Goethite Mineral | Physical Optical 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 veins of iron minerals, such as pyrite, magnetite and siderite. Goethite may occur with these minerals in the gossan, or iron hat, which is the weathered capping of an iron ore deposit.

goethite Academic Dictionaries and Encyclopedias

a widespread iron oxide mineral [α-FeO()] 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()], a less common mineral with the same chemical composition as goethite but with a different crystal structure.

Iron(III) oxide-hydroxide Wikipedia

Iron(III) oxide-hydroxide or ferric oxyhydroxide is the chemical compound of iron, oxygen, and hydrogen with formula FeO(OH).. The compound is often encountered as one of its hydrates, FeO(OH) ·n H 2 O [Rust]. The monohydrate FeO(OH) · H 2 O (CAS , C.I. 77492) is often referred to as iron(III) hydroxide Fe(OH) 3, hydrated iron oxide, yellow iron oxide, or Pigment Yellow 42

Iron Oxide Pigments (Natural) energymining.sa.gov.au

Natural Iron oxide and hydroxide minerals occur in a variety of colours and have been used as pigments since prehistoric times. In France and northern Spain, cave paintings using iron oxide pigments have been dated at ~30 000 years and, in Australia, Aborigines mined ochre which was transported throughout the continent via an extensive nationwide trade network.

Goethite and similar minerals | Frankensaurus

Chloride-containing iron oxide-hydroxide mineral, formed by the weathering of pyrrhotite (Fe 1−x S). Often described as the β phase of anhydrous ferric oxyhydroxide, but some chloride ions are normally included in the structure, , so a more accurate formula is. Wikipedia

CSMS GEOLOGY POST: GOETHITE FROM THE PIKES PEAK

The reason my memory was recently jogged about iron oxide minerals is that Mr. Rockhounding the Rockies (rockhounding kw.blogspot), one of the premier collectors of minerals from the Pikes Peak Batholith (age around 1.08 Ga) gifted me an absolutely gorgeous specimen of goethite, an iron oxide-hydroxide [FeO(OH)].It reminded me, again, that not all iron oxides/hydroxides look like rust

Goethite HyperPhysics Concepts

This goethite sample was formed after pyrite when chemical conditions changed. It retains the pyrite's basic cubic shape, so it is a pseudomorph. Pyrite is an iron sulfide, and goethite is an iron oxide hydroxide. This compares the goethite
