Remnants of Paleogene palaeosurface in the surroundings of Pěnkavčí Hill in Lužice Mts., northern Bohemia
Abstract
The sub-rounded to rounded clasts of silicified sandstones, quartzites and less frequently also ferruginous sandstones were found at different altitudes in the surroundings of Pěnkavčí Hill in Lužice Mts. They were rounded by the function of long exposition on the surface rather than by an active transport and represent a remnant cover of a Paleogene palaeosurface, most probably of a pediplain. This planation surface predates the morphogenetic phase connected with the intrusion of neovolcanites dated from Upper Eocene to Pliocene. Therefore the most probable chronostratigraphic age of the pediplain cover is Eocene. However, more accurate dates of neovolcanic rocks are required for better chronostratigraphical setting of that palaeosurface.
