Palaeomagnetic method (magnetostratigraphy) was applied to date four profiles of cave fill in the Classical Karst of Slovenia - Divaška jama, Trhlovca Cave, Divača profile at highway near village of Divača and Černotiče profile in a quarry near village of Črni Kal. The dynamic character of cave filling, and exhumation and fossilisation processes is expressed by numerous unconformities within profiles belonging to inner-cave facies. Brunhes/Matuyama boundary and Jaramillo subchron were interpreted in Trhlovca Cave and Divaška jama. Obtained magnetozones in Divača profile and Černotiče Quarry can be correlated with events within Matuyama up to Gilbert chrons. Therefore, the correlation of obtained arrangements of normal and reverse polarised magnetozones with standard palaeomagnetic scales can be finish only with difficulties and with a high degree of uncertainty as breaks in deposition can hidden a substantial part of the geological time. Without the help of other dating methods, especially biostratigraphy, and correlation of magnetostratigraphic results cannot be explicit.
