Abstract: The primary objective of the research was to identify geological structures within the mélange belt and determine whether the carbonate rock outcrops visible at the surface are olistoliths. The study was carried out along a 1-km profile that crossed the mélange zone perpendicularly. Three geophysical methods (gravity, geoelectric and seismic) were applied to solve the problem. Each of these methods follows different physical properties of rocks; therefore, the results should complement each other, although they may not always be fully compatible. The results obtained from all methods allowed the identification of zones with varying physical properties, which can be associated with known geological formations. As described above, each method also detected changes in physical properties within the mélange zone, caused by lime rock outcrops. An integrated analysis of the results of all three methods revealed a very high correlation in the boundaries of the identified zones, significantly validating the final geological interpretation. The findings also confirmed that the rock outcrops observed at the surface are in fact olistoliths embedded in a matrix, much like “raisins in a cake”.
