Mössbauer spectra of synthetic Ca-Fe pyroxenoids and lunar pyroxferroite
Resolution of the iron sites in the Mössbauer spectra of Ca-Fe pyroxenoids is only partial, two doublets being apparent in each case, whereas there are up to nine cation sites in each structure. Thus the inner and outer doublets represent, respectively: two sites and two sites in Ca0.5Fe0.5SiO3(ferrobustamite); five sites and two sites in Ca0.15Fe0.85SiO3 (pyroxferroite); and five sites and four sites in FeSiO3 (ferrosolite III). Disorder of iron and calcium which exists in the two calcium-bearing pyroxenoids is not readily apparent in the spectra.
