Tongmugou copper deposit is one of the important copper deposits in Zhongtiaoshan of Shanxi��and the main ore bodies occurred in strata with straitiform or stratiform-like shape�� There were many molybdenite hydro- thermal quartz-sulfide veins distributed along the cross fracture and the interlayer fracture zone�� The ��e-Os isotopic ages of molybdenite indicated that the weighted average age of 1 901 ± 24 Ma��and the isochrone model age of (1 870 ±27) �� (1 916 ±29) Ma��which is closely agreed with the time of Zhongtiao movement�� The formation of molybdenite is closet connection with granite porphyry��and the source of metallogenic material may come from the magma mixing of crust and mantle��
