Аннотация
The results of rock magnetic study of the core Sagan-Nur-2021-I from the bottom sediments of the glacial lake Sagan-Nur, located in the central part of the Oka plateau (Eastern Sayan), are presented. Based on the study of magnetic susceptibility anisotropy and scalar magnetic parameters, the Lake Sagan-Nur hydrodynamics is reconstructed. It is shown that the abrupt change of the Lake’s hydrodynamic environments is associated with the inflow of various volumes of the regional glacier melt waters into its basin as a result of degradation of both surface and subsurface glaciation. Taking into account the age model based on seven AMS 14C-dates, the reconstruction of changes in the hydrodynamic regime and sedimentation conditions in Lake Sagan-Nur for the last 14 thousand years in the context of climatic fluctuations over the Late Pleistocene-Holocene time is proposed.
