英文摘要	In this paper, we present newly obtained molybdenite Re-Os ages for the Chehugou copper-molybdenum deposit and the Yuanbaoshan molybdenum mineral locality from the Chifeng area on the northern margin of the North China block, combined with U-Pb zircon ages of the host granites. The Re-Os isochron age of six molybdenite samples from the Chehugou deposit is 257.5 +/- 2.5 Ma and one molybdenite sample from the Yuanbaoshan locality yields a Re-Os model age of 248.0 +/- 2.7 Ma. These ages clearly indicate the signature latest Permian to Early Triassic Cu-Mo or Mo mineralization that has not been previously recognized. Zircon LA-ICP-MS U-Pb dating shows that the host granites of the Chehugou deposit and Yuanbaoshan locality formed in the Late Devonian (376 +/- 3 Ma) and Late Permian (269 +/- 3 Ma), respectively, and is not of Jurassic age, as previously thought. The latest Permian to Early Triassic Cu-Mo mineralization is likely related to extension due to final closure of the Paleo-Asian Ocean and amalgamation of the Mongolian arc terranes with the northern North China block. The establishment of a latest Permian to Early Triassic age for mineralization should encourage renewed exploration aimed at the discovery of new Mo or Cu-Mo resources along the northern margin of the North China block.
