摘　　要：在皇城山银矿成矿带原生晕找盲矿专题研究中,采用相似性判别分析,建立判别指数,结合元素对比值等指标对A1岩脉各段进行相似性判别分析,收到了较好的预测效果。为矿区的全面评价、缩小找矿范围、加快矿区勘探提供了地球化学依据。结合原生晕找盲矿及预测评价专题研究项目的开展,在皇城山银矿做了探索性研究,并收到一定效果。In subsequent prospecting for blind orebodies with primary halos in Huangchengshan, similarity discriminant analysis was applied and discriminant indices were constructed. Combined with other indices such as element contrast analysis of A1 vein, the work eventually made good progress. The achievement made supplies geochemical basis for evaluating the ore district, reducing the prospecting area and speeding up the exploration.
