Continental thermal blanketing explains the compositional dichotomy of the diffuse basaltic province across central-eastern Asia

This dataset includes (1) Ar-Ar dating of the Change basalts; (2) major- and (3) trace-element and Sr-Nd-Pb isotope systematics of the Chaoge basalts and (4) compiled element and isotopic data for Cretaceous-Cenozoic basaltic rocks across the central-eastern Asia continent
