Iron (I) oxide (Fe ₂ O) is a pressurized conditions, such as at the earth's surface , in the Earth's crust and in the mantle prevail, unstable iron - oxygen - compound . It therefore does not occur in nature that can be reached by humans. It is believed to be part of the Earth's core as well as the core of the other terrestrial planets in the solar system . Under the enormous pressure deep inside the planet, it should be made of iron (II) oxide ( wustite ) according to the reaction equation

{\ displaystyle \ mathrm {FeO + Fe \ rightarrow Fe_ {2} O}}

arise because under these conditions it is the compound that is more stable towards iron (II) oxide.

This thesis was put forward in 1971 by the Russian geoscientist Oleg Sorochtin and subsequently further developed by the Australian seismologist Keith Edward Bullen .
