Goethite: The mineral goethite information and pictures

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

limonite | mineral | Britannica

limonite, one of the major iron minerals, hydrated ferric oxide (FeO(OH)· n H 2 O). It was originally considered one of a series of such oxides; later it was thought to be the amorphous equivalent of goethite and lepidocrocite, but X-ray studies have shown that most so-called limonite is actually goethite.. The name limonite properly should be restricted to impure hydrated iron oxide (with ...

Limonite - an overview | ScienceDirect Topics

Iron oxyhydroxides form as weathering products that are often collectively called limonite. Orthorhombic goethite (αFeOOH) is the most important of these minerals and is a common constituent of soils and sediments. Goethite is antiferromagnetic with a Néel temperature of 120°C, but it has a weak superimposed parasitic ferromagnetism that ...
