Pielach Formation (Austria)

The Pielach Formation is a geologic formation in Lower Austria, Austria. It preserves fossils dating back to the Chattian stage (late Kiscellian to early Egerian) of the Oligocene period. The formation unconformably overlies basement rock, and is overlain by the Melk Formation.
