Redox Systematics of Martian Magmas with Implications for Magnetite Stability


Introduction: Iron redox systematics of the high FeO shergottitic liquids are poorly known, yet have a fundamental control on stability of phases such as magnetite, ilmenite, and pyroxenes [1]. Experiments: We undertook experiments to constrain the Fe 3+ /Fe(tot) in high FeO glasses as a function of fO2, melt P2O5, temperature and pressure. We also… (More)
