摘要:

水晶屯金矿区2个深部验证钻孔岩心样品的11 种元素分析结果表明,各个矿化带中Au、Bi、Ag 高度相关,As、Hg 的相关性也很高。在ZK1钻孔的509~517m矿化段,ZK2的380~420m矿化段,Au、Ag、Cu、Pb、Zn、As、Sb、Bi 、Hg 的相关性非常高,而与Mo、W呈负相关关系,表明该段为矿化富集带。与之相反,在非矿化段中各元素的相关性不是太好。相关分析结果表明,元素Bi、Ag可作为该矿区深部化探找金的指示元素,预测靶区处于隐伏矿体的头部,深部找矿潜力很大。

Abstract:

The Hierachical Cluster analysis of eleven elements in two deep validated drill holes in Shuijingtun gold deposit indicates that Au-Bi-Ag are highly correlated and As-Hg are also highly correlated in each mineralized belts.In the ore zones between 509 and 517 meters of ZK1 and between 380 and 420 meters of ZK2,the correlation of Au-Ag-Cu-Pb-Zn-As-Sb-Bi-Hg is very high.However,they have negative relations with Mo and W.Therefore,these bands are highly mineralized.On the contrary,the correlation of these elements is very low in the non-mineralized bands.The correlation analysis indicates that Bi and Ag could act as the indicators for deep gold geochemical exploration.As a result,the prospecting target should lie in the head of concealed ore zones and there is a large potential for gold prospecting in the depth.

Key words: Drill core geochemical exploration, Shuijingtun gold deposit, Correlation analysis, Hierachical Cluster Analysis
