In order to make full use of the advantages of exploration geochemistryin ore prospecting, we have used the method similar to that in the study ofgeochemical characteristics of veinlike hydrothermal metallic deposits to performtrial geochemical prospecting in the Badu fluorite deposit of Longquan coun-ty, Zhejiang province. The purpose for this study is (1) to get to know geo-chemical characteristics of wall rocks. stream sediments and water madiahosting this type of fluorite deposits in the process of mineralization, and (2)to find out features of primary and secondary anomalies in this type of oredeposits. The data obtained are expected to provide some geochemical groundsfor the prospecting and evaluation of this type of ore deposits in unknownareas. Studies show that primary anomalous elements associated with the formation of fluorite deposits include F, As, Sb, Ca, Ag, Mo, Y in Group I and Na, Mg, Al, K, Ti, Ba, P, Nb, Pb in Group II with elements in Group I being positive anomalous ones and those in Group II being negative anomalous ones. Primary anomalous of all these elements exhibit'tonal arrangement. Axial zoning of the positive anomalous elements are in upward succession F- Ca-As- Sb-Y-Ag-Mo. Stream sediment and heavy sand survey indicates that placer fluorite anomalies and F anomalies might have formed in drainage system near the denuded fluorite deposit, SO that fluorite may serve as an indication mineral and F as an indicator element in ore prospecting. Hydrogeochemical studies suggest that F^- and Ca⁺⁺ hydrochemical anomalies may appear within the fluorite orefield, which are of some significance in indicating enrichment locality of orebody and extension of ore zone.
