| 中文摘要: |
| 上宫金矿属于构造蚀变岩型金矿,成矿部位与断裂、破碎带分布密切相关。断裂附近岩体破碎并矿化后其电阻率值较围岩有明显降低,根据这一电性差异,文章以河南省上宫金矿为例,利用可控源音频大地电磁法(CSAMT)查找破碎带,并结合已知地质情况分析研究,合理布置钻孔位置,成功揭露物探推断异常,达到找矿目的。 |
| 英文摘要: |
| The Shanggong gold deposit is structure-controlled alteration type gold deposit. The mineralization position is closely associated with the distribution of faults and fractured zones. Based on the variation of the resistivity of the fractured and mineralized rock and the intact rock, CSAMT method is applied to detect the distribution of the fracture zone in the case study of Shanggong gold deposit. The test drillings is arranged to confirm the geophysical anomaly in consideration of geological conditions. Finally the orebody was found and the prospecting purpose is realized. |
