The radar signatures and age of periglacial slope deposits, Central Highlands of Germany
Abstract Determining the age of periglacial slope deposits (head) in the Central Highlands (Mittelgebirge) of Germany is a research challenge because of the lack of dateable organics and the contentious role of the Laacher See Tephra (LST) as a dating indicator.
