Description :
The paleoclimatic record from bottom sediments of Lake Baikal (eastern Siberia) reveals new evidence for an abrupt and intense glaciation during the initial part of the last interglacial period (isotope substage 5d). This glaciation lasted about 12,000 yr from 117,000 to 105,000 yr B.P. Lithological and biogeochemical evidence of glaciation from Lake Baikal agrees with evidence for the ice sheet in northwestern Siberia during this time period and also with cryogenic features within the strata of kazantzevo soils in Southern Siberia.
