| 摘 要： | 为了在安徽省巢湖市山里许以西实现新的找矿突破,先后投入了双频激电扫面工作及大功率激电测深剖面工作。通过对取得的激电异常特征进行研究,推断了2处构造的分布; 提取激电二次信息发现,激电电导率异常在研究区已知铜矿化部位有较好的反映,综合激电异常等特征,圈定了研究区以西2处成矿靶区; 通过激电多参数与已知矿体综合分析,能有效地评价研究区矿致异常,为下一步钻探工程验证提供地球物理依据,也为今后在类似矿区外围找铜金多金属矿的地质工作者提供参考。

| Abstract: | In order to achieve a new prospecting breakthrough in west of Shanlixu area, the authors have conducted the dual frequency IP scanning and high-power IP sounding profile work. The distribution of two structures was inferred through the study of the characteristics of IP anomalies. The IP conductivity anomalies were well reflected in the known copper mineralization position in the study area after the extraction of the secondary information of IP, and two metallogenic targets in the west of the study area were delineated according to this anomaly characteristics combined with the IP anomaly characteristics. These results show that the ore-induced anomalies in the study area could be effectively evaluated by the comprehensive analysis of IP multi-parameters and known ore bodies, which could provide the geophysical basis for the next drilling engineering verification and help geologists find copper-gold polymetallic ores in the periphery of similar mining areas. |
