摘　　要：作者利用特征分析法对广西南丹芒场锡—多金属矿田隐伏矿床(体)进行了定量预测。通过选择21个地质、物化探变量,建立了矿田内成矿预测模型,并计算了预测区内各单元的成矿有利度,指出了矿田内成矿预测远景区,部分成矿远景区已为勘探所证实。Author used the characteristic analysis method and made a quantitative prediction of the hiden ore deposits (bodies)in Mangchang tin-polymetallic Ore Field,Nandan District,Guangxi.And by selecting 21 variables(include the geological,geophysical and geochemical),ore-forming predictive model was set up.Then the author calculated ore forming favorable degree of all units in predictive area,and pointed out ore forming prospective areas in ore field,some of them were verified by exploration.
