Is the deposition of sediment or rock which contains minerals such as iron ore, Magnetite (Fe3O4), ilmenite (Fe Ti) O, hematite (Fe2O3). siderite (FeCO3), and bog iron or limonite (2Fe2O3.3H2O). Iron ores are rarely present as a native element; examples that Fe is present as an element found in western Greenland, is precipitated with nickel meteoritesIs the deposition of sediment or rock which contains minerals such as iron ore, Magnetite (Fe3O4), ilmenite (Fe Ti) O, hematite (Fe2O3). siderite (FeCO3), and bog iron or limonite (2Fe2O3.3H2O).
