The Daheishan Mo deposit is located in the eastern part of the Central Asian Orogenic Belt, NE China. Rhenium and osmium isotopes of molybdenites from the Daheishan deposit were used to determine the age of mineralization. Rhenium concentrations in molybdenite samples are between 17 and 30gg(-1). Analysis of seven molybdenite samples yields an isochron age of 168.0 +/- 4.4 Ma (2 sigma). Based on the geological history and spatial-temporal distribution of the granitoids, it is proposed that the Mo deposits in eastern China were related to the subduction of the Paleo-Pacific plate during Jurassic time.
