Limonite: Mineral information, data and localities.

While "limonite" is poorly crystallized, a number of minerals are noted for decomposing to it without losing their crystal shape particularly pyrite and siderite crystals. Any "crystals" of "limonite" are actually pseudomorphs of other minerals which have decomposed in this fashion.

Limonite | mineral |

The name limonite properly should be restricted to impure hydrated iron oxide (with variable water content) that is colloidal, or amorphous, in character. Often brown and earthy, it is formed by alteration of other iron minerals, such as the hydration of hematite or the oxidation and hydration of siderite or pyrite.
