Magnetite has been important in understanding the conditions under which rocks form. Magnetite reacts with oxygen to produce hematite, and the mineral pair forms a buffer that can control how oxidizing its environment is (the oxygen fugacity). This buffer is known as the hematite-magnetite or HM buffer. See more Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe Fe 2O4. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. … See more Biomagnetism is usually related to the presence of biogenic crystals of magnetite, which occur widely in organisms.
