The finding of buried soil in the Last Glaciation region represents, in many respects, an exclusive event. Until now, only one locality of Holocene soil in the buried position had been known in the eastern Baltic region. It is situated at the apex of the Gulf of Finland, several kilometers southeast of Station Ligovo near the previous Settlement of Koierovo, where soil with high humus content was found in a 3- to 5-m-deep hole in the suture of the second terrace at an altitude of 20-22 m. The soil was stripped by several pits at a depth of 0.8-1.4 m. Near the Settlement of Koierovo, between the moraine of the Last Glaciation and the buried soil, one can see sands (often with pebbles and boulders) overlain by clay 0.25-0.55 m thick. Westward, about 4 km off the Settlement of Gorelovo, the soil in pits is replaced at a similar depth by peat interlayers (0.1-0.25 m thick) in analogous stratigraphic conditions. However, the peat commonly overlies the basal moriane or its rewashed variety. Data obtained for the soil buried in t he wedge-shaped structure suggest that the studied wedge and the whole local system of such structures in the neighborhood are related to seismogenic rather than cryogenic processes. Hence, we should revise the interpretation of the specific class of wedge-shaped structures that are widespread in the Leningrad district.
