早子沟金矿位于西秦岭西段，大地构造位置为西秦岭褶皱带北部断褶带与中部裂陷槽之间的过渡部位，位于合作-岷县区域断裂带上。对矿区原生晕样品元素分析得到的数据进行R型聚类谱系分析、因子分析及元素分带指数计算。聚类谱系分析反映出矿化元素Au、Sb与前缘晕元素As、Hg关系密切；因子分析显示第一主因子与第四主因子具有正相关关系，而与二、三主因子无相关性，说明四个因子代表了三个不同的成矿阶段；依据元素分带指数计算建立的矿区原生叠加晕轴向（垂直）分带序列为As-Au-Sb-Hg-Ag-W-Co-Pb-Zn-Bi-Cu。对矿区原生晕找矿地球化学信息进行了提取，并对矿区深部第二富集带靶区及资源量进行了预测，预测资源量5 t，表明矿区深部扩大资源量的潜力巨大。

The Zaozigou gold deposit is located in the western segment of West Qinling Mountains. The authors conducted R type clus-ter 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 pri-mary 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.
