Data for: Localized grain scale processes recorded by large oxygen isotope variations in olivine-hosted melt inclusions from two MORB samples

Full characterization of olivine hosted melt inclusions from two MORB samples (major, volatiles, and trace elements of melt inclusions, oxygen isotopes of melt inclusions and olivine, Fo content of olivines)

Also, SIMS analytical conditions used for volatiles and trace elements and oxygen isotopes.
