中文摘要:
      河南郭家岭金矿床位于华北陆块南缘褶皱带多金属成矿带与北秦岭多金属成矿带交界处。文章结合矿区地质背景、矿床成因、矿体特征及钻孔岩石地球化学采样分析,系统地研究了矿床深部的原生晕地球化学特征。地球化学原生晕统计分析表明,郭家岭金矿区矿化普遍高于区域背景值,Au、Ag、Cu、Mo、Sn、W、Zn、Sb、Bi 9种元素的富集系数较大。通过R型聚类分析,表明钻孔内元素间相关性较好,与Au相关性最强的元素为Bi,并且As、Sb、Zn元素组合异常强烈,而W、Mo元素组合异常较弱,表明该金矿床属于高温热液矿床,处在原生晕的前缘;从钻孔原生晕空间分布看,原生晕异常现象明显,矿化较好,与Ag、Cu、Pb元素有较强的相关性,表明该金矿床处在异常前缘或者异常中上部。
英文摘要:
      The Guojialing gold deposit is located in Lushi County, Henan Province, at the junction of the polymetallic metallogenic belt of the fold belt in the southern margin of the North China block and the North Qinling polymetallic metallogenic belt. In order to explore the deep metallogenic potential of the Guojialing gold deposit, this paper systematically studied the geochemical characteristics of the primary halo in the deep part of the deposit based on the geological background of the mine, the genesis of the deposit, the characteristics of the ore body and the geochemical sampling analysis of the borehole. The statistical analysis of the primary faint halo of geochemistry shows that the mineralization of the Guojialing gold deposit is generally higher than the regional background value, and the enrichment factors of the nine elements of Au, Ag, Cu, Mo, Sn, W, Zn, Sb and Bi are larger. The R-type clustering analysis shows that the correlation between the elements in the borehole is good, and the element with the strongest correlation with Au is Bi, and the combination of As, Sb and Zn is unusually strong, while the combination of W and Mo elements is weak. It indicates that the gold deposit belongs to a high temperature hydrothermal deposit and is at the leading edge of the primary halo; From the spatial distribution of borehole primary halo, the primary halo anomaly is obvious, the mineralization is better, and there is a strong correlation with Ag, Cu and Pb elements, indicating that the gold deposit is at the abnormal front or the upper middle part.
