In sedimentary rocks, hematite can either have formed from have originally formed directly from direct precipitation out of marine waters, or as a concentration and enrichment deposit formed from groundwater. Regardless of its setting, hematite is usually found with other iron-bearing minerals, especially magnetite, goethite and siderite.
