摘要	Whole-rock geochemistry, zircon U-Pb and molybdenite Re-Os geochronology, and Sr-Nd-Hf isotopes analyses were performed on ore-related dacite porphyry and quartz porphyry at the Yongping Cu-Mo deposit in Southeast China. The geochemical results show that these porphyry stocks have similar REE patterns, and primitive mantle-normalized spectra show LILE-enrichment (Ba, Rb, K) and HFSE (Th, Nb, Ta, Ti) depletion. The zircon SHRIMP U-Pb geochronologic results show that the ore-related porphyries were emplaced at 162-156Ma. Hydrothermal muscovite of the quartz porphyry yields a plateau age of 162.1 +/- 1.4Ma (2 sigma). Two hydrothermal biotite samples of the dacite porphyry show plateau ages of 164 +/- 1.3 and 163.8 +/- 1.3Ma. Two molybdenite samples from quartz+molybdenite veins contained in the quartz porphyry yield Re-Os ages of 156.7 +/- 2.8Ma and 155.7 +/- 3.6Ma. The ages of molybdenite coeval to zircon and biotite and muscovite ages of the porphyries within the errors suggest that the Mo mineralization was genetically related to the magmatic emplacement. The whole rocks Nd-Sr isotopic data obtained from both the dacite and quartz porphyries suggest partial melting of the Meso-Proterozoic crust in contribution to the magma process. The zircon Hf isotopic data also indicate the crustal component is the dominated during the magma generation.
