ISOTOPIC GEOCHEMISTRY OF LAKE SIRITKUL SEDIMENTS (SOUTH URAL)

Maslennikova A.V., Udachin V.N., Deryagin V.V.

Information About Author:

Oxygen and carbon isotope content of Lake Siritkul sediments, accumulated during 11000–5000 14С yr. B.P. was studied. There was revealed coincidence of pollen-zones and climatic stages determined on the basis of isotopic analyses. The assumption of connection between atmospheric precipitation, evaporation and isotopic content of carbon and oxygen was confirmed with the help of pollen analysis.

Keywords: Holocene, lake sediments, stable isotopes of carbon, oxygen isotopes ratio, pollen analysis
