摘　　要：为解决内蒙古格鲁其堆山矿区外围区找矿问题,笔者本着"由已知向未知"的研究思路,在格鲁其堆山矿区开展地电化学集成技术找矿应用。选取矿区内已知剖面进行试验研究,结果显示:在已知矿体上方均显示出了明显的Cu、Pb、Zn等元素异常,验证地电化学集成技术在该地区寻找隐伏铅锌矿产是可行的。再在矿区西南部的未知区内开展隐伏矿预测研究,运用因子分析得出矿区最佳找矿元素组合,结合单元素异常图和成矿地质条件,在研究区内圈定1个Ⅰ类靶区、1个Ⅱ类靶区和1个Ⅲ类靶区。This work focused on search for hidden ore bodies in the Geluqiduishan mining area in Erguna City of Inner Mongolia.Following the thought line“from known to unknown”,we applied the geo-electrohemical integrated technology to this area.Known profiles in the mining area were chosen for experiments using this approach.Results show that there are obvious elemental anomalies such as Cu,Pb and Zn above the known ore bodies.It is verified that the geoelectric-chemical integrated technology can be successfully used in this area to search for hidden lead-zinc deposits.Then,the prediction of concealed ores was made in the unknown area in the southwestern mining area,and the best ore-prospecting element combination was obtained by factor analysis.Combining with the single element anomaly map and metallogenic geological conditions,we have determined a classⅠ,a classⅡand a classⅢtarget in the study area,respectively.
