The FeO/Fe2O3 ratio of magmas will depend on the oxygen fugacity, and the oxygen fugacity will itself be dependent on the composition of the magma and its gas content. The stability of the iron-bearing minerals depended on the FeO/Fe2O3 ratio, and the oxygen fugacity will, therefore, exert control on the fractionation trends of magmas. The oxygen fugacity is also significant for experimental work, as the fugacity of the charges should be the same as the fugacity of the magma (cf. Ulmer 1971).
