Abstract

A fracturation study allows the study of tectonic evolution of the Vienna Basin, considered as a "thin skined pull-apart'. The Ottnangian-Karpathian stress-field (18.5-16.5 Ma) was characterized by a NNW-SSE compression. During Badenian-Sarmatian times a NE-trending, left-lateral strike-slip zone was formed. At the end of the Sarmatian the stress-field is marked by a weak short ENE-WSW compression - NNW-SSE extension. Pannonian-recent stress field was similar to middle Miocene one with a more expressed dominance of extension. One can prove a rotation of the maximal horizontal stress axis from NNW-SSE to ENE-WSW during Ottnangian-Sarmatian times. The origin of these rotations is the continental escape of the North-Carpathian and East-Alpine domains. -from English summary
