英文摘要	Tongling is one of the most significant ore cluster area in the Middle-Lower Yangtze River Cu-Au-Fe-Mo metallogenic belt. The Fenghuangshan Cu deposit is a typical skarn type Cu deposit in the Tongling ore cluster area. In this study we yield molybdenite Re-Os model ages ranging from 139.1 +/- 2.4 to 142.0 +/- 2.2 Ma and the isochronal age 141.1 +/- 1.4 Ma. The results show that Cu mineralization of the Fenghuangshan Cu deposit occurred at the Early Cretaceous, which are slightly younger than quartz monzodiorite and granodiorite(144.2Ma, zircon U-Pb age). The ages indicate close temporal relations between Cu mineralization and magmatism. Our study is consistent to previous studies that Cu mineralization occurred at the Mesozoic second mineralization stage, responding to the Mesozoic lithosphere delamination event in south of China.
