This grades upward into an oxide facies with abundant coarse-grained hematite andor magnetite and sugary-textured quartz middle iron formation. These Fe-oxide-rich beds are the most important economically, with iron-rich layers and lenses commonly containing more than 50 hematite and magnetite. The upper part of the Soko-Hematite is formed by oxidation of magnetite which is a relatively slow reaction compared to formation of wustite and magnetite at 850 C. If crushing of the oxide scale is incomplete then large flakes with hematite on the surface will result in a positive bias in the XRD hematite signal.
