Located in the inside and outside contact zone of granite porphyry, the Getingkeng molybdenum deposit is a medium-sized porphyry deposit in southern oft-com:office:smarttags" />Jiangxi Province. Re-Os isotopic dating of 7 molybdenite samples from the mineralized quartz veins of Getingkeng deposit has yielded a precise isochron age of (159.4±1.6) Ma and a weighted average model age of (158.8±1.3) Ma. The intercept of isochron is (0.001±0.055) ng/g, and the MSWD is 1.7. Getingkeng molybdenum deposit formed in the Mid-Late Middle Jurassic, the mineralization age corresponds to the second mineralization stage (170~150 Ma) in the Late Jurassic of South China, consistent with the tungsten-tin mineralization around 160 Ma within the region. South molybdenum mineralization occurred in a row of 165~90 Ma.oft-com:office:office" />
