| Popis | The studied sections are situated on the northwestern margin of the Vienna Basin. They represent a characteristic marginal facies of Lake Pannon in the late Miocene Pannonian stage. Biofacies as well as lithofacies point to a transgressive event resulting in the shift from deltaic, riverine conditions to the formation of freshwater marshes and lakes and, finally, in the deposition of offshore clays. Biostratigraphically, the logged sequences correspond to the regional Pannonian mollusc zone C. The extraordinarily fine-scaled Paleoecological resolution might serve as a basis for a correlation of 4th order changes reported from basinal settings of the northern Vienna Basin. Thus the rapid facies succession on the northwestern margin of the Vienna Basin is interpreted as being linked to major lake level changes rather than to solely local changes in the riverine system. |
