Is that goethite is mineral an iron oxyhydroxide that is the main constituent of rust while limonite is mineralogy any of several natural hydrous iron oxides often a mixture of goethite and hemite with clays and manganese oxide.

Much Limonite especially the fibrous type is either Goethite or alter ed Goethite that absorbed water in its chemical structure. Limonite commonly forms as a pseudomorph over other minerals especially Pyrite Marcasite and Siderite. These pseudomorphs are very identifiable by

Limonite is commonly associated in its occurrence with hematite turgite pyrolusite calcite siderite etc. Identification and Diagnostics In its chemical properties limonite resembles goethite from which it can be distinguished only with great difficulty except when the latter is in crystals.

The Mineral goethite 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 and160velvety160 botryoidal growths.

It precipitates directly from marine and meteoric waters and is the main mineral phase containing precipitated iron in these environments. It may form mixtures with other similar minerals which may alter the color. Limonite is a mixture of several iron oxides and hydroxides goethite usually being one of the most important constituents.

Uses. Goethite is used as an ore of iron but in the trade it is classed with limonite as brown hematite. Use In some localities it is an important ore of iron. Return to the Mineral Collectors Information Page

The term quotlimonitequot is not the species name of the mineral but it is usually the general term for goethite and water goethite. Because these mineral particles are small and difficult to distinguish they are collectively called quotlimonitequot. Limonite is one of the main iron minerals.

Goethite is a hydrated iron oxide mineral and forms in hydrothermal deposits and is a common constituent of soil. Deep black radiating Goethite needle like crystals and massive iridescent stalactitic forms make fine specimens for collectors. Goethite is often found included within Quart.

As the content of limonite in gravel was found to be significantly higher in gravel than in sand even if samples were collected closely together at the same site it must be deduced that the higher porosity of gravel plays a role which implies that mineral alteration into limonite

Iron hematite magnetite and goethite. The predominant minerals in DSO are usually the ferric iron oxides hematite Fe 2 O 3 goethite FeOOH andor limonite FeOOH.nH 2 O By comparison magnetite ore typically has a much lower iron content when mined of between 25 and 40 Fe and in this form is unsuitable for steel making.

Limonite is not a true mineral but a mixture of similar hydrated iron oxide minerals. Most of limonite is made up of Goethite. Massive Goethite and Limonite can be indistinguishable. Limonite forms mostly in or near oxidied iron and other metal ore deposits and as sedimentary beds. Limonite has been known to pseudomorph other minerals such as

It often contains significant amounts of iron oxide minerals such as goethite and hematite. This research revealed that the material called quotlimonitequot does not meet the definition of a mineral. Instead limonite is a mineraloid composed mainly of hydrous iron oxides that are often found in intimate associations with iron minerals.
