摘要
复电阻率法是以岩矿石的频谱或时谱特性差异为研究基础,本文简要介绍了复电阻率法的基本原理和本方法可以通过柯尔—柯尔模型计算得出的几个视谱参数及其意义。然后介绍了复电阻率法在安徽某铜钼矿勘查中的具体应用,并以其中一条工作剖面为例,简要介绍了本次工作所取得的一些成果,并且在后期的钻井工作中验证了此次复电阻率法工作中推测的一些地质体、地质构造的位置、深度信息是较为准确的。由此得出在地质找矿工作中综合考虑与岩矿石极化物质成分和结构有关的时间常数和频率相关系数等多个视谱参数,可以减少多解性,提高地质解释水平和工程验证见矿率。
Complex resistivity method is based on spectral properties differences of rocks and minerals. This paper briefly introduces the basic principle of complex resistivity method and several visual spectrum parameters and their significance of this method that can be calculated by colecole model. This paper also introduces a specific application of Complex resistivity method in An Hui copper molybdenum mine exploration. Taking one cross- section for example, this paper briefly describes some results obtained in the work. In later drilling, some geological bodies, the location of the geological structure and its depth deduced by this method are verified. Therefore, it is necessary in mine prospecting to consider the time and frequency multiple parameters which are related to the composition and structure of rock and minerals, since it can reduce the varieties, improve the geological explanation and mine exploration.
