摘要
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 super-larged Cu-Fe deposit in Yunnan Province occurred in volcano-sedimentary strata of Danhongshan Group of Paleoproterozoic era. To deepen the study of known typical deposit and effectively guide ore-finding, based on systematic sampling and quantitative analysis, various geochemical ore-finding models with different data processing methods are established. They are: the probability sieve model of geochemical background and anomaly, the factor analysis and elements assembling model, the multielement optimization dividing and horizontal zoning model, the standardization abundance method and axial zoning model, and the multilevel united curves method and tridimensional variation model.
