We present geochemical data of soils sampled from two Late Iron Age (a.d. 550–1050) buildings at Bartsgårda on the Åland Islands, Finland. The houses had different constructions and use-patterns, one being an intensively used dwelling house, rich in finds, whereas the other, scarce in finds, had a more specialized character, linked to ceremonial rather than domestic activities. Systematic and targeted feature sampling was carried out to analyze 190 samples using energy dispersive X-ray fluorescence spectrometry (ED-XRF) to 1) identify floor/activity levels in the houses based on vertical and horizontal geochemical anomalies; 2) compare the anthropogenic activity signals of the buildings; and, 3) test a rapid and cost-efficient ex situ analytical strategy for geochemical characterization of archaeological soils. Although the long-term use of the site as a livestock paddock introduced some complexities, based on the geochemical and micromorphological data, the houses had several activity levels and markedly different anthropogenic profiles. |
