The study addresses the geomorphological mapping of Quaternary slope deposits in the Skrilje area of the Vipava Valley, SW Slovenia. The aim of the research was to examine the spatial distribution of sediments and geomorphological features, and to identify the relationships between lithological composition, tectonic structure, and slope dynamics.
The methodological approach included a review of existing geological and geomorphological studies, analysis of lidar data, and detailed field mapping using digital tools (FieldMove and QGIS). Lithostratigraphic units (limestone, flysch, scree, and carbonate breccia) were documented in the field and geomorphological features such as calciturbidite megabeds, scree deposit (talus slopes), landslide deposits, and gravitational carbonate blocks were identified.
The results show that the overthrust of carbonates onto flysch creates a distinct lithological boundary that controls sediment displacement. The flysch bedrock represents a sliding surface for scree accumulations and large carbonate blocks. Several phases of gravitational movements were recognized, including rotational and translational slides, further enhanced by intense weathering and hydrogeological conditions.
The study concludes that the geomorphological structure of the Skrilje area is the result of a close interplay of tectonic, lithological, and hydrogeological factors, which together determine the complex dynamics of the Quaternary slope deposits.
