The Fuping Group, which has undergone amphibolite to granulite facies metamorphism, is the most widely distributed Archean strata in Fuping area of the Central North China Craton. The age of the Group is vital for probing the evolutionary history of the Fuping Complex. In this paper, LA-MC-ICP-MS (laser ablation multi-collector inductively coupled plasma mass spectrometry) was used to analyze the zircon U-Pb-Hf isotope of leptite in the Yuanfang Formation of the Fuping Group. The authors obtained two metamorphic zircon ages of 2 531±15 Ma and 1 943±16 Ma, respectively. Based on the internal structure of zircons and U-Pb ages, the authors chose the ²⁰⁷Pb/²⁰⁶Pb age of 2 549±4 Ma from the 2 549 Ma to 2 500 Ma detrital zircon domains as the maximal depositional age and confirmed the Yuanfang Formation between 2 550 Ma and 2 530 Ma. The zircon Lu-Hf isotopic analyses demonstrate that ¹⁷⁶Lu/¹⁷⁷Hf and ¹⁷⁶Hf/¹⁷⁷Hf are 0.000 289~0.004 262 and 0.281 255~0.281 791, respectively with ¹⁷⁶Hf/¹⁷⁷Hf_i and εHf(t) range being 0.281 230～0.281 623 and -5.86～13.62. The single-stage and two-stage model ages are in the range of 2 748~2 242 Ma and 2 810~2 272 Ma, respectively. On such a basis, the authors infer that the source of the Yuanfang Formation was mainly from Neoarchean TTG gneisses in the Fuping Compex, and the intensive crustal growth in the Complex was concentrated from 2.8 Ga to 2.6 Ga. In addition, the authors infer that metarmorphic ages of 2.5 Ga and 1.95 Ga may represent metamorphic events related to the initial and finial cratonization of the North China Craton.
