英文摘要	Rangnim Massif in North Korea is an important constituent part of the Sino-Korea Craton and the study of its rock assemblages, geochronology and metamorphic and deformation features will greatly influence the thorough interpretation and understanding of the geological evolution of the North China Craton and the whole northeastern Asia continent. In this study, we present the U-Pb dating and trace element analysis results of zircons from three granitoid gneisses from the Rangnim Complex, at the southeastern margin of the Rangnim Massif. Three gneissic samples give protolith magmatic ages of 2521 similar to 2567Ma and they also record the Paleoproterozoic (1. 87 similar to 1. 89Ga) tectonothermal event as certified by the different extend of recrystallization of zircons and the accompanied Pb-loss, and also the formation of new metamorphic zircons. Based on the results of this study and a synthesis of other studies, we proposed that the scale of the Archean basement rocks of the Rangnim Massif might be much larger than the several locations identified from the south and the east margin of the Pyongnam Basin. All the identified Archean gneisses in the Rangnim massif experienced strong Paleoproterozoic metamorphic overprinting and anatexis with ages similar to those reported from the whole North China Craton. This similarity likely suggests that the Rangnim massif might have amalgamated with the NCC to form a coherent continent before this Paleoproterozoic episode of tectonothermal event.
