Under the silt deposits of the tidal flat a gravel-clay series was found to occur. Connecting this series with the glacial till covering the lowest marine terrace and with the erosion pavement in the lowest part of the outwaśh plain gave rise to the hypothesis that there might be a record of glacier oscillation. By dating a sample taken from the gravel series substrate, the age of the oscillation was estimated at less than 6370+/- 120 years BP.}, type={Article}, title={The development and relief of the Petuniabukta tidal flat, central Spitsbergen}, URL={http://www.czasopisma.pan.pl/Content/111233/PDF-MASTER/1989_3_379-384.pdf}, keywords={Arctic, Spitsbergen, Petuniabukta, tidal flat, fossil glacial and fluvio-glacial deposits}, }
