“…Localized subsidence during the Late Devonian led to formation of a 2.5 km thick sedimentary succession filling the NW-SE-oriented Lublin Trough (Narkiewicz, 2007). This extensional event was terminated by significant uplift during the "Bretonnian" tectonic phase at the transition from the Devonian to Carboniferous that caused widespread exhumation in the range of 1000-2000 m (Poprawa, 2006;Krzywiec et al, 2017a). The lack of Devonian strata over the remaining part of the SW slope of the EEP in Poland is usually attributed to post-Variscan exhumation in the latest Carboniferous and early Permian (Żelichowski, 1987;Narkiewicz, 2007).…”

“…Thick successions of such sediments have been drilled in Pomerania (NW Poland) west of the TTZ (Żelichowski, 1987;Narkiewicz, 2007). However, based on sedimentary facies models, it is postulated that the Devonian and lower Carboniferous succession could have initially extended further north and east than now, covering large areas of the SW slope of the EEP (Żelichowski, 1987;Matyja, 2006). This corollary is also supported by early Carboniferous illite K-Ar ages from the lower Paleozoic sediments of the Baltic and Podlasie basins (Kowalska et al, 2019).…”

Thermal history of the East European Platform margin in Poland based on apatite and zircon low-temperature thermochronology

Abstract. The Phanerozoic tectonothermal evolution of the SW slope of the East European Platform (EEP) in Poland is reconstructed by means of thermal maturity, low-temperature thermochronometry, and thermal modelling. We provide a set of new thermochronometric data and integrate stratigraphic and thermal maturity information to constrain the burial and thermal history of sediments. Apatite fission track (AFT) analysis and zircon (U-Th)/He (ZHe) thermochronology have been carried out on samples of sandstones, bentonites, diabase, and crystalline basement rocks collected from 17 boreholes located in central and NE Poland. They penetrated sedimentary cover of the EEP subdivided from the north to south into the Baltic, Podlasie, and Lublin basins. The average ZHe ages from Proterozoic basement rocks as well as Ordovician to Silurian bentonites and Cambrian to lower Carboniferous sandstones range from 848 ± 81 to 255 ± 22 Ma with a single early Permian age of 288 Ma, corresponding to cooling after a thermal event. The remaining ZHe ages represent partial reset or source ages. The AFT ages of samples are dispersed in the range of 235.8 ± 17.3 Ma (Middle Triassic) to 42.1 ± 11.1 Ma (Paleogene) providing a record of Mesozoic and Cenozoic cooling. The highest frequency of the AFT ages is in the Jurassic and Early Cretaceous prior to Alpine basin inversion. Thermal maturity results are consistent with the SW-ward increase of the Paleozoic and Mesozoic sediments thickness. An important break in a thermal maturity profile exists across the base Permian–Mesozoic unconformity. Thermal modelling showed that significant heating of Ediacaran to Carboniferous sedimentary successions occurred before the Permian with maximum paleotemperatures in the earliest and latest Carboniferous for Baltic–Podlasie and Lublin basins, respectively. The results obtained suggest an important role of early Carboniferous uplift and exhumation at the SW margin of the EEP. The SW slope of the latter was afterward overridden in the Lublin Basin by the Variscan orogenic wedge. Its tectonic loading interrupted Carboniferous uplift and caused resumption of sedimentation in the late Viséan. Consequently, a thermal history of the Lublin Basin is different from that in the Podlasie and Baltic basins but similar to other sections of the Variscan foreland, characterized by maximum burial at the end of Carboniferous. The Mesozoic thermal history was characterized by gradual cooling from peak temperatures at the transition from Triassic to Jurassic due to decreasing heat flow. Burial caused maximum paleotemperatures in the SW part of the study area, where the EEP was covered by an extensive sedimentary pile. However, further NE, due to low temperatures caused by shallow burial, the impact of fluids can be detected by vitrinite reflectance, illite/smectite, and thermochronological data. Our new results emphasize the importance of using multiple low-temperature thermochronometers and thermal modelling in connection with thermal maturity analysis to elucidate the near-surface evolution of platform margins.

“…The late Turonian to early Campanian (c. 80-90 Ma) onset of the tectonic inversion of the ISB, suggested by thermochronological data (Botor et al 2019, Sobczyk et al 2020, was coeval with cooling due to tectonic inversion in the Holy Cross Mountains and adjacent areas of the Mid-Polish Trough documented by thermochronological data (Botor et al 2018: fig. 3b, c;Łuszczak et al 2020). The seismic investigation results along the Mid-Polish Trough also suggest similar timing for the onset of tectonic inversion (Krzywiec et al 2018).…”

“…The highest frequency of the AFT ages is in the Jurassic and Early Cretaceous (Tab. 3) i.e., they are older than inversion of the German-Polish Basin (e.g., Senglaub et al, 2005;Resak et al, 2010;Łuszczak et al, 2020).…”

“…3; Krzywiec, 2002Krzywiec, , 2009. In contrast to the Mid-Polish Trough, where significant Late Cretaceous basin inversion took place (Botor et al, 2018;Łuszczak et al, 2020), the part of the Polish Basin extending over the TTZ and adjacent area of the EEP experienced only mild to little inversion (Krzywiec, 2009;Krzywiec et al, 2017a, 20017b). This is probably related to the rather shallow depth to the rigid Precambrian basement and the lack of Zechstein evaporites.…”
