About Limonite
Lustre:
Earthy
Name:
Named in 1813 by Johann Friedrich Ludwig Hausmann from the Greek λειμών for meadow alluding to its common occurrences in bogs.
A Mixture Of:
Used as a field-term for unidentified massive hydroxides and oxides of iron, with no visible crystals, and a yellow-brown streak. 'Limonite' is most commonly the mineral species goethite, but can also consist of varying proportions of lepidocrocite, hematite and/or maghemite, along with impurities of other minerals such as quartz and clays.
Other iron minerals such as hisingerite, pitticite and jarosite group species can also be easily mistaken for an iron oxide coating/replacement, and varlamoffite is a similar yellow-brown crust composed primarily of tin oxide (cassiterite).

Varieties of Limonite
| Adlerstein | Nodular concretions of iron oxides/hydroxides, mainly goethite and/or lepidocrocite, around a core of clay minerals. German word literally meaning 'eagle stone'. |
| Alumolimonite | Al-bearing Limonite |
| Avasite | Probably a siliceous limonite. Reported formula is very doubtful. |
| Bean Ore | A local name for a lenticular (bean-shaped) aggregated limonite. |
| Chromium-bearing Limonite | A chromium-bearing variety of limonite. |
| Exotic limonite | Limonite precipitated in rock that did not formerly contain any iron-bearing sulfide. Compare with indigenous limonite. |
| Gold-bearing Limonite | A gold-bearing variety of limonite. Common in gossans of gold deposits. |
| Indigenous limonite | Sulfide-derived limonite that remains fixed at the site of the parent sulfide, often as boxworks or other encrustation. Compare with: exotic limonite, relief limonite. Ref: AGI |
| Liminitogelite | |
| Limnite | Recently formed varieties of limonite (bog ore) containing much water |
| Stilpnosiderite | A colloidal form of Limonite |
