Systematic isotopic age-datings on Wunugetushan porphyry Cu-Mo deposit in NE-Inner Mongolia by several methods were reported by this paper as: the single grain zircon U-Pb age of 188.3±0.6 Ma; the whole rock Rb-Sr age of 183.9±1.03 Ma, and the altered sericite K-Ar age of 182.3-184.7 Ma. They represent the ages of beginning crystallization after magma emplacement, magma cooling, and hydrothermal alteration, respectively. So it is fully approved that the intrusive and metallogenic epoch of the Wunugetushan Cu-Mo deposit is in early Yanshanian (Early Jurassic) rather than late Yanshanian epoch as suggested before. The K-Ar ages (138 Ma) determined formerly perhaps reflect the later volcano-intrusive thermal events after mineralization.
