Data for: Early Cretaceous lower crustal thickening and delamination: Constraints from cumulate rocks and adakitic lavas in southeast China

We presented new zircon U-Pb ages and Hf isotopes of the gabbro and diorite in the southeastern edge of South China, the representative cumulate of the arc lower crust derived from hydrous magmas. Also included here are contemporaneous adakitic lavas reported in the vicinity. Bulk-rock geochemical and Sr-Nd-Pb isotopic compositions of the cumulate and adakite are reported. Meanwhile, we compiled previously published dataset of the Cretaceous adakitic rocks and A-type granites that are widespread in South China.
