WebIron oxides Magnetite (Fe2+Fe3+2O4) and hematite (Fe3+2O3) are oxides of iron. Magnetite occurs as a trace to minor mineral in several kinds of meteorites. Rubin (1997a) states that it is the “principal oxide phase in the CK chondrites,” a rare type of meteorite (0.3%). Their high iron abundance is about 25–31% by weight. Over half of this is present in metallic form, making these meteorites strongly magnetic despite the stony chondritic appearance.
