摘要:
在狮子山矿田胡村深部铜钼矿开展了地电化学方法技术找矿可行性研究。试验结果表明,地电化学测量可以提高异常衬度,特别适合对弱异常区进行地球化学详查工作;As、Sb、Se、Ag、Pb衬度高,异常范围宽,具有一定的深部找矿意义;Ba、Zn也具有一定的指示意义。此外,利用常规电化学测量获得的pH值和电导率异常,能有效区分出浅部矿化导致的地电提取异常。根据野外试验,该方法不适合土层较薄的基岩出露区。同时,考虑到工作量较大,认为地电化学测量可以用于精细地球化学深部找矿工作。
Abstract:
The feasibility study of the geoelectric extraction method was conducted in the Hucun copper deposit, Anhui Province. The result shows that the geoelectro-chemical extraction method can improve anomaly contrast and hence is very suitable for detailed explo?ration work of weak regional geochemical anomalies. In particular, As, Sb, Se, Ag and Pb with a high anomaly contrast and a wide ab?normal range are somewhat valuable for deep mineral exploration. Ba and Zn also have some indication significance. In addition, the au?thors measured the pH andκs anomalies which could effectively distinguish geoelectric extraction anomalies caused by shallow minerali?zation. According to the field test, the method is not suitable for thin soil bedrock outcrop area. At the same time, taking into account the considerable workload, the authors hold that the electrochemical measurements can be used to fine deep geochemical prospecting work.
