Contribution to the Fe<sub>2</sub>O<sub>3</sub>/FeO determination in basaltic rocks
Abstract
The relationship between the oxidation state of iron and the fO2 as a function of temperature has been used to determine the Fe2O3/FeO ratio in basaltic rocks as follows: log (FeO/Fe2O3) = 56419 (‒log fO2)‒5.44.
