英文摘要	Recognizing and characterizing the basement affinity of terranes presents a critical task for establishing the link between the Korean Peninsula (KP) and the North China Craton (NCC) since Archean on. This study aims to bridge the gap in the characterization of the Precambrian basement rocks in the KP by documenting the Undokdong meta-intrusive complex in the Chongjin region, the Kwanmo Massif. SIMS zircon U-Pb dating on three representative samples from the complex yielded magmatic crystallization ages from 2. 53 to 2. 51Ga. In terms of their petrological and geochemical traits, the protoliths of these metamorphic rocks can be recognized as quartz diorite and potassic granite, and compare well with the classic magmatic charnockite suites in the world. Synthesizing these features with the variable zircon epsilon(Hf) (t) values from -1. 7 to + 10. 5 in the three samples, we infer that the Undokdong meta-intrusive complex might originate from the high-T and CO2-rich fluid-fluxed partial melting of basaltic lower crust and subsequent fractionation, thus representing typical products of magmatic arcs on an active continental margin. Given a possible tectonic link with a Neoarchean arc root, these rocks could present a spatial reference for defining the consistency in tectonic affinity between the Kwanmo Massif and the Helong/Qingyuan terrains in the eastern NCC, thus leading to the characterization of an Andean-type active continental margin across these terrains during Neoarchean.
