电吸附化探新方法在麻湾金矿区寻找深部矿体的研究

Application of Electro-sorption Geochemical Exploration in Deep Orebody Prediction in Mawan Gold Mining Areas

介绍了电吸附找矿方法的异常形成原理及其应用现状,将电吸附找矿方法应用于麻湾金矿区的电吸附异常研究,在工作区内获得了多个异常,异常高叠合度主要集中在测区的中南部,各元素吻合很好。为了验证异常,在工作区布设了3个钻孔,均见到明显的金矿体,最深处>1 000 m。异常结果与钻探结果的对比分析表明,电吸附找矿法的异常能反映出深部隐伏矿体,而常规化探方法只能反映出地表出露的矿体,表明了电吸附方法寻找隐伏矿的效果优于常规化探方法。

This paper introduce the principle of the electro-adsorption prospecting method and its application sta- tus.By using the electro-adsorption prospecting method,several anomalies were found in Mawan gold mining areas, high stackheterozygosity anomalies are mainly concentrated in south-central of the areas,all elements are in good a- greement.In order to verify abnormal,three holes are laid in the work area,in which gold orebody are obvious,with maximum depth more than 1 000 re.Comparative study between the abnormal results and drilling results show that the anomalies of electro-adsorption prospecting method can reflect the deep buried ore bodies better than conven- tional geochemical methods,which can only reflect the outcropping ore body,indicating that the electrosorption method are more effective in searching for buried ore prospecting than conventional geochemical methods.
