Hydrated Iron Ore

Limonite is not a true mineral but a mixture of similar hydrated iron oxide minerals. Most of limonite is made up of Goethite. Massive Goethite and Limonite can be indistinguishable. Limonite forms mostly in or near oxidized iron and other metal ore deposits, and as sedimentary beds.
