Goethite feo oh, named after the german polymath johann wolfgang von goethe 17491832 goethite is an iron bearing oxide mineral that often forms through the weathering of other iron-rich minerals, and thus is a common component of soils.The formation of goethite is marked from the state of change of fe2 to fe3, which allows for goethite to exist at surface conditions.
