Magnetite, with chemical formula fe3o4, is an iron ore found in igneous, metamorphic rocks. it belongs in the same group of iron ore as the hematite or the maghemite. magnetite is a chemical compound of iron and oxygen and therefore an oxide. magnitite is physically rather stable, as it is a octahedral crystal.
