   The Vienna basin represents an area of major subsidence along the north-west edge of the Alpine-Carpathian internal basin system. The Neogene fill of the basin was deposited on an allochthonous stack of nappes during and after their thrusting over the autochthonous basement (Bohemian Massif) which is covered by Jurassic, Upper Cretaceous, and Tertiary Molasse sediments. The Mesoozic cover on the Bohemian massif shows evidence of Middle Jurassic rifting, followed by a shelf-and-basin sedimentation in late Jurassic times, and then by late Cretaceous transgression. After periods of erosion from Eocene to Early Miocene, Molasse was deposited in the foredeep in front of the Alpine-Carpathian orogen, represented by the Waschberg, Flysch, Calcareous Alps, and central Alpine-Tatride zones. The slowing and termination of Miocene thrusting in the western (Alpine) region, and continued movement in the northern (Carpathian) part of the orogenic belt, led to tension, causing the Vienna basin.
   The directions of the strike of Alpine-Carpathian frontal units north of Vienna reflects the trend of pre-existent sub-Alpine basement structures. Total organic carbon measurements in all stratigraphic units of the basin, and correlations of oils and source-rocks, suggest that the most important source-rock (based on volume, contents of organic matter, and thermal history) is the autochthonous Upper Jurassic (Malmian) marl. It reached the oil window during the last phase of overthrusting in Miocene times. The high subsidence rate of the basin floor during Middle Miocene times accelerated the oil generation in the underlying source rock and initiated migration. During late Miocene to Pliocene times the source-rock reached the gas generation stage, and migration occurred along the major fault system into the reservoir. The importance of the Vienna basin as a major oil and gas providence is due to the fact that a source-rock of up to 1000 m
