The K-rich granite took limited volumes of the continental crust in the early earth (>2.6 Ga). Studies on ancient granite will provide great evidence for revealing the geological history of the crust. In this paper, we carry detailed studies on the geology and zircon U-Th-Pb-Hf isotopic composition of the Paleoarchean granite, which is exposed in the Anshan Gongchangling area of the North China Craton (NCC). The studied Paleoarchean granite, which is occurring as an enclave in the regional large-scaled of Mesoarchean (2.9 Ga) granite with similar tectonic feature to the latter, is composed of K-feldspar (40%~60%), plagioclase (10%~30%), quartz (30%) and minor mica. Most magmatic zircons from the Paleoarchean granite have varying Th and U contents of 100×10^-6~600×10^-6 and 400×10^-6~1 500×10^-6, respectively, with relatively high Th/U ratios (0.10~0.93). 13 concordant analysis yielded meaning weighted average age of 3 337±24 Ma(MSWD=1.5), interpreted as the emplacement time of the granite. And the inherited zircons formed at 3.76~3.60 Ga. The analyzed zircon grains yielded initial ¹⁷⁶Hf/¹⁷⁷Hf_i ratios of 0.280 391~0.280 857 with Hf depleted mantle modal ages (t_DM1) of 3 856~3 327 Ma. The differences of Hf isotopic compositions suggested that ① an ancient continent nucleus with multiple magmatic records had been formed before the end of the Paleoarchean in the Anshan area; ② the stabilization of the early crust should not be synchronous during the geological history. Crustal stabilization and differentiation had been carried out locally, early before the amalgamation of the continental basement of the NCC at ~2.5 Ga.
