Variations in δ¹⁸O, δ²H, and the Concentration of Pollen and Spores in an Autochthonic Heterogeneous Massive Ice on the Erkutayaha River in the Southern Part of the Yamal Peninsula

The objective of our work is to study the new massive ice deposit in the valley of the Erkutayaha River in the southern part of the Yamal Peninsula, determine the concentration of stable oxygen and hydrogen isotopes in the ice and study the pollen and spore in the ice, to determine the conditions of ice formation based on these data, and show that massive ice in these region are of the heterogeneous autochthonic type and segregation (infiltration-segregation) and injection genesis similar to those deposits that were recently studied in the regions near Yamal, on the Bovanenkov deposit close to the Harasavey and Marre-Sale settlements.
