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.
