Description:
In recent years enormous success has been achieved in varve counting of the Eifel maar lakes, but a detailed correlation with the biostratigraphy has been missing. In this paper, we present new palynological results of the Lateglacial sequences from Holzmaar Lake and Meerfelder Maar Lake based on annually laminated sediments. In particular, the Meerfelder Maar has great potential, because, in contrast to the Holzmaar, the sequence between the Ulmener Maar Tephra (11 000 varve years BP) and the Laacher See Tephra (12 880 varve years BP) including the Younger Dryas is undisturbed and complete. Therefore, we currently use the Meerfelder Maar chronology (Brauer et al., 1999b) as an independent varve calendar for the biostratigraphy of the Lateglacial. The palynological signals of both maar lakes are in good agreement and can easily be correlated with one another and with type sections/type regions in northwestern Germany and Jutland. The sequences of the Eifel maar lakes have the quality of hypostratotypes with regional biozones based on an absolute time scale.
