Paleoenvironmental evolution of Central Paratethys Sea and Lake Pannon during the Cenozoic

Popis výsledku v původním jazyce

Deep wells penetrated Cenozoic sedimentary record of two different basins: 1) Oligocene retro-arc basin which isburied under the 2) Miocene back-arc Danube Basin. This study is focused on biotic and abiotic proxies discussedin terms of existing biostratigraphical, paleoenvironmental and sedimentological data. Biotic proxies are representedby palynofacies and biomarkers (palynomorphs, AOM, phytoclasts, TOC, Pr/Ph ratio, steranes).Abiotic proxies are represented by inorganic geochemistry (e.g., CIA, Sr/Ba, Ga/Rb, Th/U, SiO2/Al2O3, Corg/Pand enrichment factors). The biotic and abiotic proxies helped to refine the knowledge about the changes inredox conditions, salinity, depositional system, and paleoclimate. In the study area five temporally differentenvironments are observed: 1) Sedimentation in the Oligocene fragment of the retro-arc Hungarian PaleogeneBasin that took place on a highly proximal part of the shelf. A major dysoxic event connected with humid marshenvironment is documented within (last Rupelian transgression; Ru4/Ch1–Ch2). 2) After a hiatus the DanubeBasin initiated with early Badenian (Langhian) stable oxic to slightly dysoxic shelf with minor salinity changes(Lan2/Ser1-Ser2 transgression). 3) Late Badenian (early Serravallian) dysoxic deposition, similar in all basins ofthe Central Paratethys, was influenced by upwelling connected with the Ser2-Ser3 transgression. 4) Sarmatian(late Serravallian) dysoxic event associated with subsequent flooding (Ser3-Ser4/Tor1), which created shallowmarginal marine environment. 5) Pannonian (Tortonian-Messinian) sedimentation took place on an oxic shelf ofthe Lake Pannon near a fluvio-deltaic source, most likely represented by the paleo-Danube delta system.
