Vein wolframite deposits of these two geochemical types were formed under different conditions. The wolframite-beryl-molybdenite-bismutite (native bismuth) type may be connected with high pH-Eh conditions whereas the wolframite-eassiterite-sulfide (copper, zinc, lead) type with low pH-Eh conditions. It is concluded that the two geochemical types of vein wolframite deposits are genetically related with two different geochemical types of granites in the Nanling Region.展开更多
