The Bochnia salt deposit is located in front of the Carpathian overthrust, in the area of folded Miocene strata. The tectonic element in which the deposit is situated is called the Bochnia anticline. The structure of the deposit is complicated due to intensive tectonic deformations and different mechanical properties of rocks which build the deposit. Effects of these processes can be observed in mine's workings, where many tectonic mesostructures, such as slickensides, folds with boudinage, tectonic breccias, and systems of fractures in claystone filled with fibrous halite occur. Tectonic mesostructures were measured in accessible mine's workings. The descriptive characteristic of mesostructures was also done. The impact of rocks' mechanical properties on the type and character of deformation was considered as well. On the basis of measurements, authors tried to characterize the direction of tectonic stresses which affected the salt series in the Bochnia area. Authors confirmed the S-N direction of tectonic compression but also indicated SW-NE deviation form the main direction.
