Why does my komatiite samples show low Fe2O3 content?

11 August 2015 1 8K Report

The whole rock analysis show positive correlations of FeO, SiO2 with MgO. CaO show negative correlation with MgO. Few samples show early Fe-Ti oxides. CaO is highly variable. Komatiite are associated with pyroxenite intrusives (cumulus). Does it mean that olivine in equilibrium should show high FeO relative to MgO? what is its significance?

Nibin Tom

The components were analyzed by XRF. Fe2+/Total Fe of the samples is varying from 0.62 - 0.76 for the samples.
