   Structural data from the Calcareous Alps, from the Vienna- and Styrian basin and from the Bakony mountains support a Late Miocene E-W compressional event which affected the entire Alpine-Carpathian-Pannonian system after 9 Ma (Maeotian) and prior to 5.6 Ma (Pliocene). Compression terminated Early to Middle Miocene eastward lateral extrusion of the eastern Alps and reverted the shear sense on strike-slip faults which bounded earlier extruded wedges such as the Salzachtal-Ennstal fault and the Mur-Mürz-Vienna Basin fault system. E-W directed compression terminated upper plate extension in the Pannonian area and tectonic subsidence in the Vienna- and Styrian basin. In the Pannonian Basin, the change from extension to Late Miocene compression during the postrift phase could explain the pronouced postrift subsidence by stress-induced downward flexure of the loaded lithosphere.
   Late Miocene E-W compression occurred coeval with the youngest E-directed thrusts in the eastern Carpathians during final soft collisional convergence. Up to the Middle Miocene, slab pull during subduction of the European plate below the Eastern Carpathians caused subduction roll back and upper plate extension of the Pannonian area. Subduction retreat was replaced by soft collision after up to 60 km thick continental crust entered the subduction zone. During the period of collisional convergence E-W-directed compressive stress was transmitted across the subduction boundary into the upper plate. Compressive stress was transferred through the uppermost brittle crust of the earlier extended Pannonian region far into the Eastern Alps. E-W compression terminated during the Pliocene when the Pliocene to recent NNW-SSE compressive stress field was established in Central Europe
