激发极化法在华东某金矿勘探中的应用

本文根据矿体和围岩之间极化率和电阻率的差异进行地质勘探的原理,充分研究华东某工作区的地质、地球物理特征,针对该工区硫化物矿化带和矿化富集地段间矿体和围岩之间极化率和电阻率差异较大的情况,进行了大功率激发极化法中梯装置和激发极化测深测量,并对扫面和测深的成果进行分析,结合地质资料预测了寻找金矿的理想位置,取得了对该金属矿类勘探的经验、认识和效果,为下一步钻探或深入开展地质找矿工作提供了有利的依据。

Application of Induced Polarization Method in a Gold Mine Exploration of Eastern China

This paper, based on the principle of geological exploration according to the difference between polarization and resistivity of ore body and surrounding rock, fully studies the geological and geophysical characteristics in the work place of eastern China. In view of the situation of large difference between polarization and resistivity of ore body and surrounding rocks in the sulfide mineralization zone and mineralization area, the high-power excitation polarization gradient device and induced polarization sounding inspections are carried out. This paper analyzes the sweeping surface and sounding results, and predicts the ideal location of the gold mine area combining with the geological material, with the metal ore exploration experience, knowledge and results got, which provides a favorable basis for further drilling or deeply developing geological prospecting work.
