Dilatant shear band formation and diagenesis in calcareous, arkosic sandstones, Vienna Basin (Austria).

Abstract The present study examines deformation bands in calcareous arkosic sands. The investigated units can be considered equivalent to reservoir units in the Matzen field in the Vienna Basin (Austria), which is one of the most productive oil reservoirs in central Europe. The outcrop exposes carbonate-free and carbonatic sediments of Badenian age separated by a normal fault. Carbonatic sediments in the hanging wall of the normal fault develop single and multistrand dilation bands with minor shear displacements (
