14C AGE, STABLE ISOTOPE COMPOSITION AND POLLEN ANALYSIS OF MASSIVE ICE, BOVANENKOVO GAS FIELD, CENTRAL YAMAL PENINSULA
The origin of the massive ice is important for understanding the Quaternary history of the Yamal region and to predict the occurrence of massive ice, which is important for gas exploration and the development of infrastructure. Massive ice bodies occur in the Bovanenkovo gas field area within sedime...

The origin of the massive ice is important for understanding the Quaternary history of the Yamal region and to predict the occurrence of massive ice, which is important for gas exploration and the development of infrastructure. Massive ice bodies occur in the Bovanenkovo gas field area within sediments such as layers, laccoliths, rods and lenses. Maximal thickness of the tabular ice is 28,5 m; mean thickness is about 8 m. Deposits of the third terrace underlying and overlapping the tabular ice had been formed from 25 ka BP to 20 ka BP, according to 14C dates. Oxygen-isotope values (δ18О) of massive ices are ranged from 12, 49‰ up to -22, 95‰. Deuterium (δD) values vary from -91, 7‰ up to -177, 1‰. Deuterium excess (dexc) changes from 3, 4 to 10, 6‰. Both homogenous and contrast distribution δ18О and (δD) vs. depths in massive ice bodies evidences the segregated and/or infiltrated-segregated manner of ice formation.
