摘要
Objective Magnetite occurs widely from hydrothermal to magmatic rocks, which has inverse spinel structure. As known for long time, it carries some foreign matters, such as A1 and Ti, even silicon. Silicon and iron are quite different, either from the ionic radii or electronic obtain ability. However, both electron microprobe data and wet chemical methods analysis show that magnetite contains certain amount of silicon. Whether the silicon is similar to AI, Mg and Ti, entering into the magnetite lattice, is not clear. In addition, isomorphism would occur in both tetrahedron and octahedron in magnetite,
