摘要:

在广西融水县有富多金属矿区开展3种地球化学方法(地电提取测量法、土壤离子电导率测量法和土壤热释汞测量法)的测量找矿研究工作。在一含铜矿化脉体上方发现有电导率(Con)、热释汞(Hg),地电提取Au离子的异常,认为地电化学方法在该区是可行和有效的。运用这套方法在研究区发现了5个电导率异常、10个土壤热释汞异常、13个地电提取Au异常,从而圈定出有望找矿(化)综合异常(段)6个,并划定出2块异常找矿远景区。由于研究区为未知地块,因此建议施工7个地表探槽,探槽总长230m。

Abstract:

Three kinds of geochemical methods (partial extraction of metal, soil ionic conductivity measure and soil mercury absorbed measure) were performed to prospecting in Youfu polymetallic mine in Rongshui County of Guangxi. Above a copper-mineralized vein, there were conductivity ionic anomalies, oil mercury absorbed anomalies, geoelectro-tracted gold ionic anomalies, suggesting that the electrochemical methods were feasible and effective in the area. Using these methods, 5 conductivity ionic anomalies, 10 soil mercury absorbed anomalies, and 13 geoelectro-extracted gold ionic anomalies were found in the study area. Six expected prospecting (mineralization) integrated anomalies (abnormal sites) and 2 prospect areas of anomalies were delineated. As the working area is an unknown land, seven tanks of surface exploration are proposed to be constructed, with a total length of 230 meters.
