Biostratigraphy and paleoecology of the upper Badenian carbonate and siliciclastic nearshore facies in the Vienna Basin (Slovakia)
This study provides a comprehensive examination of algal bioherm structures, including reefs and carpets that contain nannoplankton and foraminifera, originating from the upper Badenian (middle Miocene) strata of the Vienna Basin in the Central Paratethys. These lithofacies primarily consist of the carbonate red algal genus Lithothamnion. Through an integrated approach that combines calcareous nannoplankton, foraminifera, sedimentology, and palynology, the study explores the Serravallian (upper Badenian) sediments from the Vienna Basin. The biostratigraphic age, consistent with the NN6 and CPN9 zones, is further corroborated by 87Sr/86Sr dating. This research highlights the importance of taphonomic processes and paleoecological proxies in small-scale characterization and detecting short-term shifts within paleoenvironmental conditions. These unique bioherm structures enable a novel description of a limestone formation within the Vienna Basin (Sandberg Formation), which seems pervasive across the Central Paratethys region. The findings uphold the hypothesis of a profound connection between the Mediterranean and Central Paratethys via the Trans-Tethyan Trench Corridor, bolstered by upwelling conditions observed in the eastern perimeter of the Vienna Basin. Two main inhibitory mechanisms for carbonate growth in the Upper Badenian within the Central Paratethys area are confirmed: the first is a substantial siliciclastic influx from the Alps and Carpathians, supported by the ongoing rifting of the Vienna and Danube Basins; the second is the propagation of evaporites in the Transcarpathian and Transylvanian Basins leading to precipitation, which disrupts carbonate growth. This investigation underlines the intertwined relationship between regional geodynamics and carbonate sedimentation processes during the Miocene.
期刊介绍:
The journal is open to papers dealing with the interpretation of ancient and modern biotopes and carbonate depositional environments by means of facies analysis in its broadest sense. Once the central part of research in hydrocarbon exploration, facies analysis more and more integrates modern and ancient biogeological processes of a changing earth. Special emphasis is laid on paleobiology and -ecology, basin evolution, sedimentology including diagenesis and geochemistry, as well as studies emphasising the impact of life on earth history. The main part of the target group will be people in academia.
