摘　　要：通过对地电化学找矿法研究现状的分析,基于金属矿床地电化学成晕机制的新认识,提出了用于地质勘查的地电化学改进方法,克服了以往CHIM方法设备笨重,操作不方便,提取液容易渗漏,工作效率低等缺点。该方法在广西南乡泰富金矿进行了试验研究,在已知金矿体上方和构造破碎带上方均有Au地电化学高值异常出现,在厚层覆盖地段进行了找矿预测,部分地段通过探矿工程揭露,找到了金矿体,证实了改进的地电化学方法的可行性和有效性。Through the analysis of the present situation for geoelectrical chemistry prospecting, the improved methods and techniques of geoelectrical chemistry were presented on the basis of new standpoints of geoelectrical chemistry halo-forming mechanism for metallic deposits, which overcame previous heavy equipment, inconvenient to operation in the field, leakage for electrolyte solution, inefficient, etc. The methods and techniques were tested and studied on Taifu gold deposit in Nanxiang of Guangxi, and the results have showed that Au geoelectrical chemical anomalies appeared over known gold ore bodies were discovered in parts of the area by means of prospecting engineering exposing. These verified that improved methods and techniques of geoelectrical chemistry were feasible and available.
