Stable isotope composition (δ¹⁸О, δ²H and dexc) of massive ice bodies, Eastern Chukotka
Massive ice (MI) bodies exposed in floodplain and terraces at 7 sites have been studied from 1985 to 2020. In recent research stable oxygen and hydrogen isotope composition of massive ice bodies on the extreme North-Eastern Chukotka (near Lavrentiya settlement and Koolen' lake) have been studie...

description |
Massive ice (MI) bodies exposed in floodplain and terraces at 7 sites have been studied from 1985 to 2020. In recent research stable oxygen and hydrogen isotope composition of massive ice bodies on the extreme North-Eastern Chukotka (near Lavrentiya settlement and Koolen' lake) have been studied in detail. It was concluded that studied massive ice bodies have intrasedimental origin and most likely are dated back to the Late Pleistocene age. Mean δ18O values range from –18.5 ‰ to –15 ‰ whereas mean δ2H values range from –146‰ to –128 ‰ that is higher than expected for the Late Pleistocene ice bodies in this region, which most likely resulted from isotopic fractionation during freezing of water-saturated sediments in a closed system when forming ice isotopically enriched compared with initial water. The analysis of co-isotope ratios for massive ice shows that initial water is mainly of meteoric origin (precipitation, water of lakes and taliks). |
