Palynostratigraphy and palynofacies of the Permian-Triassic transitional sequence in the Żary Pericline (SW Poland)

Abstract

One spore-pollen assemblage representing the Lundbladipora obsoleta-Protohaploxypinus pantii Zone was recognized within the lowermost Buntsandstein deposits in the Żary Pericline. For the first time possible fresh water algae were found in Early Triassic sediments of Poland. Moreover, four palynofacies were distinguished, which together with sedimentological features of the studied deposits, indicate deposition in a playa environment. The palaeoclimatic model used in this study shows warm (tropical) dry climate during the Early Triassic in SW Poland.
