Abstract
In this study, we carried out to correlate of high-resolution reflection seismic patterns of sediment covers Lakes Gusinoye and Shuchye located near the eastern coast of Lake Baikal. For this purpose, we used high-resolution seismic data and sediment cores up to 2.7 m. Seismic stratigraphy records contain three contrasting episodes when the lake levels dramatically decreased. In result, there are probably hiatuses in the paleorecords from these lakes due to erosion of sediment cover at the lowest lake levels at the Late Pleistocene and Holocene.The core sediment record was based on distribution of biogenic silica, quarts, feldspar and total organic carbon obtained by FTIR method. The maximal age of the cores was 23.2 cal. ka BP. Significant climate changes in Baikal region happened ca. 22, 17.5 and 1.5 ka BP.
