Abstract
Studies of deposition processes in Bay Proval on the eastern side of Lake Baikal allow us to approach reconstruction of natural and man-caused events through the past 150 years on the basis of reliable sedimentological tracers. The tracers include fossil soil (1862), chlorinated organic compounds (since the 1950s), 137Cs (since 1953), and modern soil (1959). The project for investigation of recent sedimentation in the region around the Selenga delta offers an opportunity to decipher the unique natural microchronicle of natural and man-caused events in the Late Holocene.
