Magnetite - Wikipedia

Properties. 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.. Crystal structure. The chemical composition of magnetite is Fe 2+ (Fe 3+) 2
