Abstract
On both the distal and proximal sides of the Palivere end-moraine zone on the West Estonian Archipelago, a sporadic distribution of up to 25 m thick subaqueous waterlain glacial diamicton (WGD) was observed. The WGD lies at an altitude between - 15 and + 10 m relative to contemporary sea level. During the Palivere stadial the distribution area of the WGD was at least 50-60 m below the water table of the Baltic Ice Lake. The WGD was deposited at the grounding zone of the glacier by continuous subaqueous basal meltout from floating ice with minor involvement of sediment flows, dumping, and grounding. In texture, the WGD resembles glaciolacustrine clay with increased amounts of gravel and clay fractions. Compared to the basal tills of the area, the WGD contains less gravel (21.5% and 6.8%, respectively) but is rich in silt and clay fractions. Petrographic, mineralogical, and chemical analyses show a similar source for the Palivere basal till and the WGD.
