A prolonged crustal storage for mantle xenolith-bearing alkali basaltic lava

This is a dataset on mantle xenocrysts, including whole-rock data of the host magma, major and trace element data of olivine xenocrysts, Fe-Mg isotope data, as well as data on olivine phenocrysts and the matrix. The data for olivine xenocrysts are all compositional profiles.
