    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.
