| Description | In the Alpine-Carpathian Foredeep and the Vienna Basin in Austria deposits of the Hollabrun-Mistelbach Foration of the upper Miocene have been studied in 65 outcrops between Krems und Zistersdorf. Two genetically related depositional environment were recognised. The depositional environment of a gravel-bed river is dominant in the majority of the outcrops. Towards the east this sytem developed into a braid-delta environment. Larger scale architectural elements recognised within the gravel-bed river deposits are gravelly chennel fills, sandy channel fills and overbank deposits. The studied deposits of the braid-delta represent the proximal part of the delta and can be subdivided into deposits of distributary channels, mouth bars, gravelly beaches, foreshore and shoreface deposits and interdistributary areas. |
