Description :
The Medves Region is one of the landscapes units of North Hungary, is mainly a hilly land and has variegated geological formations above all from the Oligocene-Miocene epochs. Rhyolite tuffs (Gyulakeszi Rhyolite Tuff Formation) dated from the beginning of the Ottnagien age are very typical at this area. These „tuffs” are mainly ignimbrites and came into being due to heavy but episodic, 2-4 times repeated successive volcanic eruptions. The barren rhyolite tuff surfaces are optimal for the study of erosional processes. This review attempts to describe the processes active on the surface and the forms produced by them. - (AM)
