Petrogenesis of the Cretaceous Zhangzhou batholith in southeastern China: Zircon U-Pb age and Sr-Nd-Hf-O isotopic evidence

► Cretaceous magmatism in Southeast China related to extension. ► Zircon Hf-O isotopes show multiple sources in the origin of Cretaceous magmatism. ► Petrogenesis of Cretaceous I- and A-type granites in Southeast China. ► The role of mantle-derived magma in petrogenesis of A- and I-type granites.
