Evidence of hypersaline sedimentary environment in Dinantian carbonate deposits in area of Krzeszowice near Kraków
Abstract
Dowody na hipersalinarne środowisko sedymentacji weglanowych utworów dinantu rejonu Krzeszowic koło Krakowa
Pseudomorphs after evaporites and evaporite-solution breccias were found within the Dinantian limestones exposed north of Krzeszowice. Also other indicators of increased water salinity were identified: (a) occurrence of restricted and specific fossil assemblage, (b) presence of crusts of coniatolite and coniatoid types, (c) occurrence of laminated dolomicrites. Sedimentary features indicate back-barrier environment of low energy (lagoon).
