The Polish and Ukrainian Carpathian Foredeep, about 600 km (376 mi) long and as much as 100 km (62 mi) wide, is part of the large sedimentary basin that stretches for more than 1300 km (816 mi) from the Danube in Vienna (Austria) to the Iron Gate on the Danube (Romania). To the west, the Carpathian Foredeep is linked with the Alpine Molasse Basin, and to the east, it passes into the Balkan foreland basin. Like other foreland basins, the Carpathian Foredeep is asymmetric and filled with predominantly clastic sediments of the Miocene age as much as 3 and 6 km (1.8 and 3.6 mi) thick at the Carpathian front in Poland and Ukraine, respectively. The molasse deposits of the Carpathian Foredeep are underlain by the basement of the European Platform, covered mainly by Permian-Mesozoic terrestrial and shelf sediments and locally by the Paleogene deposits. According to seismic, magneto-telluric, and well data, the platform basement with Miocene molasse cover dips southward underneath the Outer Carpathian nappes to a distance of at least 50 km (31 mi). The early to middle Miocene Carpathian Foredeep developed as a peripheral foreland basin related to the moving Carpathian front. The Paleozoic-Mesozoic and Tertiary strata of the Carpathian Foredeep are oil and gas productive.
