The application of87Sr/86Sr in prehistoric mobility studies requires accurate strontium reference maps. These are often based from present-day surface waters. However, the use of agricultural lime in low to noncalcareous soils can substantially change the87Sr/86Sr compositions of surface waters. Water unaffected by agriculture in western Denmark has an average87Sr/86Sr ratio of 0.7124 as compared to an average of 0.7097 in water from nearby farmland. The87Sr/86Sr ratio obtained from samples over 1.5 km along a stream, which originates in a forest and flows through lime-treated farmland, decreased from 0.7131 to 0.7099. Thus,87Sr/86Sr-based mobility and provenance studies in regions with low to noncalcareous soils should be reassessed. For example, reinterpreting the iconic Bronze Age women at Egtved and Skrydstrup using values unaffected by agricultural lime indicates that it is most plausible that these individuals originated close to their burial sites and not far abroad as previously suggested.

The Early Nordic Bronze Age oak coffin burials include some of Europe’s best preserved human remains. Although traditional typological examinations thereof have not always found clear foreign references, recent provenance investigations from Egtved and Skrydstrup suggest that the two women were of non-local provenance. In order to investigate potential mobility patterns and how these might or might not be related to the archaeological evidence, we conducted comprehensive multi-analytical investigations on the Ølby Woman, another key female oak coffin burial. Her grave included large metal items, the remains of a corded skirt and a glass bead recently identified as of Egyptian origin. Strontium isotope analyses of the dental enamel of Ølby’s first, second and third molars investigate her provenance and potential mobility through childhood. Furthermore, we conducted lead isotope analyses and craft technical analyses of her belt plate and sword/dagger. Our results reveal that the Ølby female’s strontium isotope signatures fall within the local baseline, suggesting that she was of local origin. The metal provenance studies and craft technical studies of the belt plate and sword suggest that the objects were manufactured in Scandinavia, while the raw materials for each item were imported from different places in Europe.

Strontium Isotope Ratios

Strontium isotope ratios (87Sr/86Sr) of archaeological samples (teeth and bones) can be used to track mobility and migration across geologically distinct landscapes. However, traditional interpolation algorithms and classification approaches used to generate Sr isoscapes are often limited in predicting multiscale 87Sr/86Sr patterning. Here we investigate the suitability of plant samples and soil leachates from the IRHUM database (www. irhumdatabase.com) to create a bioavailable 87Sr/86Sr map using a novel geostatistical framework. First, we generated an 87Sr/86Sr map by classifying 87Sr/86Sr values into five geologically representative isotope groups using cluster analysis. The isotope groups were then used as a covariate in kriging to integrate prior geological knowledge of Sr cycling with the information contained in the bioavailable dataset and enhance 87Sr/86Sr predictions. Our approach couples the strengths of classification and geostatistical methods to generate more accurate 87Sr/86Sr predictions (Root Mean Squared Error=0.0029) with an estimate of spatial uncertainty based on lithology and sample density. This bioavailable Sr isoscape is applicable for provenance studies in France, and the method is transferable to other areas with high sampling density. While our method is a step forward in generating accurate 87Sr/86Sr isoscapes, the remaining uncertainty also demonstrates that finemodelling of 87Sr/86Sr variability is challenging and requires more than geological maps for accurately predicting 87Sr/86Sr variations across the landscape. Future efforts should focus on increasing sampling density and developing predictive models to further quantify and predict the processes that lead to 87Sr/86Sr variability.
