Abstract

The results of the study of lake sediments in the North-East of Russia are presented. The reasons for the abnormally high values of magnetic susceptibility in the transition layers from the Late Pleistocene to the Holocene are considered. The magnetic fraction of Lake Grand sediments is represented by detrital titanomagnetites and magnetites. In the sediments of the Gryazevoye, Sosednee, Vodorazdelnoye, and Sapog lakes, high values of magnetic susceptibility are due to autigenic iron sulfides, mainly greigite. The data obtained do not confirm the well-known assumption about the presence of an impact event at the boundary of the Pleistocene and Holocene.
