云南大红山铜铁矿床为一赋存于古元古代大红山群火山沉积地层的超大型矿床．为加深已知典型矿床的研究程度，并有效地指导新区的找矿工作，在系统的原生晕采样基础上，通过不同的方法建立了多种形式的地球化学找矿模型：地球化学背景与异常的概率筛分模型、因子分析及元素组合模型、最优分割法及水平分带模型、标准化丰度法及轴向分带模型，以及多标高联合曲线法及主矿元素Ｃｕ的立体变化模型等．用上述模型，配合地质物探综合研究，在实践中已取得显著找矿效果． The Dahongshan copper-iron deposit in Yunnan Province is a super-large deposit hosted in volcanic sedimentary formation of the Paleoproterozoic Dahongshan Group. In order to deepen the research on the known typical deposits and effectively guide the prospecting work in the new area, various forms of geochemical prospecting models have been established by different methods based on the systematic primary halo sampling: geochemical background and anomalies The probability analysis, the element combination model, the optimal segmentation method and the horizontal zoning model, the standardized abundance method and the axial zonation model, the multi-elevation joint curve method and the three-dimensional change model of the main mineral element Cu . With the above model, with geophysical geophysical research, in practice has made significant prospecting results.
