WebJan 1, 2013 · Magnetite is a mix of iron (II, III) oxide, Fe 3 O 4, and is one of the principal magnetic iron ores. Known since antiquity, magnetite was believed to have a purely inorganic origin resulting from magmatic or metamorphic events. WebMagnetite, of magmatic origin, frequently contains exsolution lamellae of ilmentite, which can impede its conductivity. Occasionally, magnetite may exhibit a bladed crystal habit, which would favour an anisotropic conductivity higher than magnetite’s normal euhedral/subhedral occurrence. Increasing tectonism and magnetite grain size can
