Limonite: Mineral information, data and localities.
Currently used as a field-term 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. ...
Limonite – WGNHS – UW–Madison
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 used in the literature. The …

2.2 Mineral Groups Most minerals are made up of a cation (a positively charged ion) or several cations, plus an anion (a negatively charged ion (e.g., S 2−)) or an anion complex (e.g., SO 4 2−). For example, in the mineral hematite (Fe 2 O 3), the cation is Fe 3+ (iron) and the anion is O 2− (oxygen). The two Fe 3+ ions have an overall charge of +6 and …
Limonite: Properties, Characteristics and Uses
Limonite is usually defined as a mineral that is the closest to the correct definition, however it must be clarified that it is not true either and in fact even geologists often say that limonite is a mineral, but no!

Mineral Group: Limonite belongs to the oxide group because it contains a metal (Fe) combined with oxygen, water, or hydroxyl (OH-). And because it can contain water or hydroxyl, it is also placed in the hydroxides subgrup. Environment: Limonite is a secondary material and often accumulates due to its own resistance to weathering. Limonite is ...
