Other Site Characteristics

This loess valley developed in the middle region of the plain of Mezofld, directly touching the downtown district of the town Szkesfehrvr. From the geological aspect, the site belongs to the northest extension of the loess ridges of Mezofld. In the Pannonic Age, thick marine sediment (sandy, clayey, marly) was deposited and dryed out with the retreat of the sea. In the Lower Pleistocene, as a result of tectonic movements the united table land was divided in the north-south, northwest-southeast direction and was lifted slightly. The dry surfaces provided excellent conditions for the development of loess, most intensively in the Upper Pleistocene. As for the geomorphology of the region, it is characterized by the stream valley cut into the plain terrain in the northwest-southeast direction. From the botanical aspect, the region belongs to the Alfld (Great Hungarian Plain). In the evolution of the flora of the area loess played an essential role. The predominant potential habitat of Mezofld is Aceri tatarico-Quercetum and in a smaller proportion loess grasslands as well as steppe woodlands.
