一种激电异常圈定方法研究——以承德某矿区为例

Study on a method of IP anomaly delineation--Taking a mining area in Chengde as an example

电法勘探技术在我国有色金属勘探、寻找地下水等领域得到了广泛的应用。激电异常主要通过分析视电阻率、视极化率特征,寻找地下隐伏金属矿床。目前的异常圈定方法主要是基于数据统计方法来确定异常下限来圈定激电异常。为了达到更好的了解地下隐伏地质体电性特征的目的,本文在结合视极化率及视电阻率的综合特征分析的基础上,做了重新圈定激电异常的一种方法研究。

Electrical exploration technology has been widely used in nonferrous metal exploration and groundwater search.By analyzing the characteristics of apparent resistivity and apparent polarizability,IP anomalies are mainly used to find buried metal deposits.The current abnormal delineation method is mainly based on the data statistics method to determine the abnormal lower limit to delineate IP anomalies.In order to get a better understanding of the electrical characteristics of underground concealed geological bodies,based on the analysis of the comprehensive characteristics of the visual polarization rate and the apparent resistivity,a new method for the delineation of IP anomalies is presented in this paper.
