摘要
当激电异常较为复杂时,利用ηs(或Fs)这些激电法的基本参数难以对异常源的性质进行合理的解释。通过具体实例,说明应用激电法的二次信息———金属因素解释复杂激电异常的有效性。金属因素能将矿致异常与非矿致异常分离,对异常的定性及定量解释有很好的作用。
When an IP anomaly is relatively complex, the application of such basic parameters as ,ηs and Fs can hardly make reasonable interpretation of the nature of the anomaly source. With practical examples, the authors point out the effectiveness of applying the second information of IP, i.e., the metallic factor, to the interpretation of complex IP anomalies. The metallic factor can separate ore-related anomalies from barren ones, thus playing an effective role in the qualitative and quantitative appraisal of the anomaly.
