Abstract：The Zaozigou gold deposit is located in the western segment of West Qinling Mountains. The authors conducted R type cluster and lineage analysis, factor analysis and element zoning index calculation for data obtained by the analysis of primary halo samples from the ore district. The cluster and lineage analysis shows that there exists close relationship between mineralization elements Au, Sb and front halo elements As, Hg. The factor analysis reveals that the first principal factor is positively correlated to the fourth factor but has no correlation with the second and third factor, suggesting that the four factors represent three different ore-forming stages. The primary superimposed halo axial (vertical) zoning sequence of the ore district based on element zoning index is As-Au-Sb-Hg-Ag-W-Co-Pb-Zn-Bi-Cu. The authors extracted primary halo prospecting geochemical information from the ore district and predict the deep second enrichment zone target and its resource quantity. The predicted source quantity is 5 t, suggesting considerable potential for expanding resource quantity in the depth of the ore district.
