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.
