COMPARISON OF THE MINERALOGICAL COMPOSITION OF THE CLAY FRACTION OF SOILS DEVELOPED ON DIFFERENT PARENT ROCKS

Rok, strany: 1994, 41 - 44

Samples for the comparative study were taken from the Ziar Basin and Kosice Basin. They represent soil horizons A, B, C, D. The basic substrata of the soils are volcanites and Neogene sediments. On the basis of X-ray diffraction, we found differences in the mineralogical composition of the clay fraction of the soils studied. These differences appeared above all in the presence of vermiculite or chlorite-vermiculite, which was identified as the dominant clay mineral in horizon A of two profiles on volcanite rocks. Smectite is dominant in the lower horizons of these soils. Illite, chlorite, kaolinite and illite/smectite are the other identified minerals. Smectite or illite/smectite is the dominant mineral in the clay fraction of the soils developed on underlying Neogene sediments.
