Geochemie půd vázaných na výskyt těšínitů

Abstract

The bachelor thesis is devoted to determination of geochemical background of soils, which are influenced by presence of rock teschenite association. The geochemical study of rock was oriented to determination of concentration of trace and main rock forming elements in teschenites, picrties, monchiquites and fourchites. The geochemical background value was determined for individual petrographic rocky type and also for all rocks from teschenite association. For determination of geochemical background for soils the area of Rybi ate Nový Jičín was chosen. The geochemical background was calculated with different approach, which differ with access to the anomalous values. From the value for geochemical background it appears, that the forest soils contain higher concentration of Pb and As, which antropogenous orign (long-distanc transfer).
