摘要: Zircon U-Pb dating indicates that the fuchsite quartzite in eastern Hebei Province was derived from weathering and erosion of 3.6–3.8 Ga granitic rocks.In-situ zircon Hf analyses show Lu-Hf isotopic system remained closed during later thermal disturbances. Zircons with concordant ages have model about 3.8 Ga, suggesting a recycling this ancient crust. The ∼3.8 zircons similar compositions to those chondrite, indicating their source rocks (granitic rocks) were partial melting juvenile crust which originated mantle without significant crust-mantle differentiation. Therefore, it is proposed there no large-scale crustal growth before Province. Considering data other areas, concluded most North China Craton probably formed at 4.0 possibility find older than very limited.
