Oxide - Wikipedia

In dry oxygen, iron readily forms iron(II) oxide, but the formation of the hydrated ferric oxides, Fe 2 O 3−x (OH) 2x, that mainly comprise rust, typically requires oxygen and water. Free oxygen production by photosynthetic bacteria some 3.5 billion years ago precipitated iron out of solution in the oceans as Fe 2 O 3 in the economically important iron ore hematite.
