Cím:Aeolian surface transformations on the alluvial fan of the Nyírség / Lóki József, Négyesi Gábor, Buró Botond, Félegyházi Enikő
Megjegyzések:The evolution of the Nyírség and its landforms has been widely addressed by Hungarian geographers and geologists in the past and atpresent as well. Early works were mainly concentrating on understanding the complex, fluvial and aeolian genetics of the territory, later morespecific forms and problems were studied and revealed. By the increasing number of chronological evidence derived from stratigraphic,pollen and archaeological data and absolute dating techniques (radiocarbon and optically stimulated luminescence) the geomorphologicaldevelopment can be reconstructed in more detail, especially in thecontext of climate variations and human intervention. Our study aimsto summarize and outline the times of aeolian activity, with specialrespect to Holocene events, on the basis of the researches carried out sofar. By nowadays it is obvious that sand was moving on several occasions in the Nyírség during the Holocene subsequent to the mainaeolian land formation periods of the Upper Pleniglacial and the lateglacial. In the first half of the Holocene sand movement can be relatedto dry periods, thus aeolian activity was driven mostly by climaticfactors. In the second half of the Holocene the area of land affected bywind erosion decreased and in most cases events can be associated tothe activity of man. Nevertheless, climatic and anthropogenic factorscould be superimposed, leading to significant local sand mobilisation.
