Mn 2 is 0.83 and Fe 2 is 0.78 197, while the 3 ions are 0.70 and 0.65 197. Accordingly, Mn is commonly found substituted in small amounts in Fe minerals. Mn, however, also has access to a higher valence state, 4, which gives rise to a plethora of complex Mn oxide minerals that do not have Fe counterparts.
