Ferrihydrite

Fe310O14(OH)2
Trigonal root IMA approved

Ferrihydrite is a hydrous iron oxide mineral with the chemical formula Fe^3⁺10O14(OH)2. It crystallizes in the trigonal crystal system and is classified under the Strunz classification as 4.FE.35. This mineral exhibits a dull to earthy luster, typically appears reddish-brown in color, and has a relatively low hardness and density compared to other iron oxides. It is commonly found in weathering environments and is part of the broader group of iron oxyhydroxides. Ferrihydrite is notable for its amorphous to poorly crystalline structure and is often associated with soil and sedimentary processes.

Overview

Ferrihydrite is a hydrous iron oxide mineral with the chemical formula Fe^3⁺10O14(OH)2. It crystallizes in the trigonal crystal system and is classified under the Strunz classification as 4.FE.35. This mineral exhibits a dull to earthy luster, typically appears reddish-brown in color, and has a relatively low hardness and density compared to other iron oxides. It is commonly found in weathering environments and is part of the broader group of iron oxyhydroxides. Ferrihydrite is notable for its amorphous to poorly crystalline structure and is often associated with soil and sedimentary processes.

Etymology

Ferrihydrite is named after its chemical composition, reflecting its iron-rich and hydrous nature.

Geological genesis

Ferrihydrite is typically formed through the oxidation and hydrolysis of iron-bearing minerals in surface and near-surface environments, such as soils and sediments. It is commonly associated with weathering processes and the early stages of iron oxide mineral formation.
