Hematite | Common Minerals
Regardless of its setting, hematite is usually found with other iron-bearing minerals, especially magnetite, goethite and siderite. In Early Proterozoic (2.5 to 1.6 billion year ago) iron ore deposits, layers of hematite and other iron oxides alternate with bands of chert (microcrystalline quartz) to form distinctively layered deposits known as ...
