In summary, the northern part of the Suurpelto
area has a thinner sequence of fi ne-grained deposits.
There are mainly massive clays with a varved
structure and coarser (silt, sand) mineral layers that
represent earlier periods in BSB history, namely
the Baltic Ice Lake and Yoldia Sea phases. In the
southern part of the Suurpelto area these Baltic Ice
Lake and Yoldia Sea deposits have been covered
The authors are grateful to the Suurpelto project
partners, particularly to the city of Espoo for providing
geotechnical information on the study area
