Valence/Spin States of Iron in Peridotite Glass to Megabar Pressure Implications for Dense Iron‐Rich Silicate Melt at the Bottom of the Mantle

Abstract We have conducted high‐pressure electrical conductivity and Mössbauer spectroscopic measurements of peridotite glass as an analog of silicate melts. We observed the shoulder feature in the Mössbauer spectra above 60 GPa due to the emergence of the new Fe2+ component, which could be associat...
