Аннотация: The objective of our work is to study the new mas sive 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 (infiltrationsegregation) and injection genesis similar to those deposits that were recently studied in the regions near Yamal, on the Bovanenkovо gas field, close to the Harasavey and Marre Sale settlements. The joint analysis of the distribution of stable isotopes and pollenspore remains in the massive ice on the Erkutayaha River allows us to conclude that this is an intraground (autochtonous) heterogeneous massive ice. The horizontal surrounding sediments was formed first as a result of infiltration–segregation ice release during the freezing of a draining beach. As a result of the further freezing, a closed talik was formed under the deposit. Its further freezing led to the upward injection of water under pressure, formation of the stock deposit of injection ice, and deforma tion of the overlying ice deposit formed earlier.
