GoethiteWikipedia

Goethite (FeO(OH); /ˈɡɜːrtaɪt/) is an iron bearing hydroxide mineral of the diaspore group. It is found in soil and other low-temperature environments. Goethite has been well known since ancient times for its use as a pigment (brown ochre).


Goethite: Mineral information, data and localities.

The most common simple iron oxide mineral. A weathering product of numerous iron-bearing minerals. Goethite may crystallize from a precursora not approved species called 'proto-goethite'. May also form due to mineralization of lichen (Parmelia conspersa) thalli

Goethite. Goethite is normally formed under oxidizing conditions as a weathering product of iron minerals ( e.g., pyrite, magnetite). Because it is formed near the surface, goethite is the major component of the gossan of iron sulfide deposits in locations such as


Goethite MineralPhysicalOptical Properties, Uses

Goethite is an iron oxide hydroxide, although manganese can substitute for up to 5 percent of the iron. It forms as a weathering product in the oxidation zones of


Goethite: The mineral goethite information and pictures

The Mineral goethite. 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.


Goethitean overviewScienceDirect Topics

Goethite (α-FeOOH) Goethite is the most common of the iron oxyhydroxides and is antiferromagnetic with a disordering (Néel) temperature of about 120°C (Hedley, 1971). Goethite has weak saturation magnetization and very high coercivity (Hedley, 1971; Rochette and Fillion, 1989). It dehydrates to hematite at about 300°C.
