Stratigraphy of Vistulian glaciogenic deposits and corresponding thermoluminescence dates in the lower Vistula region, northern Poland

Abstract

Drozdowski, Eugeniusz & Fedorowicz, Stanislaw 1987 06 01: Stratigraphy of Vistulian glaciogenic deposits and corresponding thermoluminescence dates in the lower Vistula region, northern Poland. Boreas, Vol. 16, pp. 139–153. Oslo. ISSN 0300–9483. Recent stratigraphical and sedimentological studies of Vistulian deposits in the lower Vistula region combined with the results of thermoluminescence dating substantiate the tripartite scheme of chronostratigraphic subdivision of the Vistulian glaciogenic sequence presented earlier by Drozdowski. All the thermoluminescence dates provided by till and intertill waterlain sediments refer to two major stadials which, in the light of sedimentological analyses, seem to represent two independent glacial cycles: an older, dated approximately to the period 59,000–51,000 years B.P., and a younger, dated to the period 17,000–15,000 years B.P. The dividing interval, named the Grudziadz Interstadial, was rather cool in nature. The evidence for this interstadial, apart from the significant break in glaciogenic sediment deposition, comprises some infills of subglacial stream trenches cut during the earlier deglaciation, loess‐like silts, fossil sand wedges, and transgressive marine deposits, the latter occurring in restricted areas in the northern part of the region.

The fan-like forms in the southern margin of the Mazovian Lowland area (Central Poland): a new high-resolution textural-timing study

“…Therefore, the multiple phases of patchy deflation and aeolian sand accumulation are reflected here. Primary, Unit 1 can be correlated with the GS-9 to GS-12 events (Blockley et al 2012) corresponding partially with the Grudziądz Interstadial, despite being cool in its nature (Drozdowski and Fedorowicz 1987). Mechanical weathering, slope processes, alternating mineral-organic deposition and the aeolian episodes are believed to occur in the Grudziądz Interstadial (Manikowska 1999).…”

Constraints on the Late Saalian to early Middle Weichselian ice sheet of Eurasia from field data and rebound modelling

“…The top of these marine deposits occurs up to 5 Á20 m a.s.l. (Drozdowski 1995;Drozdowski & Federowicz 1987) and we adopt this as a lower limit to sea level during the early part of the Eemian. Further east, at Prangli (near the mouth of the Gulf of Finland) as well as in Riga Bay and coastal Latvia, marine sediments cover the entire Eemian, beginning and ending with cold-water brackish facies of Late Saalian and Early Weichselian ages, respectively, and with 'normal marine' conditions in the early Eemian, but no useful limiting estimates of sea level appear to be available.…”

Fluvial responses to the Weichselian ice sheet advances and retreats: implications for understanding river paleohydrology and pattern changes in Central Poland

“…Its cause, despite the lack of meltwater feeding, may have been an increase in the efficiency of surface runoff affected by the expansion of continuous permafrost (Renssen and Vandenberghe 2003;Buschers et al 2005Buschers et al , 2007. These climate conditions in the area of the Toruń Basin is proven by wedge casts filled with well-sorted sands at 27 ka ago (Drozdowski and Fedorowicz 1987;Drozdowski and Szupryczyński 1987).…”
