Explanation:

Oxidation of iron to give (various) rusts has been much studied, in that it causes building to fall over (eventually).

#Fe(s) + 1/2O_2(g) rarr FeO(s)#

#2Fe(s) +3/2O_2(g) rarr Fe_2O_3(s)#

#Fe_3O_4#, whose formulation as #Fe_2O_3*FeO# is easier to consider as a mixed oxidation state metal oxide, occurs naturally as the mineral magnetite.
