Evidence from seismites for glacio-isostatically induced crustal faulting in front of an advancing land-ice mass (Rügen Island, SW Baltic Sea)

The Quaternary sequence of Mecklenburg-Western Pomerania: areas of specific interest and ongoing investigations

“…We still only have limited knowledge about the depositional environments and processes, the oscillation of the SIS during the LGM and early Late Glacial, and especially the deglaciation sequence of NE Germany between 25 and 14 ka, which has only been locally dated. The first unequivocal evidence of a Weichselian ice advance reaching MWP has been dated at about 25-20 ka (Kenzler et al, 2015(Kenzler et al, , 2017(Kenzler et al, , 2018Pisarska-Jamroży et al, 2018). This time roughly coincides with the palaeo-geographical reconstructions of the SIS extent in the southwestern Baltic Sea area by Hughes et al (2016).…”

Micromorphology and clast microfabrics of subglacial traction tills at the sea cliff Dwasieden: evidence of polyphase syn- and post-depositional deformation

“…The fine-grained I1 sediments are regarded as having accumulated in a glacilacustrine environment close to the ice margin (Ludwig, 1954/55;Ludwig and Panzig, 2010;Brumme, 2015). The interbedded gravel layer and the outsized clasts represent ice-rafted debris formed by dumpstones and dropstones from drifting ice bergs (Pisarska-Jamroży et al, 2018b).…”

Sea cliff at Glowe: stratigraphy and absolute age chronology of the Jasmund Pleistocene sedimentary record

“…Several recent studies have clearly shown that luminescence dating can solve issues of the timing of the individual ice advances approaching NE Germany (e.g. Lüthgens et al, 2011;Kenzler et al, 2015Kenzler et al, , 2017Pisarska-Jamroży et al, 2018). These new luminescence age data raise the question of whether the traditional stratigraphy and interpretation of the main Weichselian ice advances of NE Germany have to be modified (Hardt, 2017;Kenzler, 2017).…”

“…Lüthgens et al, 2011;Hardt, 2017). Furthermore, interstadial deposits of Weichselian age intercalated between till units have yielded reliable luminescence ages (Kenzler et al, 2015(Kenzler et al, , 2017(Kenzler et al, , 2018Pisarska-Jamroży et al, 2018). Luminescence dating is based on the principle that the energy of the ionising radiation flux from the surrounding sediments (U / Th series nuclides, K and Rb -alpha, beta, and gamma radiation) and of cosmic radiation is stored within the crystal lattice of quartz and feldspar minerals, due to impurities and lattice defects (Aitken, 1985).…”
