Carbonate melts have been proposed to exist in the lower mantle, but their interaction with other lower mantle melt compositions is poorly understo...
Investigating the Disproportionation of Iron in the Lower Mantle
TOWARD AN INTERDISCIPLINARY UNDERSTANDING ON THE STRUCTURE, COMPOSITION, AND DYNAMIC EVOLUTION OF THE LOWER MANTLE I ORAL
study of earth's deep interior | 15 december 2022
Kellie Swadba, Catherine A. Macris, Barbara Lavina...
It has been proposed that metallic iron exists as an accessory phase in the lower mantle, as a result of the disproportionation of Fe2+ to Fe0 and Fe3...
