激发极化法在桃坪山铅锌矿区的应用效果

桃坪山铅锌矿区的激电异常反映好且范围大,并有一定的规律,以地质特征与物性特征为前提,通过对构造带及探槽、钻孔工程揭露的矿(化)体部位的激电异常特征的分析,认为该区低阻高极化的激电异常是一个有效的找矿标志,提出继续增加激电工作和对部分激电异常进行工程验证的建议。

Application of the Polarization Method on the Taopingshan Lead-zinc Ores Mining

The induced polargation anomaly in the Taopingshan lead-zinc ores mining is better for reflection and larger in range,which has some regular rules.Based on analysis results of induced polargation anomaly in the structural zones and the mineralizing part exposed by exploratory trenches and drill wells,it is considered that the induced polargation anomaly with low resistivity and high polarization in the surveyed area is an effective ore-hunting indicator.In the paper it also offers some proposals for continuing the induced polargation tasks and carrying out an engineering verification in some induced polargation anomaly.
