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)Fe(s)+12O2(g)FeO(s)

2Fe(s) +3/2O_2(g) rarr Fe_2O_3(s)2Fe(s)+32O2(g)Fe2O3(s)

Fe_3O_4Fe3O4, whose formulation as Fe_2O_3*FeOFe2O3FeO is easier to consider as a mixed oxidation state metal oxide, occurs naturally as the mineral magnetite.
