Pleistocene eolian processes in southern West Siberia and their geomorphic consequences

Abstract

Several stages of the eolian morphogenesis are distinguished; the youngest one is dated back to the Pleistocene-Holocene boundary, older one- about 15,000 years ago, and the third - at the beginning of the Karginsk (mid-Late Pleistocene) interstadial. Still earlier phases of eolian processes can be traced in sequences of loess and similar deposits. Stages of eolian morphogenesis and loess sedimentation are supposed to correspond to certain regime of the atmospheric circulation.
