摘　　要：特征分析法在矿产预测中有着极为广泛的应用;在研究当曲式铁矿矿床地质特征、成矿规律的基础上,将特征分析方法应用到最小预测区优选中。根据成矿模型优选出含矿建造、断裂构造、航磁异常等8个预测变量,在12个最小预测区中圈定出了7个一级最小预测区和4个二级最小预测区,指出了进一步找矿方向。Characteristic Analysis is used widely in the optimization of prospective area of mineral deposits. Based on summing-up geological characteristics ore-forming disciplinarian and ore-prospecting indicators in the Dangqu steatabound- type iron deposit area, the characteristic analysis is applied to prospective area of mineral deposits. According to this model, 8 prediction variahles containing stratum , structure , geophysical , geochemical , remote variables are chosen. 7 fixst-order prediction target areas and 4 second-order areas are recognized in this study. Further ore-prospecting direction is given. The quantitative prediction method ore-prospecting targets is researched. Better ore-prospecting effect is made.
