Goethite: Distribution, Formation & Composition

Goethite (/ˈɡɜːrtaɪt/, US also /ˈɡoʊθaɪt/) is a mineral of the diaspore group, consisting of iron(III) oxide-hydroxide, specifically the α-polymorph. It is found in soil and other low-temperature environments such as sediment. Goethite has been well known since ancient times for its use as a pigment (brown ochre). Evidence has been found of its use in…
