A simple microstructural X-ray diffraction analysis using the Voigt function method reveals differences between bauxite deposits in the Iberian Range - Catalanides area (NE, Spain). The highest values of apparent crystallite sizes, measured by volume weighted Dv values from 001 kaolinite reflection, have been found in bauxites of type 1.
