Abstract

For the first time for the Baikal rift zone, radiocarbon dates of humus horizons of buried Holocene soils in the profiles of debris flow fans were obtained on the right bank of the Irkut River along the Munch-Sardyk Ridge. Three stages of debris flow activity in Holocene have been identified: high (early Holocene – 10 thousand cal years ago), medium (3 thousand cal years ago – present) and low (between 10 and 3 thousand cal years ago). Apparently, the debris flow activity was determined by climatic conditions in the region and has been associated with the change of atmospheric precipitation. At the beginning of the Holocene precipitation exceeded their current level and one-time accumulation of debris flow deposits reached up to 5 m in thickness.
