Nature and distribution of frozen saline sediment on the Russian Arctic coast

Auteur :
BROUCHKOV, A.

Description :
This paper examines frozen fine-grained soils, mainly of Pleistocene and Holocene age, that are distributed along the Arctic coast at the surface and which contain soluble salts. Salinization is determined by both the conditions at formation, and subsequent processes at cryogenic temperatures. An increase in salinization with depth is observed. This is most likely caused by moving of salts from the upper permafrost layers as the result of the migration of pore water. Salinization in general increases with an increase in ice content. An important feature of the saline soils of the Russian Arctic coast is their heterogeneity.
