The Relation of The South-Eastern Börzsöny Hills to the Visegrad Gorge, Hungary

The Visegrad Gorge of the Danube evolved around the Plio-Pleistocene boundary. The Danube became the absolute base level of the streams in the south-eastern Borzsony Hills. The tributaries of the Danube dissected the previous ancient surface creating geomorphological levels which correlate with the fluvial terraces of the Danube. Based on the determination of the dissected, ancient surfaces and other relict landforms of the south-eastern Borzsony Hills, correlations were carried out between the evolutionary stages of the surfaces above and the fluvial terraces of Visegrad Gorge. To get relevant information, GIS methods, statistical, sediment and geomorphologic analysis were applied. The fluvial origin of the terraces situtated at higher altitudes of the Visegrad Gorge is doubtful. The results of this study comfirmed that the terrace are the remnants of an ancient relief which evolved before the Plio-Pleistocene boundary.
