Correlation of sulphate deposits of the Carpathian Foredeep at the boundary of Poland and Ukraine

Badenian (Middle Miocene) sulphate deposits comprise different lithofacies of primary gypsum, anhydrite and secondary gypsum. Facies and sedimentary studies indicate the gypsum deposits were submitted to burial alteration to anhydrite in several stages of diagenesis. Preservation of primary lithologic features allows the correlation of gypsum and anhydrite sections over a large area of the northeastern Carpathian Foredeep. The facies variety reflects distinct sedimentary conditions in the peripheral part of the evaporite basin. They comprise subaqueous (relatively deep-and shallow-water) as well as subaerial settings.
