英文摘要Caozhuang Group (or Caozhuang supracrustal sequence) in Eastern Hebei, North China Craton (NCC) may represent the oldest supracrustal unit of China. Abundant Eoarchean and Paleoarchean detrital zircons (up to 3.88 Ga) in paragneisses of Caozhuang Group provide valuable memories of the earliest crustal evolution of China. There still remains confusion about the deposition time of the Caozhuang group, the origin and the igneous host rocks of their detrital zircons, and the earliest crustal evolution of NCC. In this study, the combined U-Pb and Lu-Hf datasets provide evidence that similar to 3.3-3.4 Ga is a probable estimate for the maximum deposition age of the Caozhuang Group. In addition, the increasingly subchondritic Hf isotopic compositions between 3.9 and 3.4 Ga reflected by the broadly linear Hf isotope evolution defined by Caozhuang detrital zircons may support the protracted intra-crustal reworking of a long-lived mafic source in composition with Lu-176/Hf-177 of 0.027. The Lu-Hf composition of the mafic source is similar to the average value of ocean floor basalts (Lu-176/Hf-177 = 0.028) and Eoarchean-Paleoarchean Caozhuang mafic rocks (Lu-176/Hf-177 = 0.026) in the same area. Based on the similarities between Caozhuang detrital zircons and TTG-hosted zircons of Anshan complex, as well as the significant differences with other Archean ancient complexes, the Anshan complex, where the oldest rock unit of China is preserved, may be the suitable host rocks for Caozhuang detrital zircons.
