在详实的地质工作基础上,笔者在怕拍铜矿地区开展了1:2000大比例尺岩石地球化学找矿工作.选用迭代法确定背景值和异常下限,确定Cu、Pb、Zn、Ag、Hg等五个元素组合作为本次研究的最佳指示元素.通过分析岩石地球化学异常形态、规模、浓度分带等,在该矿区圈定找矿靶区4处,为寻找盲矿体,缩小靶区提供依据.%Based on the geological work, we did the prospecting work with the lithogeochemical method in PAPAI copper ore area. The iteration method was adopted to determine the background value and anomaly threshold, with the assemblage of Cu, Pb, Zn, Ag, and Hg as the best indicator. By analyzing the geochemical anomaly shapes, scale and concentration zonation, 4 prospecting targets were determined, which will provide basis for the searching of blind orebodies in the area.
