AUTOCHTHONOUS SALT SERIES IN THE MIOCENE OF THE SUB-CARPATIIIAN AREA, WEST OF WIELICZKA

In the area between Cracow, Wieliczka and Sidzina, the Tortonian deposits crop out or occur under a thin cover of Quaternary formations. The youngest Tortonian formations are developed as the Bogucice sands and sand stones (Grabovian). The Lower Tortonian (Opolian), however, consists of days and arenaceous clay slates·among which a salt series (series of evaporites) has·been laid·down. The southeastern part of the area considered belongs to the zone of "allochthonous" Miocene, raked together and folded up in·front of the Carpathian flysch moving from the south. Here occur known for a long time and exploited rock salt deposits at Wieliczka and Barycz. North and west of the deposits mentioned above, an autochthonous Miocene salt series occurs slightly disturbed in the zone horde ring on the "allochthonous" salt series overthrusted from south. The autochthonous salt series is built up of a clay complex containing gypsum and ,anhydrite. In the vicinity of Swoszowice, there are found sulphur-bearing gypsums and marls. Only in a small area, between Barycz and Krzyszkowice, deposits of increased degree of chemical sedimentation occur as rock salts with gypsum and anhydrite. Due to examination of continuity of the allochthonous salt series between Wieliczka and Sidzina it was possible to confirm that the clays with gypsum, the sulphur-bearing coals and' the rock salts with anhydrite represent one horizon of chemical deposits in the area under study.
