Figures & Tables

Fig 1

Microregions of the Niemodlin Plain and location of investigated sites, Siedliska and Przechód, with digital elevation model (DEM).

Fig 2

Sedimentary succession, radiocarbon and OSL ages of deposits at Siedliska (A) and Przechód (B) sites.

Fig 3

Depositional succession at Siedliska (A-D) and Przechód (E-H) sites: A – general view at the Siedliska site; B – S-2 unit with large-scale involutions and ice-wedge cast (arrow); C – fluvio-aeolian deposits (S-3 unit) with the fossil soil (arrow) in top of unit; D – aeolian deposits within coversand (S-4 unit) and stoss slope of dune (S-5 unit); E – top of P-1 unit, and aeolian deposits within coversand and bottom part of moving dune lee slope; F – soil within the lee slope of dune (top of P-3 unit); G – aeolian deposits within arm of dune (P-4 unit); H – climbing ripple lithofacies (arrow), deposited up the lee slope.

Fig 4

Relative probability density functions (Berger 2010) for all samples are presented on the scale of age.
