Abstract
Climatic changes during the last stages of landscape evolution in Makhtesh Ramon are mainly revealed by pollen assemblage of dated alluvial terraces. Loess units, as well as calcic horizons found within the alluvial sections, are considerd as indicators of wetter climate and as markers for correlation. The lower fluvial landforms: recent stream, flood-plain, and terrace I were deposited in the Holocene under extremely arid climate. The alluvium of terraces II (uppermost Pleistocene) and IV (the end of the Middle Pleistocene) was formed during the periods of semiarid climate. During wetter periods, which correspond with the Riss, Early Wurm, and Late Wurm glacial epochs in Europe, three thick (4-8 m) loess horizons were deposited in Makhtesh Ramon. The alluvium of terrace III (the middle of the Late Pleistocene) was formed under arid climatic conditions. -from Author
