| 中文摘要: |
| 枪马金矿区位于小秦岭金矿带，该带是我国三大原生金矿成矿区之一。通过剖析元素地球化学数据统计特征，综合应用数学地质多元统计分析、元素原生晕地球化学特征及原生晕轴向分带序列等地球化学数据研究方法认为：60-1脉最佳矿化指示元素为Au，重要找矿指示元素组合为Cu-Pb-Ag-Bi-Hg；60-1脉单矿体原生晕轴向分带序列为Sb-Hg-As→Cu-Ag-Bi-Au-Pb-Zn→Mn-W-Mo；60-1脉为多矿体综合叠加构成并建立了60-1脉原生晕叠加理想模型。 |
| 英文摘要: |
| Qiangma Au deposit is located at Xiaoqinling Au ore belt which is one of the big Au ore belt in China. The paper analyzes the statistical characteristics of elemental geochemical data and synthetically utilizes geomathmetical statistical methods, such as multi-element statistics, characteristics of elemental geochemical primary halo, axial zoning of the primary halo etc. Procession of the data results in the conclusion: Au is the optimum indicator and Cu,Pb,Ag,Bi,Hg the important elemental combination indicator of mineralization of ore vein 60-1; sequence of the axial zoning of the vein is Sb-Hg-As→Cu-Ag-Bi-Au-Pb-Zn→Mn-W-Mo and the vein is the result of multi-ore body overprinting. On basis of analysis of the data ideal primary overprinting model of the vein is built and the model is of a certain significance to further Au ore exploration in the area. |
