Concentration and distribution of trace elements across the sequence of the Late Pleistocene sediments from the lake Medvedevskoye suggest the addition of materials other than those from a common source for the lake sediments of the region. The sediments of the lake Medvedevskoye carry some geochemical fingerprints which could be related the ET event that occurred at ca. 12.9 ka. Because such fingerprints are extremely subtle, the NW Russia can be considered to be the most remote eastern region of the extent of the Late Pleistocene airborne ET material. The sediments of the lake Medvedevskoye can also contain volcanic material from the eruption of the Laacher See (Germany) volcano and probably from other Late Pleistocene volcanoes of Western Europe and/or Iceland.

The article offers information on the study based on chronology of isolation of the Solovetskii archipelago lakes and rates of lake sedimentation. It also includes the results of lithological, micropaleontological, and radiometric investigations of the lake bottom sediments. It adds that the investigation was conducted at several lakes including Bolshoe Korzino, Svyatoe, and Bolshoe Zelenoe. It focuses on the use of radiocarbon dating regarding the investigation that was conducted at the Finnish Museum of Natural History, University of Helsinki, Finland.
