| 摘 要： | The multimetal mine described in this paper contains W, Mo, Bi, Sn, Be, Cu, Pb,Zn and etc. Deposits occur in Upper and Middle Devonian carbonatite rocks and exhibite apparent zonal arrangement around a small granite body with respect to the elements mentioned above. At least four periods of magmatic intrusion and mineralization are recognized within this distriet. A comagmatic origin is indicated for all the deposits by geological setting, mineral assemblages, the geochemistry of ore elements,isotopic compositions of lead and sulfur as well as fluid inclusion studies. Ore metals are derived chiefly from the granite while wall rocks cannot be excluded as a minor supplier.
