Geology

Short characteristics of the site: Bohemian Cretaceous Basin, so called Jizera development. Veselka water flow beach exhibits the uppermost parts of the Jizera Formation consisting of calcareous sandsones with some carbonate concretions as much as several tens of centimetres large. This type of sandstones is typical for top parts of cuestas in the Rovensko area. On the opposite flow bank Pleistocene outflow fan can be observed with melaphyre clasts. Earlier, garnet graines were washed from this material.
