Limonite forms through the weathering of iron-bearing minerals such as pyrite, magnetite, and hematite under conditions of low temperature and low oxygen. The iron oxide minerals react with water and oxygen in the atmosphere to form hydrated iron oxides, primarily goethite and lepidocrocite. The weathering process can occ…
