Structural features of south Hubei Province along the northern margin of the Mufushan pluton and structural ore-controlling of polymetallic deposits

[Objective] An intensive Early Cretaceous magmatic-hydrothermal metallogenic system occurred in the Mufushan area, central Jingnan Orogen. The Jingnan Orogen in the South China Block resulted from the accretion and subsequent collision of the Yangtze and Cathaysia blocks during the Early Neoproterozoic, consisting of Li-Be-Cs-Nb-Ta rare metal deposits and Pb-Zn-Cu-Au-Sb nonferrous metal deposits. The northeast Hunan Province and the south Hubei Province are located to the
