Radiocarbon dating of varve chronologies; Soppensee and Holzmaar lakes after ten years.

Irka Hajdas, Georges Bonani, Bernd Zolitschka

Abstract


During the last decade, several radiocarbon-dated varve chronologies have been produced. The main goal at first was the extension of the (super 14) C calibration curve beyond 10,000 BP. This paper aims to discuss varve chronologies of Soppensee and Holzmaar Lakes. Although both chronologies encountered problems, high-resolution (super 14) C dating and relative varve time have been obtained for events during the Late Glacial.
