Mössbauer parameters are reported for a number of silicates of known crystal structure, containing high-spin iron in a range of co-ordination symmetries. The spectra are fitted by computer to Lorentzian line shapes and the component peaks in each spectrum are assigned to the various positions in the particular silicate structure. The results show that the chemical shift and the quadrupole splitting to structural features feature for the six-co-ordinate Fe2+ species. Line broadening in such iron compounds is discussed.
