Sažetak
Six pedological profileswere analyzed above five typical lithological units inMedvednicaMountain to determine the effect of eolian additions to the soil composition, as well as the possible influence of relief, vegetation cover, and anthropogenic input on the dynamics of pedogenesis. Bedrock composition was defined using petrographic (thin sections) and chemical analyses (major and trace element contents), whereas pedological, sedimentological and geochemical characteristics of six cross-sectionswere determined by chemical (major and trace element contents), mineralogical (modal analysis), and grain size analysis. Soils developed on sedimentary bedrock (Mollic Rendzic Leptosols (Calcaric) and Albic Luvisol (Sceletic))mostly originate fromweathering of siliciclastic detritus that was exposed to oxidization before diagenesis. Furthermore, soils on metasiltstone, marble and Lithothamnium limestone exhibit similar modal and geochemical composition and element distribution across the soil profile. In contrast, soils developed on igneous bedrock originate mostly from weathering of minerals of the first weathering cycle and thus abound with chemically less resistant minerals and less mobile elements. However, all profiles contain higher concentrations of lead with respect to bedrock indicating airborne contamination.
