Geologic Occurrence. 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.
