Seven molybdenite samples from greisen ore body and quartz vein tungsten ore body associated with black tungsten ore were chosen for Re-Os isotopic dating and model age of (141.4±2.2) Ma~(158.2±2.2) Ma were obtained. The isochrone age of molybdenites from greisen type tungsten-tin ore body is (156.8±3.9) Ma, which indicates that its mineralogenetic epoch is at the Middle Jurassic, corresponds to the second stage of early Yanshanian period. And the model age for the samples from greisen ore body and from quartz vein ore body are (150.7±2.4) Ma~(158.2±2.2) Ma and (141.4±2.2) Ma~(151.0±2.4) Ma respectively, which indicates that the mineralization time of the quartz vein ore body is slightly earlier than that of greisen ore body.
