Materialising the Social Relationships of Hunter-Gatherers: Archaeological and Geochemical Analyses of 4th Millennium BC 'Slate Ring Ornaments' from Finland.

During the 4th millennium BC, an intensive artefact circulation system existed among the hunter-gatherer peoples of north-eastern Europe. Along with other goods, ring-shaped ornaments that were mainly made of different kinds of slates or tuffites were commonly distributed. Although commonly referred to as 'slate rings', these ornaments consist mainly of fragments of rings. In this paper, we suggest that the 'slate rings' were never meant to be intact, complete rings, but were instead fragmented on purpose and used as tokens of social relationships relating to the gift-giving system. By refitting artefact fragments together, analysing their geochemical composition, micro details, and use-wear, we were able to prove that these items were not only intentionally fragmented but also likely worn as personal ornaments. Moreover, ED-XRF analysis of 56 of the artefacts showed a correlation between their geochemical characteristics and stylistic detailing, suggesting different production phases or batches. Comparative data analysis confirmed the provenance hypothesis that the majority of the analysed objects, or at least their raw materials, were exported over hundreds of kilometres from the Lake Onega region.
