The study is focused on the comparison of mineral composition of different soil types formed on loess. The soil types were classified according to the World reference base for soil resources. Samples were collected from individual soil horizons. Basic soil properties such as the particle-size distribution, pH values, CaCO3 contents, base saturation, cation exchange capacity, soil organic carbon and nitrogen were analysed using routine pedological methods. Mineral composition was evaluated on the basis of XRD analyses of the fraction < 0.001 mm. Semiquantitative mineral composition was calculated from the areas of basal peaks. The studied soils were found to be dominated by quartz, kaolinite and illite. Semiquantitative analyses of mineral composition of the Greyic Phaeozem, Haplic Chernozem and Haplic Luvisol revealed differences in the association and proportion of individual minerals.
