Examination of Age-Depth Models Through Loess-Paleosol Sections in the Carpathian Basin

The Carpathian Basin holds exceptional significance for Quaternary research, particularly in loess studies. In this study, we attempted to create age-depth models based on age data from scientific journals to investigate accumulation rates. We examined eleven open profile sections for loess and paleosol, including seven in Hungary, two in Croatia, and two in Serbia. We demonstrated that radiocarbon age data are much more useful and reliable than OSL/IRSL data for this type of investigation. The results indicate that the Pécel, Dunaszekcső, Madaras and Katymár sections exhibit accumulation rates an order of magnitude higher than the other sections, exceeding one millimeter per year. These findings suggest that, owing to the basin’s geographic position, these areas were consistently exposed to dust deposition, irrespective of changes in climate or wind direction. A secondary accumulation maximum was also detected along the Katymár–Surduk axis, indicating an additional phase of intensified sediment deposition within this transect. The absence of a young sediment maximum in the Máza section is interpreted as resulting from a shift in prevailing wind direction, which caused the incoming dust to be intercepted by the Mecsek Mountains.
