Abstract : The Mössbauer spectra of five tourmalines in the dravite-schorl series at temperatures in the range 4.2K to 600K have been subjected to a systematic fitting procedure. No prior models of numbers of iron sites or their relative occupations were assumed. It was found that a fitting scheme containing four quadrupole doublets was adequate to fit the spectra of all of the samples over the whole temperature range, although the parameters of some of these doublets indicated that they may contain more than one overlapping component. Possible models for the origins of these doublets are briefly discussed.
