“…The deformation model is shown in Figure 17. The orientation of the main fault and its location in the tectonic graben very likely indicate rather end deformation/disaggregation bands that developed above a larger, subsurface blind fault (see Brandes et al 2018Brandes et al , 2022aBrandes et al , 2022b. Minor deformation structures within facies Sr, Sh are similar to those described by Pisarska-Jamroży & Weckwerth (2013).…”

“…The fault activity might be related to the reactivation of the faults due to ice loading during glaciation. The fault most probably developed the expression of syn-or post-Saalian (Odranian) activity along one of a number of basement faults (Brandes & Tanner 2012, 2022a, 2022b.…”

“…Krzyszkowski 1993a, modified) The faults are probably of tectonic origin (Mazur et al 2010, Štěpančíková et al 2010, Różycka & Migoń 2017, Stemberk et al 2019 strengthened by the instability of the sediments on a steep slope. These faults may have been formed by grain rolling and a related reorganization of the grain fabric (see: Brandes et al 2018Brandes et al , 2022aBrandes et al , 2022b, thus they are disaggregation bands and might indicate neotectonic activity above a branch fault, e.g. of the Sudetic Margin Fault, and in the tectonic Roztoka-Mokrzeszów Graben (Fig.…”

The article presents the results of research from the Mokrzeszów site in the Sudetic Foreland. Lithopetrographic and sedimentological analyses of sediments from the Middle Polish Glaciations (Early Saalian, Odranian, MIS6) in this area indicate the overrepresentation (90–95%) of large Scandinavian erratics. The deposits, representing a repetitive sequence of Gp-Gms-Sp-Sh/Sr(Dmm) lithofacies, accumulated during at least two episodes of glacial outburst floods and six sedimentary cycles. High-energy flows are estimated for the Gms and Gp facies at about 5 m∙s−1 and low-energy flows indicate 0.8 m∙s−1 for the Sp/Sh/Sr facies, to the lack of flow (Fm). The sedimentary sequences confirm the existence of a fan, which may have originated as a subaqueous steep coarse-grained fan in glacial-flow-lake-outburst floods that formed between the ice sheet front and the morphotectonic edge of the Sudetic Marginal Fault line and within the Roztoka-Mokrzeszów Graben, or as an aerial, piedmont fan on the Sudetic Marginal Fault edge. The sediments show discontinuous deformations – gently sloping faults and fractures from glacioisostatic stresses. The fault activity is probably related to the reactivation of the faults due to ice loading during or after the older Saalian glaciation.

The reactivation of faults and possible impact on barrier integrity marks a critical aspect for investigations on subsurface usage capabilities. Glacial isostatic adjustments, originating from repeated Quaternary glaciations of northern Europe, cause tectonic stresses on pre-existing fault systems and structural elements of the North German and Norwegian-Danish basins. Notably, our current understanding of the dynamics and scales of glacially induced fault reactivation is rather limited. A high-resolution 2D seismic data set recently acquired offshore northeastern Langeland Island allows the investigation of a fault and graben system termed the Langeland Fault System. Seismostratigraphic interpretation of reflection seismic data in combination with diffraction imaging unravels the spatial character of the Langeland Fault System along an elevated basement block of the Ringkøbing-Fyn High. In combination with sediment echosounder data, the data set helps to visualize the continuation of deep-rooted faults up to the sea floor. Initial Mesozoic faulting occurred during the Triassic. Late Cretaceous inversion reactivated a basement fault flanking the southern border of the elevated basement block of the Ringkøbing-Fyn High while inversion is absent in the Langeland Fault System. Here, normal faulting occurred in the Maastrichtian-Danian. We show that a glacial or postglacial fault reactivation occurred within the Langeland Fault System, as evident by the propagation of the faults from the deeper subsurface up to the sea floor, dissecting glacial and postglacial successions. Our findings suggest that the Langeland Fault System was reactivated over a length scale of a minimum of 8.5 km. We discuss the causes for this Quaternary fault reactivations in the context of glacially induced faulting and the presentday stress field. The combination of imaging techniques with different penetration depths and vertical resolution used in this study is rarely realized in the hinterland. It can therefore be speculated that many more inherited, deep-rooted faults were reactivated in Pleistocene glaciated regions.
