New Radiocarbon Dates for the Vedde Ash and the Saksunarvatn Ash from Western Norway
Abstract The Vedde Ash Bed (mid-Younger Dryas) and the Saksunarvatn Ash (early Holocene) are important regional stratigraphic event markers in the North Atlantic, the Norwegian Sea, and the adjacent land area. It is thus essential to date them as precisely as possible. The occurrence of the Saksunar...
