有人曾经提出,进入矿化期后的岩石中的以及进入覆在硫化矿矿床上面搬运来的覆盖层中的元素次生晕,可能部分是由于与自然电流有关的电化学机理所引起的。如果这种次生晕是一种持续的作用,那么在硫化矿矿体周围电场带内,相对来讲,可溶于水的离子的浓度比例应该有很大的变化。确定这种浓变的简单方法是测量含水粘土泥样品的电导率;在某硫化矿矿床的一条剖面上测量土壤粘土泥的电导率的结果,发现有明显的电导率异常。后来在实验室的试验槽内进行了研究,结果证明,在硫化矿矿体周围产生的电位和在周围脉石矿物中的元素次生晕之间,有一个经验关系(由于电化学反应的结果,在硫
It has been suggested that the secondary halo of elements entering the rock after mineralization and into the cover that is carried over the sulphide ore deposits may be due in part to the electrochemical mechanism associated with the natural current. If this secondary halo is a continuous function, then the relative concentration of water-soluble ions in the electric field around the sulfide ore body should vary considerably. A simple way to determine this concentration change is to measure the electrical conductivity of samples of clay containing water; as a result of measuring the conductivity of soil clay mud over a section of a sulphide ore deposit, significant conductivity anomalies were found. A subsequent study in a laboratory test cell showed that there was an empirical relationship between the potential generated around sulfide ores and the elemental secondary halo in the surrounding gangue minerals (as a result of the electrochemical reaction , In sulfur
