【摘要】 作为豫西重要的金多金属矿床之一，申家窑矿床勘查工作多集中于500 m以浅，深部工作程度相对较低。为探求豫西申家窑金矿床深部找矿潜力，本文采用钻孔岩石地球化学测量的方法，使用格里戈良法确定原生晕轴向分带序列，分析研究了矿床原生晕轴向分带特征，获得的结果有：主矿体崤09原生晕轴向分带序列为As-Ag-Cu-Sn-Mo-Bi-Sb-Pb-AuZn-W，具反向分带序列的特征；Au、Zn、Ag、Pb、Cu为近矿指示元素，As、Sb、Mo为前缘晕元素，Bi、W为尾晕元素，表现为前缘晕元素随深度的增加逐渐减小，尾晕元素逐渐增大；原生晕轴向叠加特征在+680～+620 m处呈现了高峰值，为矿体主要赋存标高，至+500 m处则重新出现增高的趋势，预测深部可能有盲矿体存在，大致为03线上主矿体西南方向的延伸，预计新增金资源量1000 kg。研究成果可为申家窑金矿床进一步寻找深部矿体提供地球化学依据。更多还原

【Abstract】 As one of the important gold polymetallic deposits in western Henan, the exploration work of the Shenjiayao deposit is mostly concentrated at depths above 500 meters, and the degree of deep work is relatively lower. In order to explore the deep prospecting potential of the Shenjiayao gold deposit in Xiaoshan, western Henan, using the drilling rock geochemical survey, this paper gets the primary halos axial zoning sequence, analysis the anomaly concentration distribution characteristics of the metallogenic elements, studies the axial zoning characteristics of primary halos, probes into the geological significance of primary halo zoning characteristic, and has carried out deep prospecting prediction. The results obtained are as follows:(1) The axial zoning sequence of the primary halo of the main ore body Xiao-09 is As-Ag-Cu-Sn-Mo-Bi-Sb-Pb-au-Zn-W, which shows the characteristics of reverse zoning sequence;(2) Au, Zn, Ag, Pb, Cu are near-ore indicator elements, As, Sb, Mo are front halo indicator elements, Bi, W are tail halo characteristic indicator elements, and with the increase of depth, the anomalies of front halo elements gradually decrease and tail halo elements gradually increase;(3)The axial superposition characteristics of the primary halo showed that the axial coefficient peak value appeared at the site of +680-+620 m, indicating the main occurrence elevation of ore bodies, and at the site of +500 m the ore body showed an upward trend indicating that there may be ore bodies in the depth, which is speculated to be the southwest extension of the ore body of 03 line, and 1000 kg additional gold resource. So this study expands the ore prospecting prospect and provides geochemical basis for further exploration of deep orebodies in Shenjiayao gold deposit.更多还原
