Abstract

A complex of mineralogical and geochemical data from the south of Western Siberia indicates that the middle Holocene warm and dry epoch ended 5.5–4 cal ka BP with the further onset of more humid and cold conditions in the region. Significant changes in the regional climate probably occurred about 3.6–3.1 cal ka BP that is marked by an increase in the content of carbonates in the sediments, and by changes in vegetation. A general trend in the content of Mg in the carbonate fraction of lake sediments clearly shows a variation in water salinity as a response to climate change. There was a cyclical change of periods of drying/humidification of the Holocene climate of southern Western Siberia.
