... within the MgO-FeO-SiO 2 system bridgmanite is not a binary but at least a ternary solid solution because of the presence of ferric Fe. Ferric iron can be suppressed only for less than 4 atom% Fe in bridgmanite ( Parise et al. 1990 ). Vanpeteghem et al. (2006a) presented structure analyses that showed...

The best examples of a transition from extrinsic to intrinsic behavior are observed in data from oxides (e.g. Al 2 O 3 , MgO, FeO) reacted with a gas phase, O 2 or CO 2 .
