On Earth, iron exists in the 2+ (ferrous) and 3+ (ferric) oxidation states so in chemical analysis of rocks, Fe concentrations are usually stated as % Fe 2 O 3 because the ferric oxidation state is moremon than ferrous oxidation state. On the Moon there is (effectively) no oxygen-bearing atmosphere so there are no iron 3+ iron minerals.
