“…The geological structure determined the development of the structural-denudation relief. During the Quaternary period, the study area was repeatedly exposed to ice cover (Biske, 1959;Ekman and Iljin, 1995;Evzerov, 2010;Korsakova et al, 2023;Lukashov, 2003). However, glacial and fluvioglacial landforms were formed as a result of the activity of the Rugozero (Salpausselkä I) stage deglaciation (Figure 1a).…”

Archeological sites of ancient people have been identified on the Karelian coast of the White Sea, near the mouth of the Keret River. The aim of our studies was to determine the position of the sea shoreline, correlate archeological sites with it, date ancient settlements, and reconstruct the paleoclimatic conditions and habitats of ancient people. We analyzed the bottom sediments of five small lakes that became separated from the sea at various times during the Holocene, using a combination of Quaternary geological methods such as spore-pollen, diatoms, radiocarbon (14C), etc. New data have been obtained regarding the timing when the study area resurfaced and the possibility of its subsequent habitation by humans. We have generated q curve illustrating the relative displacement of the White Sea coastline, thus reconstructing the migration of the sea coastline. The article also presents parameters detailing the differentiated movements of various blocks of the crystalline basement along the Karelian coast of the White Sea. Additionally, we produced paleogeographic reconstructions describing the natural conditions of the habitat of ancient people and the development of the territory from the beginning of the Holocene to the present day. Our findings indicate that people likely began inhabiting this area no earlier than 6500 years ago. Furthermore, we propose that a potential catastrophic event, such as a tsunami)= resulting from an earthquake near Veliky Island and the Velikaya Salma Strait (Kandalaksha Bay), occurred no earlier than 2600–3000 years ago.

“…(a) The eastern flank of the Fennoscandian Ice Sheet during deglaciation and the location of studied areas (rectangles). Ice marginal positions at different stages (thick lines) are according to Korsakova et al (2023a, 2023b) (Abbreviations show the stades: Lg–Luga (15.7–14.6 cal kyr BP), Nv–Neva (14.1–13.9 cal kyr BP), SSI –Salpausselkä I (c. 12.7–12.0 cal kyr BP) and Tr-Ly–Tromsø-Lyngen in the northeast of the region (c. 12.5–12.0 cal kyr BP, after Vorren and Plassen (2002)), SSII – Salpausselkä II (c. 12.0–11.6 cal kyr BP). (b) Location of the cored lake basins 1–9 in the Teriberka area, the elevation of lake threshold is indicated in brackets; a crosses indicate the coring sites in the largest lakes; topography is shown by a 20 m contour interval; the location of coastal landforms at an elevation of 20–22 m is shown by dotted lines.…”

“…The Polyarny area (Corner et al, 2001) is located close to the Younger Dryas Salpausselka I (cf. Korsakova et al, 2023b) end moraine zone, on the western side of the Kola fjord, 120 km east of the Kirkenes–Nikel area. The Dalnie Zelentsy area is located between the Luga (Keiva I) and Neva (Keiva II) marginal moraine zones (Korsakova et al, 2023a).…”

The paper presents isolation basin stratigraphy in bottom sediments from nine lakes in the Teriberka area on the Kola Peninsula, northwestern Russia. Isolation contacts in these basins, identified from lithological and diatom analysis, were used together with 25 radiocarbon dates, to construct a relative sea-level (RSL) curve for the Holocene. Records of marine water re-influx were found in the sediment sequence from one lake, located at c. 17 m a.s.l. The re-influx of marine water seems to be caused by the mid-Holocene (Tapes) transgression and tsunami event. The RSL curve indicates several phases in the postglacial evolution of the Kola coast. An early phase of rapid sea-level fall of c. 32 m around 11,500 cal yr BP, at a rate of c. 40 mm per year, corresponds to glacio-isostatically induced emergence following deglaciation at the Younger Dryas and beginning of the Holocene. In the time interval between c. 11,000 and 7600 cal yr BP, either a stillstand or a slight rise in relative sea level, cresting at about 21 m a.s.l., is suggested in the Teriberka area. This is followed, after c. 7300 cal yr BP to the present day, by a slow glacioisostatic emergence with an average rate of about 2–3 mm per year.
