Continental rift development in Precambrian and Phanerozoic Europe: EUROPROBE and the Dnieper-Donets Rift and Polish Trough basins

摘要: Abstract Upper crustal structure and lower mantle character of the European continental lithosphere differ significantly from west to east. The processes rifting Phanerozoic western Europe's hotter, thinner crust compared with more stable, thicker (45 vs 30 km) Proterozoic East Craton is being investigated by EUROPROBE case studies eastern sedimentary basins. Dnieper—Donets basin transects southwestern part platform in a NW—SE direction, lying between Ukrainian Shield Voronezh Massif. Rifting took place early Frasnian until perhaps late Visean was accompanied major volcanic activity. distribution both affected pre-existing basement fault systems. syn- post-rift succession may be as thick 20 km Donets Trough. Basin evolution present geometry have been much “inversion” during Permian association Uralian orogenesis. Tectonic events Bathonian—Oxfordian (∼ 168−154 Ma) Turonian—Santonian 91−84 age are also recorded stratigraphy. Polish Trough lies along boundary domains, coincident Trans-European Suture Zone. presence this rheological paramount structurally controlling position subsidence analysis indicates an initial (late) Rotliegendes—Early Triassic syn-rift phase development. Subsequently, episodes increased tectonic rate occurred Oxfordian—Tithonian (≈ 157−146 beginning Cenomanian 95−90 Ma). episode likely signature second extensional event (correlated intensification within Arctic—North Atlantic rift system) while later precursor mild compressional, intraplate orogenic movements.
