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