摘要：
Re-Os data for molybdenites from the Karkonosze massif (KM) provide ages of molybdenite crystallization from 326 +/- 1 to 310 +/- 1 Ma with one molybdenite at 213 +/- 1 Ma. Older molybdenite ages reflect two periods of post-magmatic pneumatolytic and hydrothermal activity during Visean-Westphalian time and the much younger molybdenite may indicate hydrothermal mineralization connected with tectonic activity in the Intra-Sudetic fault zone on the southern margins of the Zechstein basin in the Upper Permian.
