| Abstract: | The metallogenic geological setting and ore-controlling condition of the Mesozoic volcanic rocks hosted Au-Ag deposits in the eastern China, including the relation of mineralization to basement,volcanic formation, sub-volcanic rock and structure are discussed. These deposifs are classitied into three genetic types, and the main geological characteristics including host rock, ore -bearing structure,shape of ore body, ore formation, ore zoning and alteration are reviewed. |
