Problem overview
Cross-section of the Jelovica plateau which is represented with the yellow colour on a west part of the poster feature image.
New interpretation of the tectonic structure of the region, Quaternary faults and most important paleostress directions.
• Geological structure of the region between the Kropa village and Kamnik was not sufficiently well understood in the geological literature.
• The region is exceptionally important for the reliable interpretation of the South Alpine Thrust Fault, along which the Southern Alps are thrust upon the Outer Dinarides.
• Detailed geologic mapping of the region.
• Stress and strain analysis of the fault slip-data.
• Interpolation of the paleostress and paleodeformation field of the region.
• Analysis of the digital terrain model, including hillshading and bipolar dif-ferentiation method.
• Finite-element modelling (FEM) of the stress fields in the region.
New structural interpretation of the Sava Fault zone east from Kamnik.
Interpretation of the active Quaternary faults based on the analysis of the digital terrain model with the high fre-quency interpolation.

In the research paper we present a new tectonic and structural interpretation of the South Alpine Thrust Fault in the Central Slovenia, between the Kropa village and Kamnik. The new interpreta-tion is based: (1) on geologic field work and mapping, (2) on the analysis of the digital terrain model of Slovenia and (3) on the numerous microtectonic studies and interpolation of the pale-ostress fields in the geological past of the region.
