Abstract

The Malé Karpaty Mountains in southwestern Slovakia contain more than 650 dolines, mostly arranged along tectonic and lithological boundaries. These dolines serve as important indicators of geological structures and provide valuable insights into the underlying bedrock and rock formations. This study focuses on the spatial distribution and formation processes of dolines in the Malé Karpaty Mts. using advanced methods, such as Digital Terrain Models (DTM) derived from airborne LiDAR data. By combining DTM with field measurements and GIS analysis, the study identifies the tectonic and lithological controls on doline formation and demonstrates their value in interpreting the geological and geomorphological evolution of the area. The results highlight the importance of dolines as markers of subsurface structures and their critical role in understanding karst landscapes.

Key words: dolines, DTM, LiDAR, lithology, Malé Karpaty Mts., tectonics, Western Carpathians
