| 中文摘要: |
| 文章通过对金蟾山金矿矿区地球化学原生晕的统计分析、微量元素异常等值线图分析、不同类型岩石统计及微量元素特征分析,认为矿区各微量元素均满足正态分布,最佳微量元素指示元素为Au,Cu,Hg,Bi;重要微量元素指示元素为Pb,Ag,As;Zn,W,Mo,Mn也可起到一定的指示作用;金矿脉的综合轴向分带序列为:Mo-Cu-Au-As-Mn-Bi-Ag-W-Hg-Zn-Pb-Sb,因而矿区深部头晕元素位于尾部,而尾晕元素位于头晕,Hg与Pb,Zn等成矿元素产出靠近尾晕,所以深部多个平行盲矿体存在可能性较大,向下具延深趋势,且深度较大. |

| Statistic analysis of primary geochemical halo anomaly of Jizhanshan gold mining area,analysis of anomaly contour of micro-element,statistic analysis of different rocks and analysis of micro-element characteristics show that each micro-element in the mining area are in normal distribution,Au,Cu,Hg,Bi the optimum indicators,Pb,Ag,As;Zn,W,Mo,key indicators,Mn the indicator sometimes;element zonation along axis of gold vein in order of Mo-Cu-Au-As-Mn-Bi-Ag-W-Hg-Zn-Pb-Sb.Accordingly,the authors conclude that elements of the front halo occur at the rear halo and vice versa.Hg and Pb,Zn,the ore element occur near the rear halo.Therefore,it is possible that blind ore bodies occur parallel at depth and tend to extend to further depth. |
