| 摘 要： | 隐伏金矿地电化学异常的形成主要是由于在多金属硫化物矿床内部不同矿物组成的微观原电池作用下，矿体产生电化学溶解，导致矿体周围形成金的离子晕；这些金离子晕在地电场、浓差扩散、地下水循环等因素作用下，向地表迁移形成了地电化学金异常。在地表测出的地电化学金异常又因矿体的埋深和产状不同表现出不同的形态特征。

| Abstract: | The geoelectric anomaly is resulted from the ionic halo of Au around the ore bodies, through electrochemical dissolution effected by micro cells composed of different minerals. By function of geoelectric field, concentration diffusion and circulating ground water, the ionic halo of Au is transported upward to surface and forms a specific geoelectric anomaly of Au, which represents diverse patterns because of varied occurrences and different depth of the concealed orebodies. |
