部地球化学找矿标志。研究结果表明:Hg可做为该矿床与Au成矿有关的通用指示元素;Au和Ag的相关系性最高,Ag可作为矿区内找金的指示元素;因子分析中公因子为典型的热液矿床元素组合;Au-Ag-Bi是该金矿床成矿预测最有效的指示标志。

Based on geochemical survey of borehole ZK4 in deep Dayingezhuang Gold Deposit, the correlation a nalysis, cluster analysis and factor analysis in multivariate statistics are applied to explore the deep geochemical indicators associated with Au mineralization, The analysis holds that Hg can be used for the deposit as the universal indicator element associated with Au mineralization; Au and Ag are of the highest correlation coefficient; Ag can be used as the indicator element within the mining area for gold; According to the factor analysis, the public factor is a typical hydrothermal deposit elements combination; Au-Ag-Bi is the most effective indicator for the prediction of gold deposits.
