Compositional characteristics of wolframite in tin deposits, Dupangling, Guangxi

  • Gan Guoliang

Statistical data on major, trace and rare-earth elements in wolframite from the quartz vein-and greisen-type tin deposits in the Dupangling orefield reveal: (1) The components in wolframite can be divided into two relatively independent groups: the WO3-Nb-Ta-Sc-REE group, in which WO3 is negatively correlated with the others and the FeO-MnO-Sn group, in which MnO is negatively correlated with the other two; (2) In general, REE fractionation is not significant, reflected mainly by the separation of Eu from other REE’s. LREE and HREE increase or decrease simultaneously, with HREE being more variable; (3) Nb, Ta, Sc, REE substitute for W, and Sn may enter into wolframite lattice accompanied by Fe-Mn substitution; (4) In contrast to wolframite in quartz veins, which is poor in REE, Nb, Ta and Sc and has highδ Eu values and LREE / HREE and Nb/Ta ratios, wolframite in greisen is rich in REE, Nb, Ta, Sc and has lowδ Eu values and LREE/HREE and Nb/Ta ratios; and (5) The contents and ratios of trace elements and REE partitioning parameters of wolframite can be used as guide for prospecting.
