Besides being distinctive, a volcanic-ash layer has four other advantages for purposes of correlation: The aim of this paper is not to be comprehensive, but to provide a brief and timely general review of tephra studies and their methodologies, and to make a case for better linking tephra research to archaeology, all from a primarily Scandinavian perspective. Google Scholar Plunkett G: Council of Europe, Another form of dating is tephrochronology, so called because it employs the tephra ash layers generated by volcanic eruptions. Google Scholar Myrhe B: Linking the North Atlantic to central Europe: We cannot know whether the pollen core investigated during tephrochronology dating range contained any tephra at all, but if bog centre and margin can be linked to human occupation areas through step-wise sampling, tephrochronology can be made more directly relevant also to archaeological investigations — the latter are in as much pressing need for age control and cross-regional correlation as the environmental sciences.
