Siderite is a mineral composed of iron(II) carbonate (FeCO 3). Its name comes from the Ancient Greek word σίδηρος (sídēros), meaning "iron". A valuable iron ore, it consists of

In addition to igneous rocks, magnetite also occurs in sedimentary rocks, including banded iron formations and in lake and marine sediments as both detrital grains and as magnetofossils. Magnetite nanoparticles are also thought to form in soils, where they probably oxidize rapidly to maghemite. The chemical composition of magnetite is Fe (Fe )2(O )4. This indicates that magnetite contain
