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.
