摘　　要：在分析了武义地区构造、岩性、地球化学和现有萤石矿床蚀变类型和编制出１：５００００遥感解译地质图基础之上，提出本区的萤石控矿因素及遥感找矿标志，建立遥感找矿模型。用主成分分析方法提取与萤石矿化密切相关的硅化、高岭土化蚀变信息，用“证据权重模型”法进行区域找矿预测；找到了断裂硅化蚀变带。On the basis of geological intertation of TM images, the relationships between fluorito deposits and structures, lithologies, volcanic. features and geochemistry in Wuyi area, Zhejiang Province, were analyzed The fluorite metalloged model was established. The method of feature oriented principal component analysis was ed to extract silicic and kaolinitic alteration information from the TM data, Which are important al alteration types for regional mineralization. Finally, the method of 'Weights of evidence modeling' was ed to integrate information derived from remote sensing, geology and geochemistry, Which was then applied to map fluorite deposit potentials.
