Abstract

The paper deals with dynamics of present morphologic processes and cover deposits of nival and subnival stages in the area to the north of the Hornsund Fiord. Qualitative and quantitative parameters of the processes are described on the basis of direct measurements and radiocarbon datings. A particular attention was paid to the action of frost and gravitational processes in the specific morphoclimatic conditions of a nival landscape stage. The cover deposits are described from the point of view of their origin and physico-chemical properties. The age of the covers is defined on the ground of radiocarbon datings of fossil plants found at the nunataks for the first time in 1973. These datings enabled to distinguish the development phases of the morphogenetic processes during Late Holocene.
