Abstract.

 
The object of this research is the most southern massive ice in the Yamal Peninsula, located on the left bank of the Erkutayakha River (68°11ʹ18ʺ N, 68°51ʹ39ʺ E). A dislocated ice massif occurred in the 15-18 m exposure of the sandy layer. Its total length is about 100 m. The ice massif is composed of different types of ice. There are four types of ice: 1) pure matte white ice with a large number of gas xenogenic inclusions; 2) crystal clear ice, sometimes with soil inclusions; 3) gray ice with a steel tint, layered parallel to the slope of the upper surface of the massive ice; 4) gray block-ice, lies in the form of tiles. Each type of the ice was examined, and 10 samples of ice from different parts of the outcrops and of ice of different types have been selected for pollen study. The results of this study allowed more adequately evaluating the origin of the ice.
