“…The Santonian-Campanian contourites described presently are yet another example of Upper Cretaceous contourites formed along the edges of local bathymetric highs that, in turn, formed due to regional Late Cretaceous inversion tectonics. These highs and related contourites may be associated with uplifted basement blocks during thick-skinned inversion (Surlyk and Lykke-Andersen 2007;Krzywiec et al 2009Krzywiec et al , 2018Hübscher et al 2019), blocks mobilized above Zechstein evaporites during thin-skinned inversion (Stachowska and Krzywiec 2023), and compresionally-reactivated salt diapirs (Krzywiec 2006b(Krzywiec , 2012Krzywiec et al 2022a, and this paper).…”

“…Numerous examples of Upper Cretaceous-Palaeogene contour currents flowing along inversion-related uplifts have been reported from several European epicontinental sedimentary basins, such as the Norwegian-Danish Basin, the North German Basin, and the Polish Basin (e.g., Esmerode et al 2007;Surlyk and Lykke-Andersen 2007;Krzywiec et al 2009Krzywiec et al , 2018Krzywiec et al , 2022aGennaro et al 2013;Larsen et al 2014;Hübscher et al 2019;Stachowska and Krzywiec 2023). These currents were responsible for variations in lateral thickness, local incisions, the development of local unconformities, and stratigraphic pinch-outs, and profoundly influenced associated depositional architectures.…”

“…These structures are discussed in the context of diapir evolution and the regional axial depositional system that developed along both sides of the Mid-Polish Anticlinorium, the main regional inversion structure in Poland (cf. Mazur et al 2005;Krzywiec et al 2018;Stachowska and Krzywiec 2023).…”

This paper presents the results of seismostratigraphic interpretation of the Upper Cretaceous sedimentary succession preserved within two synclines flanking the Szamotuły diapir in northwestern Poland. This succession is characterized by a complex Santonian–Campanian internal geometry characteristic of contourites – that is, deposits formed by contour (bottom) currents. The aim of the present paper is to document these contourites using 2D seismic reflection profiles calibrated by the Obrzycko 1 well. The contourite drifts in the immediate vicinity of the Szamotuły structure exhibit elongated mounded shapes, with adjacent concave moats. At greater distances from the diapir, gradual aggradational patterns are observed. The formation of these Santonian– Campanian contourites was associated with growth of the Szamotuły diapir during regional compression and Polish Basin inversion. These contour currents and associated contourites formed an integral part of a regional axial depositional system developed within the flanks of the Mid-Polish Anticlinorium. Furthermore, this paper discusses the potential role of contourites as palaeomorphological indicators of palaeoslopes in varied geodynamics settings, such as inverting sedimentary basins, as opposed to the passive margins upon which they have been most commonly documented.

“…Recent years have brought several accounts on the effects of Late Cretaceous‐early Paleogene basin inversion in the southern Baltic Sea (Ahlrichs et al., 2022; Al Hseinat & Hübscher, 2017; Krzywiec et al., 2022; Pan et al., 2022; Sopher et al., 2016; Stachowska and Krzywiec, 2023). However, this study is the first to document the inversion structures at the scale of entire crust—from the Moho to base of the Cenozoic.…”

“…Furthermore, the area was affected by widespread extensional tectonics in the Late Devonian—early Carboniferous followed by late Carboniferous inversion (Krzywiec et al., 2022; Smit et al., 2018), and then next phase of extension and subsidence in Permian‐Mesozoic (e.g., Krzywiec, 2006a; Y. Maystrenko et al., 2008). Finally, the Late Cretaceous‐early Paleogene basin inversion vastly modified the pre‐existing tectonic features (e.g., Al Hseinat & Hübscher, 2017; Kley, 2018; Krzywiec, 2006b; Krzywiec et al., 2003, 2022; Mazur et al., 2005; Stachowska and Krzywiec, 2023). These superimposed tectonic events produced a complex structural pattern (Table 1) that impedes understanding of the crustal structure at the transition from the thick crust of the EEC to the thinner crust of the Paleozoic Platform farther SW.…”

The southern Baltic Sea is a peculiar area, where the Sorgenfrei‐Tornquist Zone (STZ), stretching from Bornholm into the North Sea, connects to the Teisseyre‐Tornquist Zone (TTZ) that continues SE up to the Black Sea. In this study, we show the structure and evolution of this controversially debated area, both on crustal and basin scale, by using three seismic reflection profiles combined with 2‐D potential field data. The results demonstrate that the southern Baltic Sea is underlain by a thick crust of the East European Craton with a Moho depth in the range of 38–42 km. The overall crustal architecture is shaped by three phases of localized stretching in the early Paleozoic, Devonian‐Carboniferous, and Permian‐Mesozoic. The most spectacular feature of the southern Baltic Sea is a zone of thick‐skinned compressional deformation produced by Late Cretaceous‐early Paleogene inversion, including a system of thrusts and back thrusts penetrating the entire crust in an 80–90 km wide inversion zone. ENE‐vergent thrusts are traced from the top of the Cretaceous down to the Moho and they are accompanied by back thrusts of opposite vergence, also reaching the Moho. Inversion tectonics resulted in the uplift of a block of cratonic crust as a pop‐up structure, bounded by thrusts and back thrusts, and the displacement of the Moho within the STZ and TTZ. The similar mechanism of intra‐cratonic inversion was recognized for the Donbas Foldbelt in eastern Ukraine, and it may be characteristic of rigid cratons, where deformation is localized in a few preexisting zones of weakness.
