Olivine-hosted melt inclusion, clinopyroxene, and groundmass compositions from tephras of Buldir volcano, western Aleutian arc

This dataset includes in-situ major element compositions of olivine-hosted melt inclusions, host olivines, clinopyroxene crystals, and groundmass of mafic tephras from Buldir volcano. This dataset additionally includes in-situ measurements of H2O, CO2, S, Cl, and Fe3+/∑Fe ratios of the olivine-hosted melt inclusions. Data for melt inclusions are measured values, not corrected for post-entrapment crystallization.
