Goethite mineral Britannica

Goethite, a widespread iron oxide mineral [α-FeO(OH)] and the most common ingredient of iron rust. It was named in 1806 for J.W. von Goethe, a German poet and philosopher with a keen interest in minerals. The name was originally applied to lepidocrocite [γ-FeO(OH)], a less common mineral with the s

Goethite Wikipedia

Goethite (/ ˈ ɡ ɜːr t aɪ t /) 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 paint pigment samples taken from the caves of

Dehydrogenation of goethite in Earth’s deep lower mantle

Jan 30, 2017· Abstract. The cycling of hydrogen influences the structure, composition, and stratification of Earth’s interior. Our recent discovery of pyrite-structured iron peroxide (designated as the P phase) and the formation of the P phase from dehydrogenation of goethite FeO 2 H implies the separation of the oxygen and hydrogen cycles in the deep lower mantle beneath 1,800 km.

Mineral Resource of the Month: Iron and Steel EARTH Magazine

Iron is one of the most abundant elements on Earth, but it does not occur in nature in a useful metallic form. Although ancient people may have recovered some iron from meteorites, it wasn’t until smelting was invented that iron metal could be derived from iron oxides. After the beginning of the Iron Age in about 1200 B.C., knowledge of iron- and steelmaking spread from the ancient Middle

Climatic interpretation of the Luochuan and Lingtai loess

Jul 15, 2004· Hematite and goethite, estimated from diffuse reflectance spectra, and magnetic susceptibility (MS) have been determined from both the Luochuan and Lingtai loess sections of the Loess Plateau of central China. Changing concentrations of these iron oxides and MS were used to determine paleoclimatic change.

What Is the Origin of Iron? Sciencing

Iron, one of the most abundant elements on Earth, helped give rise to entire civilizations and is the key ingredient in steel, without which many of our modern structures would not be standing. The story of iron's origins is astronomical, and it begins with the element being born from the explosion of stars.

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 drusy Quartz.
