Introduction. Reducing ilmenite (FeTiO 3) to produce oxygen, iron, and titanium in a lunar context has produced a number of proposals, many of them specifically aimed at oxygen production. Ilmenite is attractive for this purpose as the iron oxides it contains require less energy to reduce than any other oxide on the lunar surface.

Most analyses of natural iron-titanium oxides contain small but significant amounts of minor components. In order to determine the "mole" fractions of endmember ilmenite and ulvcispinel in coexisting oxides for geothermometry, a new recalculation scheme is proposed based on models of ionic substitution. This new scheme is consistent with a new
