Goethite Wikipedia

Goethite / rtat / is a mineral of the diaspore group, consisting of iron III oxidehydroxide, specifically the quotquot polymorph. It is found in soil and other lowtemperature environments such as sediment. Goethite has been well known since ancient times for its use as a pigment brown ochre.

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.

IronIII oxidehydroxide Wikipedia

Siderogel is a naturally occurring colloidal form of ironIII oxidehydroxide. Goethite and lepidocrocite, both crystallizing in orthorhombic system, are the most common forms of ironIII oxyhydroxide and the most important mineral carriers of iron in soils. IronIII oxyhydroxide is the main component of other minerals and mineraloids:

Goethite is found as an supergene oxidizing weathering product of many iron minerals. In the near surface, it was an important iron ore mineral developed over banded iron formations. It is found in sedimentary rocks as concretions and was mined from bog ore deposits.

Mineralogy of Martite Goethite iron ore in Australia .

Giant ironore deposits, such as those in the Hamersley Province of northwestern Australia, may contain more than a billion tonnes of almost pure iron oxides and are the world39s major source of iron.

Preliminary dating of martite goethite iron ore in the .

iron oxides were 45 6 Ma or MidEocene for the sample at 163 m 42 5 Ma or MidEocene for the sample at 116 m and 28 3 Ma or Early Oligocene for the sample at 90 m. Key words: Iron Ore, MartiteGoethite, Western Australia, UTh/He Dating.

Iron Geoscience Australia

In the Earth39s crust iron is found mainly as minerals of iron oxide such as hematite, magnetite, goethite and limonite. The minerals that are mostly used as ore for making iron are hematite Fe 2 O 3 and magnetite Fe 3 O 4. Iron is quite soft and easily worked, but it has a very high melting point of 1538C.

Goethite Assignment Point

Goethite is an iron oxyhydroxide containing ferric iron. It is the main component of rust and bog iron ore. Goethites hardness ranges from 5.0 to 5.5 on the Mohs scale, and its specific gravity varies from 3.3 to 4.3. The mineral forms prismatic needlelike crystals needle iron ore, but is more typically massive.

Goethite HyperPhysics Concepts

This goethite sample was formed after pyrite when chemical conditions changed. It retains the pyrite39s basic cubic shape, so it is a pseudomorph. Pyrite is an iron sulfide, and goethite is an iron oxide hydroxide. This compares the goethite sample with a cubic pyrite sample from Ambassaguas mine, Amejun, La Rioja, Spain.

Iron Ore Department for Energy and Mining

From 1915 to 1965 the Iron Monarch and Iron BaronIron Prince mines were the main supply of ore for Australia39s iron and steel industry. The favourable logistics of low cost of ore extraction and the nearby portsite at Whyalla, led BHP to establish an integrated steelworks at Whyalla in 1964.

The binding and reactions of nucleotides and polynucleotides .

The iron oxide hydroxide minerals goethite and akaganite were likely constituents of the sediments present in, for instance, geothermal regions of the primitive earth. They may have adsorbed organics and catalyzed the condensation processes which led to the origins of life. The binding to and reactions of nucleotides and oligonucleotides with these minerals was investigated. The adsorption .

Introduction: goethite is a common weathering product of ironbearing minerals in oxygenated environments and can be an important component of iron ore derived from weathered iron mineralization. Goethite is also a primary precipitate in hydrothermal, marine, and bog environments upon oxidation of reduced ironbearing waters.

Shine Iron Ore Project, Perth, Western Australia, Australia

The iron ore mineralisation at the project area occurs as goethite, hematite and magnetite. While the hematitegoethite mineral resources are located in the upper portions of the BIF, magnetite occurs in the lower portion, approximately 100m below the base of oxidation.

CSMS GEOLOGY POST: GOETHITE FROM THE PIKES PEAK BATHOLITH

The reason my memory was recently jogged about iron oxide minerals is that Mr. Rockhounding the Rockies rockhounding kw.blogspot.com, 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 oxidehydroxide FeOOH.

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.
