Mossbauer spectroscopy has been used to study iron in clay and related minerals at room temperature. The investigated minerals are kaolinite, montmorillonite, beidellite, bentonite, muscovite, illite, vermiculite, hectorite, biotite and chlorite and, in all, 19 different minerals have been studied. It is shown that iron occupies the octahedral positions and in rare cases also the tetrahedral position. The Fe3+/Fe2+ ratios are determined and compared with the results of chemical analyses. The role of iron impurities in the analyses of the spectra is also discussed, and a search scheme for Mossbauer investigations of clay minerals is given.
