| 摘 要： | 在总结前人资料的基础上，根据最新的研究成果，以Au为例提出了地电提取异常的形成模式。地下深处的隐伏矿体发生电化学溶解，在多种地质营力作用下，使呈阳离子和阴离子态的金属离子迁移至近地表松散层中，在表生介质中吸附而富集。利用人工电场将土壤中呈活动态的金属离子提取沉积在电极上，这部分离子晕称为地电提取离子异常。地电提取离子晕是活动态的，与下伏矿体有着动态联系，离子晕的成分与隐伏矿体的物质组分相一致，与隐伏矿床在地表的垂直投影相吻合，对寻找深部的隐伏矿床有重要的指示意义。

| Abstract: | Based on the latest research results,an Au halo CHIM pattern is proposed on the basis of known data summarizing.Electrogeochemical dissolving is happened in concealed deposits.Metallic anions and cations are migrated to the earth surface by all kinds of geological force and enriched in supergene zones.It is called halo CHIM that electromobile metal ions are extracted by either anodes or cathodes in a artificial electric field.CHIM ionic halo,which is dynamic related to the concealed deposit,is in mobile form.The elemental composition of the halo normally is the same with that of ores,and the halo occurs typically directly above the source of deposit.Therefore,CHIM ionic halo has significant applications on finding concealed deposit. |
