Located in the eastern Qinling Molybdenum Belt, the Balipo deposit is a porphyry Mo deposit discovered in recent years. This study provides the first highly precise dating of the mineralization and rock-forming in the Balipo Molybdenum deposit. The dating of zircon from Balipo granitic porphyry determined by LA-ICP-MS yields an age of 155.9±2.3 Ma. The Re-Os model ages of the deposit are between 152.8±1.1Ma～157.8±2.2Ma, and Re-Os isochrone age is 156.3±2.2 Ma . The zircon U-Pb and molybdenite Re-Os isotopic ages are quite close. The results suggest that the Balipo Molybdenum deposit was formed at least 10 Ma earlier than the Jinduicheng, Nannihu, Shangfanggou and Leimengou porphyry molybdenum deposits in the same molybdenum belt. On the basis of the accurately confirmed ages of the mineralization and rock-forming, the geodynamic evolution and forming mechanism are further discussed. The Balipo Molybdenum deposit formed during Episode A of the Yanshan Movement, That is, it is the early stage result of the conversion of tectonic regimes in East Asia, which has profound global geodynamic settings.
