Limonite mineral Britannica
Limonite is the catchall name widely applied to hydrous iron oxide minerals. Goethite [Fe 3+ O(OH)], which is hexagonal, is the most common of these mineralsindeed, in nature most FeO(OH) minerals ultimately become this phase.

It occurs naturally as yellow ocher (yellow or yellowbrown in color), the iron oxide being limonite, or as red ocher, the iron oxide being hematite. Click the link for more information. ) and as an ore of iron.
Limonite (/ l a m n a t /) is an iron ore consisting of a mixture of hydrated iron(III) oxidehydroxides in varying composition. The generic formula is frequently written as FeO(OH)Â· n H 2 O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely.
limonite (lmÂ´nt) or brown hematite (hmÂ´tt, hÂ´), yellowish to dark brown mineral, a hydrated oxide of iron, FeO(OH)Â·nH 2 O, occurring commonly in deposits of secondary origin, i.e., those formed by the alteration of minerals containing iron.
Limonite Mineral Information, photos and Facts
Limonite is a common ore of iron and is always secondary in its origin, formed through the alteration or solution of previously existing iron minerals. Pyrite is often found altered to limonite, the crystal form being at times preserved, giving limonite pseudomorphs.

Currently used for unidentified massive hydroxides and oxides of iron, with no visible crystals, and a yellowbrown streak. 'Limonite'is most commonly the mineral species goethite, but can also consist of varying proportions of lepidocrocite, hisingerite, pitticite, jarosite group species, maghemite, hematite, etc.
Limonite: an iron oxide used as pigment and iron ore
Limonite used to be considered a mineral, but today the name is a field term for amorphous iron oxides that have been used as yellow to brown ocher pigments and an impure ore of iron.
