摘要: 为了获得北衙超大型金多金属矿床外围找矿工作的突破，本文在已知典型矿床模型上，开展直流激电与双频激电方法的对比试验研究。结果表明，两种方法都能有效揭示已知矿体的分布，但直流激电具有更强的抗干扰能力和更高的深部分辨率，所以直流激电方法可能更为适合北衙矿区。土壤化探资料揭示北衙远景区I土壤里高丰度的铅锌含量对激电异常具有较大干扰。利用直流激电与土壤化探的方法组合，揭示了北衙远景区II矿体的分布范围，取得了良好的应用效果，为北衙外围找矿提出了有效的技术方法组合建议。Abstract: In order to make a prospecting breakthrough in the peripheral areas of Beiya, a super large gold polymetallic deposit in the northwest of Yunnan, this paper carries out a comparative experimental study of IP and dual-frequency IP methods in the known typical orebodies. The results show that both methods can effectively reveal the distribution of known ore bodies, but IP has a stronger anti-interference ability and a higher deep resolution, so IP is more suitable for Beiya area. Soil’s geochemical data reveal that the high abundance of Pb and Zn in the soil of Beiya prospective area I has great interference on IP anomalies. The distribution range of orebody II in Beiya prospect area is revealed by using the combination of IP and soil’s geochemical method, which has achieved good application effect and provided an effective technical method combination for the exploration of the peripheral area of Beiya in the future.
