Phantom recycled carbonates and mantle pyroxenites: insight from the low-δ26Mg intraplate basaltic province across central-eastern Asia

This dataset includes 1) Major, trace-element and Sr-Nd-Pb-Mg isotope data for Langshan basalts and lamprophyres, 2) Compilation of major, trace-element and Mg isotope data for the post-110 Ma intraplate basaltic magmatic province in central-eastern Asia, 3) Compiled experimental melt compositions from carbonated and uncarbonated rocks. and 4) Modelled δ26Mg and pyroxenitic mass contributions for adiabatic melts from mantle sources containing variable fractions of silica-deficient pyroxenite
