Abstract: The study of clay soils using photoacoustic spectroscopy was presented. The observation of the photoacoustic spectra showed the transition bands associated with Fe3+ ions in octahedral or tetrahedral symmetry. Rietveld refinements showed that the Al3+ cations were partially substituted by the Fe3+ cations in the octahedral states of kaolinite structure.
