Is hematite igneous rock
WebMagnetite is a rock composed of iron ores and is naturally ferromagnetic. It is believed to attract magnets and has the potential to form a permanent magnet. The rock contains various types of sedimentary, metamorphic, and igneous rocks. Magnetite is found in mountain caves adjacent to the lost river and the jellyshroom cave. Granite 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…
