英文摘要	A number of statistics indicate that high content common Os universally occur in the molybdenite which is different from the previous study results. The common Os may occur in molybdenite as substitution atoms, therefore the molybdenite containing high content common Os has possibility in principle. Many analysis results demonstrate that high content common Os in the molybdenite may significantly affects the Re-Os model age. For most of molybdenite, the influence of common Os on the Re-Os model age cannot be ignored in case of Os-Common/Os-187 (Total) < 20, and the Re-Os model age should be calculated based on the method given in the paper rather than directly using the decay formula. Os-187/Os-188-Re-187/Os-188 isochron is made to obtain the initiallr Os-187/Os-188 value, then the non-radiogenic Os-187 in total Os is obtained according to the initial Os-187/Os-188 value and single sample common Os content. Model age is got according to the Re content and radiogenic Os-187 content finally.
