本文阐明了激电二次场和视极化率异常与矿体产状和导电因子的作用规律。给出几种常见规则几何形体上激电二次场和视极化率异常与矿体产状和导电因子作用规律的数量关系,并获得了一些重要结论:即在电子导体体积含量一定的体积极化条件下,矿体的电化学激电异常值是受极化体导电因子(μ)的饱和效应控制的。在矿体产状、大小和埋深均为一定的条件下,激电异常剖面曲线形状和特征,随矿体导电因子量值的大小而发生相应的明显变化。这些规律对实际找矿工作十分重要。
This paper clarifies the law of the secondary field and apparent polarizability of anodes and the shape and conductivity of ore bodies. The relationship between the second order field and the apparent polarizability anomalies and the regularity of the orebodies’ shape and conductivity factors on several common regular geometries is given, and some important conclusions are obtained. That is to say, when the volume of the electronic conductor is constant Under the condition of polarization, the abnormal values of electrochemical polarization of the ore body are controlled by the saturation effect of the conductivity factor (μ) of the polarizer. Under the condition of the ore body’s shape, size and depth, the shape and characteristics of the curve of the anomalous section of the anomaly change correspondingly with the magnitude of the conductivity factor of the ore body. These laws are very important for the actual prospecting work.
