英文摘要As the dominant component of the continental crust, Archean intrusive granitoids can provide significant insights into the growth and evolution of the early crust. In this study, we report a systematic geochronological and geochemical study on a tonalite-trondhjemite-granodiorite (TTG1)-granites (G2)-quartz monzonite (QM) assemblage in the northeastern North China Craton (NCC). Zircon U-Pb dating shows that they were emplaced during 2506-2549 Ma. Their geochemical features, such as REE concentrations, patterns and ratios, superchondritic Nb/Ta ratios, and similarity to the HP-MP TTGs, suggest residues of garnet-amphibolite-to eclogitefacies. TTGs in Group I show high Sr and low Y concentrations and negligible/pronounced negative Eu anomalies, reflecting rare or a small quantity of plagioclase residue. Positive Eu anomalies of Group II possibly indicate involvement of varying amount of accumulative plagioclase, and that garnet fractionation also plays a role. High MgO, Mg#, Cr and Ni, and positive epsilon Hf(t) varying from juvenile to evolved signatures, suggest that the TTGs were generated under a continental arc setting. The granitic rocks (G2-QM) were generated by melting of predominant TTGs and subordinate metasedimentary rocks, with late-early Neoarchean TTGs, Mesoarchean TTGs, and Eoarchean crustal material in the NCC involved. Isotopic evidence shows that 2.7-2.9 Ga crustal reworking predominates the formation process of the granitoids. The study area witnessed a long period of crust extraction from Eoarchean to the end of Neoarchean. Subduction-related magmatisms at late Neoarchean are widespread in the world.
