Cretaceous biostratigraphy and lithostratigraphy of the Glinzendorf Syncline based on well Gänserndorf UeT3 (Vienna Basin, Austria)

Abstract The 2200 m thick Cretaceous units of well Gänserndorf UeT3 have been biostratigraphically analyzed based on cuttings from 3210 to 5140 m. deposits the Tirolic Glinzendorf Syncline (a part buried Northern Calcareous Alps) can be largely correlated with Lower Gosau Subgroup Grünbach Syncline. An exception is basal unit, which has no equivalent in This lower unit subdivided into a non-marine and marine upper part. No age constraints are available for part, whereas possible range middle Turonian Coniacian. For this documented first time Syncline, we propose Formation as new lithostratigraphic term. Fm. overlain by Fm., intercalated conglomerates. These interpreted equivalents Dreistetten Conglomerate Mb. calcareous nannofossils these suggest latest Santonian early Campanian age. Non-marine conditions prevailed during deposition but incursions indicated parts top formed an about 50-m-thick coal, rich Characeae oogonia, which, together conglomerates serve marker layer correlation outcrops marls silty shales Piesting late Maastrichtian documented. Marine predominated interval. topmost overthrusted represents sandstones Thrust detected constrained time.
