Abstract��

Wanbaoyuan Mo deposit in Kuandian County, L iaoning Province located in the contact region between Shizhuzi granodiorite in Yanshan stage and Cambrian carbonate formation. Mo ore bodies are divided into quartz porphyry fissure, granodioritic fissure and cataclastic alteration zone quartz vein types according to surrounding rock properties and structural location. Test results and analysis of S, O, D isotopes show that metallogenic minerals come from remelting salic crust and ore-forming fluids are mainly from magmatic watermixed with a little ancientmeteoric water. There are two stages of ore formation in this region: skarn type Cu-Fe deposits ( ��stage) ; quartz vein and porphyry typesMo deposits ( ��stage) , mainly is porphyry type, and both of them are the products of postmagmatic-thermal fluid.
