Medium-scale Fe-Cu-Co-(Au-Ag-Mo) skarn, hosted in the contact zone of Mesozoic granodiorite and Neoproterozoic dolomite of the Wumishan Formation. The orebodies are lenticular or lensoid in skarns, and stratiform in metasomatized dolomite. Seven zones occur along the contact: a granodiorite zone, an altered granodiorite zone, a garnet-epidote-vesuvianite skarn zone, a diopside zone, a magnetite-humite-diopside skarn zone, a wollastonite skarn zone and a serpentinite-altered dolomite zone. There are five types of ore mineral associations: (1) magnetite, (2) pyrite-bearing magnetite, (3) pyrrhotite and Co-bearing chalcopyrite, (4) pyrite-bearing chalcopyrite, and (5) veined chalcopyrite. The minerals occur in masses, disseminations, veins and veinlets, and display idiomorphic, xenomorphic, replacment and colloidal textures. Four skarn stages occur: (1) a scapolite stage with scapolite, wollastonite, vesuvianite, garnet and diopside; (2) a magnetite stage with magnetite, humite, phlogopite, sericite, tremolite and actinolite; (3) a quartz-sulphide stage with sulphides, chlorite and sericite; and (4) a carbonate stage with calcite and fluorite.
