A 14C-DATING AND OXYGEN-ISOTOPE DIAGRAM OF A HOLOCENE-REFORMED ICE WEDGE ON THE CHARA RIVER (TRANSBAIKAL REGION)

Abstract

The purpose of our work is to refine the age of the Holocene polygonal ice wedge complex in Terrace 1 of the Chara River, plot an isotope diagram, which allows one to reconstruct winter temperatures of the period of ice-wedge formation, and prove the possibility of active formation of ice wedges in the Holocene Optimum in even the southern regions of Siberia.
