Prolonged crustal storage for mantle xenolith-bearing basanite lava

Supplementary Table 1 provides the whole-rock major and trace element compositions of the host basanite containing the olivine xenocrysts. Tables 2 and 3 present the major and trace element compositions of olivine xenocrysts, phenocrysts, and matrix. Table 4 includes the Fe-Mg isotopic compositions of olivine xenocrysts, and the results of diffusion modeling based on these isotopic data. Table 5 provides the major elements in titanomagnetite from the Hannuoba alkaline basalt (wt%) and the number of cations based on four oxygen atoms.
