Isotope Signature Of The Massive Ice Bodies On The Northeast Coast Of Chukotka Peninsula
The massive ice (MI) bodies are widespread phenomena on Chukotka coastal plains. Although they have been studying since 1930s, stable isotope method was applied for the ice beds quite recently. In this study cryostratigraphy and stable oxygen and hydrogen isotope composition of MI bodies on the extr...

The massive ice (MI) bodies are widespread phenomena on Chukotka coastal plains. Although they have been studying since 1930s, stable isotope method was applied for the ice beds quite recently.

It was concluded that studied MI bodies have intrasedimental origin and most likely are dated back to the Late Pleistocene age.
