| 摘 要： | 工作区地处西伯利亚与哈萨克斯坦一准噶尔这两大板块之接合部位的陆缘裂谷带附近，重要有色金属矿床多分布于额尔齐斯深大断裂两侧，有很好的成矿前景。采用激发极化法圈定激电异常区，在异常评价中，用提取激电二次信息的视金属因素（以）法，突出低阻极化体异常，压制高阻极化体异常，强化矿致异常，压制非矿致异常干扰，成功区分矿与非矿异常。通过求取视金属因素，圈定了重点勘查区域，并在重点勘查区域布置测深剖面，指导了钻孔的布置。钻探见矿验证了激电法在该区应用效果良好。

| Abstract: | This paper deals with the effect of applying the metallic factor to the interpretation of IP anomalies in an ore district of Fuyan County, Xinjiang. Induced polarization method of geophysical electrical survey was employed to select electricity unusual areas, with the purpose of identifying the IP anomalies in the work area. The authors used the method of apparent metallic factor （ Js ） by extracting IP secondary information to make prominent the low resistivity polarization anomalies and suppress the high resistivity polarization anom- alies, thus strengthening the ore-related anomaly, suppressing the interference of barren anomalies, and successfully distinguishing ore- related anomalies from barren anomalies. Through calculating the dependency on the apparent metallic factors, the authors delineated the key exploration areas, and arranged IP sounding profiles in key exploration areas, thus guiding the drilling work. The drilling re- sults has proved the effectiveness of the IP method in the exploration work of this area. |
