差异激电法探查地下水及区分矿种的初步研究

本文提出激发极化差异效应和激电差的概念并给出定义,首次使用“差异激电法”这一述语。通过在平原和山区的贫水及富水区的应用以及室内金属板、石墨板和金属矿物、炭质岩石标本的水槽模拟实验,说明基于激发极化差异效应的差异激电法在探查地下水以及找矿、区分矿种方面的有效性,初步探索了异常反映规律。

A PRELIMINARY STUDY ON THE APPLICATION OF THEDIFFERENTIAL INDUCED POLARIZATION METHOD TOTHE DETECTION OF GROUNDWATER AND THEDISTINCTION BETWEEN ORE SPECIES

Abstract This paper advances the concepts of induced polarization differential effect and IP difference and gives them definitions. It is for the first time that the term differential IP method is used. The application of this method to water-poor and water-rich areas in plains or mountain regions and the in-house water trough simulation experiments on metallic plates, graphite plates and specimens of metallic minerals and carbonaceous rocks prove the effective-ness of the differential IP method based on the induced polarization differential effect in groundwater exploration and ore prospecting as well as in the distinction between ore species. A preliminary discussion is also made on the regularity of anomaly reflection. The method is simple and can distinctly reflect anomalies; hence it might be used in productive activities.
