The presented diploma thesis focuses on the examination of physical and physico-chemical properties of soils in the area with the occurrence of limnoquarzites, as a representative of poor chemogenic sedimentary minerals, which were formed by precipitation of silicic acid in hot postmagmatic lakes. The work builds on the theoretical foundations addressed in the bachelor's thesis. In choosen locality, measurements were implemented by non-destructive geophysical methods in order to determine the thickness of the soil cover and the deposition of underlying minerals. We dug a soil probe at that habitat, made a description of the soil profile and took soil samples to determine the bulk density of the soil and the concentration of macroelements. The samples were then measured using appropriate methods and the measured results were evaluated and described.
