Dating Duvensee (abgeschlossen)

Dr. John Meadows, Dr. Harald Lübke

Interpreting radiocarbon results from early Mesolithic sites in Duvensee

Radiocarbon results from the Mesolithic sites at Duvensee, south-eastern Schleswig-Holstein, date the occupation of these sites to an extended period between the ninth and seventh millennia cal BC. Each site may only have been used for a brief period, however – in some cases, perhaps only for a single short season.

The wonderful preservation of organic materials in these structures, coupled with precise excavation techniques, mean that these sites are ideally suited to the application of Bayesian chronological modelling methods for the interpretation of radiocarbon results.

Duven 11 - GIS-model and chronology

As the 3D GIS model of Duvensee site 11 is completed the complex stratigraphic sequence is being used to refine the dates of the existing radiocarbon samples and to provide realistic estimates of the dates of platform construction and abandonment – and even for the deposition of particular finds. The same methods will be used to assess the potential of radiocarbon dating to provide precise chronologies for the other sites and their lithic assemblages, and to relate the occupation of each site to the palaeoenvironmental sequence.

Fig. 3: Calibration of individual radiocarbon results from Duvensee sites 1, 2, 6, 8, 9, 12, 13, 19 and 21, compared to the estimated dates of the start and end of occupation at site 11, derived from a Bayesian model of all radiocarbon results from this stratified sequence (individual results not shown).

Radiocarbon measurements which were made since the 1970s on Duvensee bog sites show that at least 7 sites at Duvensee date to the calibration plateau between 9000 and 8300 cal BC. Inspection of calibrated dates gives an exaggerated impression of site longevity. Because radiocarbon dating has become more precise over time, new work is nescessary to extend the already existing Bayesian model of Duvensee 11  to all Duvensee bog sites to obtain a more realistic chronology, and to link the archaeological record to the high-resolution palaeo-environmental reconstructions of the region now available.

We started in 2014 with site Duvensee 13, selecting 13 new radiocarbon samples which will help to test not only the intra-site contemporaneity, but also the chronological relationship between site 13 and other Duvensee sites.
