    Transformation of magnetite to hematite and its influence

    The dissolution of magnetite seems to be related to its transformation to hematite by oxidation of Fe 2+ to Fe 3+. The transformation of magnetite to hematite occurs along {111} planes, and results in the development of hematite domains along {111} that are parallel to the foliation.
