Sažetak
Miocene evolution of the Carpathian-Pannonian region was influenced by four important geotectonic events. The Oligocene-Early Miocene collision of the Alpine – Carpathian chain with the North European platform led to an extrusion of the Alcapa microplate from the East Alpine domain. This process has been associated with compressional tectonics in front of the moving plate and was accompanied by subduction of the thinned crust below the Western Carpathian orogene front and accretionary prism development. In the contact zone between the two twisting microplates an overthrusting of the Szolnok flysch sediments onto the Tisza-Dacia microplate took place during the Eggenburgian and Ottnangian. Miocene extrusion of the Alcapa superunit continued by the activation of sinistral displacement zone on the East Alpine – Western Carpathian boundary during the Karpatian (opening of the Vienna basin). Subduction pull in front of the Carpathians led to extension of the overriding superunits and was followed by initial rifting period in the back-arc domain. The Middle Miocene active elongation of the Alcapa and Tisza-Dacia microplates, due to subduction retreat in the northern and eastern front of the Carpathian orogene, led to wide synrift subsidence of individual basins in the back-arc basin system. The Badenian and Sarmatian basin development (Vienna, Danube, Great Hungarian Plain, etc.) was controlled by updoming of mantle masses which generated NW-SE extension in the western and central part of the region. The basins in the eastern part of the back-arc area (Transcarpathian and Transylvanian) were indirectly influenced by subduction process and show a NE-SW to E-W extension in this time. The basin evolution was accompanied with voluminous acid and calc-alkaline volcanism. During the Sarmatian the development of northern part of the Outer Carpathian accretionary prism has been finished. The Upper Miocene back-arc extension was induced by the Eastern Carpathian subduction pull and/or thermal postrift subsidence in the Pannonian domain. Rapid sedimentation occurred in the Danube and Great Hungarian Plain Basins. During the Pannonian and Pontian only the formation of the southern part of the Eastern Outer Carpathian accretionary prism continued.
