自然电场法的许多找矿实例业已证实:金、铜、铁、铅锌等金属硫化矿体均可能产生正负伴生的自电异常.例如,璜山金矿、玉龙铜钼矿、力马河铜镍矿、西迹山黄铁矿、南江黄铁矿、拉祖尔斯铅锌矿等. 这种正负伴生的自电异常早就引起了人们的注意.苏联??认为正异常的产生是矿体下盘氧化所致,??等人则把正异常的出现与矿体中部所进行的氧化过程状态相联系,??认为正异常的形成与矿体成分有关,铅锌矿可以产生正异常,而含铁的(黄铁矿、黄铜矿)只可能产生负异常.上述这些假说颇难圆满地解释实践中观测到的各种正负伴生的自电异常. 勿容怀疑,在一定的地质条件下,金属矿能
Many natural mineral prospecting methods have confirmed that gold, copper, iron, lead and zinc and other metal sulfide ore bodies may have positive and negative associated with the self-anomalies, for example, Huangshan Gold Mine, Yulong copper and molybdenum ore, Lima River Copper and nickel ore, Xishan Mountain pyrite, Nanjiang pyrite, Lazers lead-zinc mine, etc. This kind of positive and negative associated with the self-anomalies already attracted the attention of the Soviet Union that the occurrence of positive anomalies Is due to the ore body under the plate caused by oxidation, etc. who is the occurrence of positive anomalies and the central part of the ore body oxidation process linked to that the formation of positive anomalies and ore body composition, lead and zinc can produce Positive anomalies, and ferrous (pyrite, chalcopyrite) may only produce negative anomalies. These hypotheses are difficult to satisfactorily explain the practice observed in a variety of positive and negative accompanied by self-anomalies. Do not doubt that in Under certain geological conditions, metal ore can
