Our group would like to make the first step to interconnect the Late Pleistocene and Holocene terrace systems in Slovak and Hungarian river valleys, on the study area. We would like to summarize the existing information of regional geomorphological evolution, reconstruct palaeoenvironment near by Mouth of Hron influenced by different facies in the margin of fluvial-alluvial (Palaeo-Hron and Danube) and proluvial (south west pediment of Burda Hills and Kamence) area and the environments affected by the climate fluctuation of Late Pleistocene. It can be expand the knowledge of natural sciences of V4 countries.
