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

Description

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. Supplementary Table 1 - Major and trace element of the bulk basanite Supplementary Table 2 -Microprobe analysis data with olivine (wt.%) Supplementary Table 3 - LA-MC-ICP-MS analysis data with xenocryst olivine for trace elements (ppm) Supplementary Table 4 - In-situ Fe-Mg isotope compositions of olivine xenocryst and modeling results
