Abstract

The Cenozoic tectonic evolution of the Polish Platform reflects repeated changes in loading conditions at the AlpineCarpathian and ArcticNorth Atlantic margins of the Eurpean continent. After the Late CretaceousPaleocene main phase of the Mid-Polish Basin inversion, a second phase of limited uplift of the Mid-Polish Swell occurred during the MiddleLate Eocene. End Eocene and Early Oligocene subsidence of narrow grabens on the Fore-Sudetic Monocline was coeval with normal faulting in the East Alpine foredeep basin and the develop ment of the Central European rift system. At the same time the Outer Carpathian flysch basins were rearranged, presumably in response to the build-up of compressional stresses at crustal levels, whilst subsidence and erosion patterns changed in the Carpathian Foreland from being dominated by the NWSE trending Mid-Polish Swell to being cotrolled by the development of the WE trending Meta-Carpathian Swell. At the end of the Oligocene the Fore-Sudetic graben system propagated into the area of the Trans-European Su ture Zone and the Sudetes and remained active during the Early and Middle Miocene. This was paralleled by in tensified subduction activity and thrusting of the Carpathians and the develop ment of their flexural foredeep basin. A short early Sarmatian episode of basement in volving transpression along the SW mar gin of the Mid-Polish Swell correlates with the termination of north-directed nappe transport in the Outer Carpathians. This was followed by east ward migration of the subsidence centre of the Carpathian Foredeep Basin and the gradual termination of tectonic activity in the grabens of the Polish Lowlands. After a period of post orogenic relaxation the present-day compressional stress regime built up during the Pliocene and Qua te nary. In tensified ridge push forces exertedon the ArcticNorth Atlantic passive margins contribute to this compressional stress field that is dominated by collision-related stresses reflec ing c
