Multiple sources of Cretaceous granitoids in northeastern Fujian, coastal area of southeastern China

The major elemental and oxygen isotopic features of Cretaceous granitoids in the coastal area of southeastern China cannot be adequately explained by existing Sr-Nd isotopic models of two-component crust-mantle mixing. In this paper, we report the whole-rock elemental, and Sr-, Nd-, and Hf-isotopes, and the zircon U-Pb age and Hf-O isotopic compositions for the Puqian, Danyang, Qingliangshan, Nanyu, and Qishan plutons in northeastern Fujian of...
