Yangxikeng molybdenum deposit is located in the central south of Yushan polymetallic metall-ogenic belt. The regional geology, deposit geology and orebody characteristics of Yangxikeng molybdenum deposit in Ganxian of Jiangxi were studied, and molybdenite collected from quartz vein was measured by monomineral Re-Os isotopic dating. The results show that there is no stratum outcrop but only fine grained biotite granite （3bγ5^2-2） in the mining area, and the periphery is middle coarse grained porphyraceous biotite granite （1-2ρbγ5^2-1）, and the contact relationship of them is intrusive; mineralization type of orebody is endomorphie zone quartz veinl three mineralization belts in the mining area, which is controlled by near NS-trending tectonic, appear parallelly in group, and NS-trending tectonic provides occurrence space for orebody. Re-Os isotopic dating results of 8 molybdenite samples from Yangxikeng molybdenum deposit indicate that the isochron age and weighted average model age are （156.09±0.77） Ma and （155.78 ± 0. 81）Ma, and the high precious age is the mineralization age of molybdenum deposit and matches the mineralization age of Wu-Sn deposit in Nanling area.
