La limonite (également appelée aétite ou pierre à grelots) est un amas d'hydroxydes de fer microcristallin. Elle est également appelée « pierre d'aigle », car autrefois on croyait que les aigles portaient cette pierre dans leur nid pour faciliter la ponte.
limonite, one of the major iron minerals, hydrated ferric oxide (FeO(OH)· n H 2 O). It was originally considered one of a series of such oxides; later it was thought to be the amorphous equivalent of goethite and lepidocrocite, but X-ray studies have shown that most so-called limonite is actually goethite.. The name limonite properly should be restricted to impure hydrated iron oxide (with ...
Limonite. Limonite is actually a group name for the hydrated ferric oxide minerals (Fe2O3H2O), which occur so commonly in many types of rocks. From: Groundwater Remediation and Treatment Technologies, 1997. Download as PDF.

THE MINERAL LIMONITE 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 oxidized iron and other metal ore deposits, and as sedimentary beds.

Limonite is a natural earth containing clay tinted by hydrated iron oxide and traces of calcium sulfate (gypsum) or calcium carbonate (chalk). Limonite is a general term used to describe all forms of hydrated iron oxide minerals (FeOOH) that occur as natural clay or earth. Limonite includes the minerals goethite, akaganeite and lepidocrocite.
Formula: Mixture of hydrated iron oxides Description: Limonite is a general term for a mixture of fine-grained iron oxides, generally dominated by goethite, but also possibly containing hematite, lepidochrocite and other minerals. It forms from the weathering of other iron minerals, and may be precipitated by iron rich surface or ground water. It is a useful field term, and has been frequently ...
Limonite is a very common mineral and can be found throughout the world, with major deposits located in Austria, France, Australia, the United States, Brazil, and the ancient island of Cyprus.
