>Goethite, in itself, does not hold a status of a phenomenally beautiful mineral specimen, and hence, it is often brought to use in forming the backdrop for other minerals; vanadinite, for instance, is made a rather alluring mineral specimen with opalescent colors. Following is a list of its benefits and uses:>Description: Goethite is a common iron mineral. It often forms by weathering of other iron-rich minerals, thus is a common component of soils. It may form excellent pseudomorphs after the original minerals particularly pyrite or marcasite. Goethite may also be precipitated by groundwater or in other sedimentary conditions, or form as a primary ...

>Goethite often forms through the weathering of other iron-rich minerals, and thus is a common component of soils, concentrated in laterite soils. The formation of goethite is marked by the oxidation state change of Fe 2+ (ferrous) to Fe 3+ (ferric), which allows for goethite to exist at surface conditions. Because of this oxidation state change, goethite is commonly seen as a pseudomorph.>Goethite.
