BURIED SOILS IN THE SANDS OF THE URAL STEPPE REGION AS THE INDICATORSOF PALEOENVIRONMENTAL CONDITIONS DURING THE HOLOCENE

The comparative study of paleosols buried under archeological monument s of the Bronze Age and Medieval epoch and under eolian sediments of t he Early and Middle Holocene has been performed over the territory of sandy terraces in the Ural steppe region. As a result, a chronosequenc e characterizing the soil state during different periods of the Holoce ne was obtained. Its analysis enabled us to reveal the main stages of soil development and deflation processes in the region within the last 10 000 to 12 000 years. The Holocene dynamics of landscape and climat ic conditions in the steppes of the southern Urals is characterized on the basis of paleosol data.
