It forms in bogs and marshes (as bog iron ore), in the weathered zones (gossans) above ore deposits, and as a staining agent in soils and sedimentary rocks.
Historically and in some locations today, it is mined as a source of iron ore, though it is generally lower grade than hematite or magnetite ores.
It ranges from yellowish-brown to dark brown, often giving rocks and soils a characteristic rusty colour.
