Human Mobility in the Final Eneolithic Population of Święte, Jarosław District, South-Eastern Poland: Evidence from Strontium Isotope Data

Strontium isotope ratios (87Sr/86Sr) were applied to investigate provenance amongst the Final Eneolithic population at Święte (sites 11, 15 and 20) in the Subcarpathian region, south-eastern Poland. The study used 11 human enamel samples collected from the niche graves of the Corded Ware culture. To obtain base-line information on the local Sr isotope composition seven animal enamel samples were also examined. They were found in the adjacent archaeological sites of the Mierzanowice culture at Mirocin and Dobkowice, which have the same environmental and geological background as the sites at Święte. The investigated individuals from Święte display a wide spectrum of Sr isotope signatures, from 0.7094 to 0.7109. Because a comparison of human 87Sr/86Sr values from Święte with Sr animal signatures from Early Bronze Age sites in the area is not unambiguous the local range of 87Sr/86Sr values were based on published data for the Subcarpathian population of the Corded Ware culture. Strontium isotope ratios indicate that only three males with the most radiogenic 87Sr/86Sr values exhibit local signatures. Values below 0.7103 document individuals born outside of the Subcarpathian region. Among these are all women and children, two males and one individual with undetermined sex. The probable homeland of the non-local individuals were areas along the northern and eastern margins of the Carpathian Foredeep in Poland and Ukraine.
