3.9.4: Geology- Iron and its Ores
Hematite exists in several phases (denoted &alpha--hematite;, β, &gamma--maghemite; and ε), and they are all different from ordinary rust, which is also often given the formula Fe 2 O 3. Fe 2 O 3 is the chief iron ore used in production of iron metal. FeO is nonstoichiometric.
