1. Ferric iron content of garnet and spinel from mantle rocks plotted as a function of the calculated log fO2 using equations (9)–(11).
Ferric iron content of garnet and spinel from mantle rocks plotted as a function of the calculated log fO2 using equations (9)–(11). Data from garnet- and spinel-bearing peridotites are from Miller et al. (2016) and Stagno et al. (2013). Data on eclogites are from Stagno et al. (2015, and references therein) and Aulbach et al. (2017).
