Research Abstract

Uncertainty in the oxidation state of iron in pyroxene leads to significant uncertainties in estimating the temperature of the inner earth. Oxygen is the only anion in pyroxene and assuming electrical balance, accurate measurements of cation contents allow the iron oxidation ratio to be estimated. Oxygen measurements using EPMA were optimized by examining the analyzing crystal, sample surface, ways of identifying the background, and appropriate correction factors. We are now able to determine the weight percentage of oxygen to within one percent.
