    Description Limonite is a general term for a mixture of fine-grained iron oxides generally dominated by goethite but also possibly containing hematite lepidochrocite and other minerals. It forms from the weathering of other iron minerals and may be precipitated by iron rich surface or ground water.

    Goethite varies in colour from yellow-brown to red. It is composed of about 80 to 90 percent Fe 2 O 3 and approximately 10 percent water. When dehydrated goethite forms hematite upon hydration goethite becomes limonite. For detailed physical properties see oxide mineral (table).

    Goethite is an iron oxyhydroxide containing ferric iron. It is the main component of rust and bog iron ore. Goethite s hardness ranges from 5.0 to 5.5 on the Mohs Scale and its specific gravity varies from 3.3 to 4.3. The mineral forms prismatic needle-like crystals ("needle iron ore") but is more typically massive.
