Geochemical and Hf-Nd isotope data of Nanhua rift sedimentary and volcaniclastic rocks indicate a Neoproterozoic continental flood basalt provenance

► Report first integrated Hf-Nd isotope and elemental analyses for the Nanhua Basin. ► εNd(t) values of studied sediments higher than those of the Neoproterozoic granites. ► Suggests sediments sourced from eroded continental flood basalts.
