Structure-geomorphological features of the largest lakes of Russian North-West

Abstract

Lakes Ladoga and Onega are the largest lakes in the Russian North-West. They are very important from point of view of ecological social-economic aspects of this region for the first time, and they are significant for paleogeography, because lakes is the most representative banks of paleogeografical information about climate changes, especially in quaternary period. But this lakes are weakly studied, the most comprehensive studies at this lakes was at the beginning of 21 century (Makariev et al., 2002; Andreev et al., 2016; Subetto et al., 2009). This work based on results of fieldworks was carried out at the 2014-2019 on the Lakes Ladoga and Onega. During this work, seimoacustic profiling and bottom coring was carried out. The data obtained during field works make it possible to characterize composition of Upper-Pleistocene lacustrine deposits and geomorphological features of these lakes. As the result of data interpretation, geomorphological and geological maps of these lakes was drawn up. It makes possible to correlate structure-geomorphological features of Lakes Ladoga and Onega.
