Abstract

  Fe<sup>2+</sup>:Fe<sup>3+</sup> ratios of natural fayalite and forsterite were estimated by applying a correlation between Fe<sup>2+</sup>:Fe<sup>3+</sup> ratios and relative intensities of Fe<i>L</i><sub>α</sub> and Fe<i>L</i><sub>β</sub> X-ray emission peaks. These ratios were then compared to those determined by the Mössbauer spectroscopic method to examine the consistency between the two methods. Average Fe<sup>2+</sup>:Fe<sup>3+</sup> ratios of the fayalite and forsterite obtained from the X-ray emission peak intensities were 94(3):6(3) (<i>n</i> = 3) and 90(3):10(3) (<i>n</i> = 3), respectively. These values were close to those determined by Mössbauer analysis: 94(3):6(1) and 94(4):6(1) for fayalite and forsterite, respectively. The X-ray emission peak intensity method is thus useful for the estimation of Fe<sup>3+</sup> content in olivine.<br>
