What the heck is limonite?
Limonite is a mixture of fine-grained hydrated iron oxides. It is chemically similar to goethite (HFeO2), but varies from ideal goethite by having more water. Although goethite is a very common component, limonite can also contain many other minerals. Some are polymorphs of goethite: lepidochrocite, akaganeite and feroxyhyte.
