Abstract

The transformation mechanism of Fe (super 2+) cations in two samples of natural olivine (Fe,Mg) (sub 2) SiO (sub 4) after heat treatment in air in the temperature range 400-1180 degrees C has been studied using (super 57) Fe Mossbauer spectroscopy and XRD measurements. The influence of heating duration (from one to 96 hr) on the behavior of Fe (super 2+) ions in the olivine structure was investigated. Fe (super 3+) ions dominate as a primary product of the thermal treatment in air above 1000 degrees C. Heating at 1180 degrees C led to decomposition of the olivine structure. The formation of ferriolivine as a result of low-temperature oxidation was also observed.
