Abstract
The results of GPR data analyses have shown that the accretion form is a polygenic, steeply inclined glacio-fluvial delta foreset formed during the Pandivere stage of deglaciation as a result of consistent discharges of huge amounts of sediment materials from the melting ice-sheet and arriving from the south, west, north-west and south-west. During the maximal level of the Littorina transgression, the eastern part of the accretion form remained drained and represented a peninsula or island that was surrounded by the Littorina Sea from the west and north-east, but its western part was intensely eroded. At an absolute level of 8.5 m, there was a relatively long-term stabilization in sea level, and beach and submarine sand ridges formed that were subsequently unaffected by marine transgressions and were preserved as relict forms in the relief.
