• Limonite is scientifically not considered a true mineral as it lacks a definitive chemical formula and crystal structure. However, all mineral reference guides list it together with other minerals. Limonite is extremely common and forms the coloring matter in many soils. It is also responsible for the coloring on the weathered surfaces of rocks. Much Limonite, especially the fibrous type, is either Goethite or altered Goethite that absorbed water in its chemical structure.
• Chemical Composition: FeO(OH) · nH2O; Hardness: 4 - 5.5; Color; Yellow, brown, reddish-brown. Occasionally iridescent in a play of colors;
• Limonite usually occurs as a secondary material, formed from the weathering of hematite, magnetite, pyrite, and other iron-bearing materials. Limonite is often stalactitic, reniform, botryoidal, or mammillary in habit rather than crystalline. It also occurs as pseudomorphs and coatings on the walls of fractures and cavities.
