F-riebeckite has been subjected to analysis by 57-Fe Moessbauer spectroscopy from 4. 2K to 501K. The spectra obtained above the magnetic transition temperature, were analyzed in terms of three ferrous doublets in M1, M3 and M2 sites and two ferric doublets occupying M2 and M1 sites. The ratios of these occupations, together with their quadrupole splittings, were then used to fit the 4.2K magnetic spectrum.
