A magma ocean origin to divergent redox evolutions of rocky planetary bodies and early atmospheres

A magma ocean origin to divergent redox evolutions of rocky planetary bodies and early atmospheres

Applying first-principles molecular dynamic simulations and thermodynamic modelling, the authors suggest a vertical oxygen fugacity gradient in magma oceans of Earth, Mars, and the Moon. Consequently, the study proposes larger planets like Earth to have stronger oxidized upper mantles than smaller b...
