2010-6-3 · Martite is a psuedomorph of Hematite after Magnetite, not a weathering product. Therefore it is a chemical replacement of the Magnetite by Hematite, produced at depth and under pressure. It may be either a straight replacement process or an oxidation like process, but without depth and pressure the shape and form of the Magnetite would be lost.
