Biostratigraphic constraints for a Lutetian age of the Harrersdorf Unit (Rhenodanubian Zone): Implication for basement structure of the northern Vienna Basin (Austria)

The formations underlying the Neogene infill of the Vienna Basin are still poorly documented. Until now correlation of subsurface lithostratigraphic units with those of the Rhenodanubian nappe system and the Magura nappe system, outcropping at the basin margins, has been based on extrapolations. A recent drilling campaign in the Bernhardsthal oil field of the northern Vienna Basin in Austria reached the pre-Neogene basement and provided cuttings...
