On unique stone beaches on the Arctic coast of the Kola Peninsula
The results of studies of 11 stone beaches on the coast of the Barents Sea in the area of the Teriberskaya Bay have been presented. The studies were carried out from 2017 to 2019. As a result of the work, the structure of the beaches, their size, the composition of clastic material and the relations...
