Environment: Limonite is a secondary material and often accumulates due to its own resistance to weathering. Limonite is formed as a result of ironrich materials like hematite or magnetite weathering (1). Limonite commonly forms as a precipitate around mine entrances, springs, bogs, and other shallow marine areas (1).
