The stratigraphic framework for the Upper Pleistocene of the glaciated Russian Arctic: changing paradigms
The development of stratigraphic ideas and terminology for the area of Late Pleistocene glaciation beyond the limit of the Fennoscandian ice sheet is discussed. The original meaning and subsequent distortions of the Siberian stratigraphic terms Zyryanka, Karginsky, Sartan and others are described. S...
