Supraregional (palaeo)geoecological studies require detailed knowledge of the distribution
of aeolian sediments and their sources. Such spatial data can be visualised and shared
in maps, but often these are constrained in their resolution or extent. This is the
case for the Carpathian Basin, where cross-border maps are not detailed enough to
answer many research questions. Problems occur especially along political borders
due to different geological mapping standards and varying lithological definitions.
Using a Geographic Information System (GIS), we compiled a map showing the distribution
of loess and related Quaternary sediments in the Carpathian Basin, with unprecedented
detail. We vectorised and analysed existing data (mainly from geological maps) and
combined and transferred these into a common (loess) sediment classification system.
This cross-border map shows the distribution of aeolian sediments in the Carpathian
Basin at a scale of 1:1,500,000. For the northwestern and the southern Carpathian
Basin, we added maps that clarify the extent of late Pleistocene and Holocene terrace
and floodplain deposits, which were merged in the to highlight the predominant dust
source areas for this region.
