Abstract : to the principle and project that tu guangazhi proposed in 1990, the gold ore deposits in qinling ( shaanxi ) may be classified into fouowing types : archean high - grade gneiss type, fine grained fragmental rock - carbonate rock - silicilith type, metamorphic fragmental rock type, volcanic rock type, explosive breccia type, intrusive rock exo - and endo - contact zone type. inthis paper, the geological characteristics, metallogenic geological setting, the source of ore - forming materials, digenic mechanism and metallogenetic epoch of gold ore deposits are also discussed
