In 2007, sampling of cave fill for palaeomagnetic analysis was performed in several caves in the Classical Karst (SW Slovenia). Standard palaeomagnetic analyses were used (thermal and alternating field demagnetisation, magnetic susceptibility measurements, etc.). Paleomagnetic parameters (inclination, declination) indicate that the respective tectonic block has rotated since the deposition of karst sediments (Tabs. 1 to 3). The rotation differs in different time intervals of the infilling of cave passages and in different karst areas. Repeated sampling in some profiles, especially Divaška jama, Trhlovca, Markov Spodmol, confirmed that only high-resolution approach can ensure reliable results.
