Abstract

Room temperature Mossbauer spectroscopic measurements of 23 natural and 12 synthetic staurolite samples, the latter representing both Fe-Mg and Fe-Li solutions, demonstrate that the majority of the Fe in all samples is Fe2+ which occupies the Fe1, Fe2, and Fe3 subsites of the tetrahedral Fe site in an average ratio of 43/12/27. Mossbauer parameters of the various sites do not vary systematically with composition and appear to be independent of next nearest neighbor effects (except in the case of H). These results corroborate previous structure refinement data on the existence of three major Fe subsites and provide direct evidence of minor Fe occupancy in the octahedral sites. -from Authors
