(super 14) C and (super 18) O in Siberian syngenetic ice-wedge complexes.

Abstract


We discuss the possibility of dating ice wedges by the radiocarbon method. We show as an example the Seyaha, Kular and Zelyony Mys ice wedge complexes, and investigated various organic materials from permafrost sediments. We show that the reliability of dating (super 18) O variations from ice wedges can be evaluated by comparison of different organic materials from host sediments in the ice wedge cross sections.
