| Abstract: | The silver polymetallic deposits of Dongwushan, Zhejiang, China occurs in the conjugated part of regional tectonic faults. Its hosted rocks are composed of breccia, subvolcanic rocks and cataclastic sandstone which are characterized by rather complex genesis and composition. Its host structure is the compressional belt of secondary faults with the approximately E-W strike. The orebodies occur in vein styles of mineralization, containing Pb, Zn, Ag and Cu as the mainly useful components. Tonnages of the ores belong to the mid - scale. Its mineralization shows vertical zoning obviously. Silver polymetallic deposits at Dongwushan is genetically related to the subvol canic type of moderate temperature thermal deposits. |
