Abstract (in english)
   The gypsum sequence outcropping in an active gypsum quarry in Kobeřice shows many similarities to other sections know from the northern marginal part of the Badenian basin. However, the pecularities of Kobeřice gypsum section indicate its more basinward localiton when compared to other gypsum exposures known from Poland and West Ukraine. The lower part consists of crystalline gypsum (giant gypsum intergrowths, sabre gypsum) accompanied by gypsiferous claystones and microcrystalline gypsum, and the upper part consists of interbedded laminated gypsum, gypsiferous claystones and breccias. These breccias are interpreted as debrites. The laminated gypsum units can be interpreted as fall-out from a low-density turbid layer. The major part of the gypsum sequence of Koběřice originated thus in deeper, density-stratified waters.
   The only exceptions to rather deeper water conditions prevailing during gypsum (and related clystone) deposition are exposure episodes following deposition of giant gypsum intergrowths and during the alabastrization phases. Particular gypsum units are common throughout the quarry, although some distinct lateral changes are observed. Amount of clay material in the facies of giant gypsum intergrowths increase toward the east and this increase is accompanied by change of massive facies to skeletal facies of giant gypsum intergrowths. Also the thickness of laminated gypsum units as well as the number and thickness of breccias in the upper part of gypsum sequence increase toward the east, whereas the frequency of amalgamates of supercones decrease toward the east. These changes observed in the quarry reflect the presence of a paleoslope
