Limonite, like goethite, usually forms from the weathering of more primary iron ores like hematite or magnetite, but also from the oxidation and hydration of iron-rich sulfide minerals and more complex stuff like olivine (iron plus some other metal silicate; extremely common in the earth's crust but not stable close to the surface).

Limonite is a ferric hydrate, conforming typically with the formula Fe 4 0 3 (OH) 6, or 2Fe 2 O 3.3H 2 O. Its hardness is rather above 5, and its specific gravity varies from 3.5 to 4. In many cases it has been formed from other iron oxides, like haematite and magnetite, or by the alteration of pyrites or chalybite.

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.

Currently used for unidentified massive hydroxides and oxides of iron, with no visible crystals, and a yellow-brown streak. 'Limonite' is most commonly the mineral species goethite, but can also consist of varying proportions of lepidocrocite, hisingerite, pitticite, …

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 .

Limonite is another ore of iron, this time with a chemical formula of FeO(OH)·nH 2 O, although it can be rather variable in compositions so could have other formulas, and is not considered a true mineral because of the variability of structure and is a mixture of other minerals.

Goethite is a common mineral, and is a frequent matrix material for other more aesthetic minerals. It is usually a dark, uninteresting mineral, though specimens from a handful of locations (especially Colorado) are remarkable for their delicate and beautiful crystal growths and velvety botryoidal growths. Goethite is also frequent as black crystal sprays that form within geodes on drusy Quartz.

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