Abstract:The Pre- Devonian crustal evolution of the Yangtze craton has long been a hot topic in geosciences. This paper reports the zircon U- Pb ages and Hf isotopic compositions of the clastic sedimentary rocks of the Silurian Fentou Formation and the Devonian Yuntaiguan Formation in the Yusunshan section of the Wuhan area in the northern margin of the Yangtze craton. The results show that the youngest detrital zircons in the Fentou Formation and the Yuntaiguan Formation in Wuhan are 430±5 Ma and 415±5 Ma, respectively, limiting their sedimentary ages to the Middle Silurian and Late Devonian. Zircon Hf isotopic features reveal that their source area formed a small amount of juvenile crust in the Mesoarchean, Neoarchean and Neoproterozoic, while the reworking of the ancient crust mainly occurred in the Neoarchean, Neoproterozoic and Paleozoic. The most significant juvenile crustal growth period is Paleoproterozoic. By comprehensively comparing the zircon U- Pb ages, trace elements and Hf isotopic compositions of the eastern and western segments of the northern Yangtze craton, it is suggested that the Yangtze craton may be composed of a series of individual components which have their own crustal evolution processes, rather than a unified Early Precambrian basement.
