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.

文章选取云英岩型矿体及上部石英脉型钨矿体中与黑钨矿共生的辉钼矿7件，进行Re-Os等时线年龄测定，得到其模式年龄为(141.4±2.2) Ma~(158.2±2.2)Ma，其中云英型钨锡矿体中辉钼矿等时线年龄为(156.8±3.9)Ma，成矿时代为中侏罗世，对应于燕山早期第二阶段；从云英岩矿体中样品模式年龄为(150.7±2.4)Ma~(158.2±2.2)Ma，石英脉型矿体中样品模式年龄为(141.4±2.2)Ma~(151.0±2.4)Ma。
