Late Neoarchean granitoid gneisses are widely distributed in the Early Precambrian metamorphic basement of the Liaonan Block, the North China Craton (NCC), and record important information on the formation and evolution of the continental crust in the Early Precambrian. In this study, we present zircon LA-ICP-MS U-Pb ages, trace element compositions, and Lu-Hf isotopic data from four granitoid gneiss samples collected from the Liaonan Block. Most zircons exhibit oscillatory zoning and high Th/U ratios (0.18～2.21), along with REE patterns characterized by depleted LREEs and enriched HREEs, consistent with a magmatic origin. The ²⁰⁷Pb/²⁰⁶Pb weighted mean ages of the four granitoid samples are 2 529±10 Ma (MSWD=0.12, n=14), 2 475±27 Ma (MSWD=3.1, n=13), 2 502±15 Ma (MSWD=2.7, n=14), and 2 478±8 Ma (MSWD=0.81, n=25), respectively, recording the magmatic events related to crustal differentiation during the late Neoarchean. Zircon Hf isotopic compositions show positive εHf(t) values (+0.11 to +5.29), with two-stage model ages (t_DM2) ranging from 2.9 to 2.7 Ga, suggesting the granitoids were derived mainly from partial melting of juvenile crust formed during this period. A few zircons yield negative εHf(t) values (-3.2 to -0.8) and older t_DM2 ages of 3.12～2.90 Ga, reflecting the involvement of ancient reworked continental crustal components older than 2.9 Ga. Combining the new results with published zircon Hf isotope data, it has been demonstrated that the Liaonan Block experienced major crustal growth during 2.9～2.7 Ga and crustal reworking at 2.5 Ga and 2.47 Ga, which were driven by upwelling mantle. The resulting widespread potassic granitic rocks signify the stabilization and cratonization of the block.
