- Sr isotopes are a powerful tool used to reconstruct human mobility in archaeology. This requires extensive bioavailable 87Sr/86Sr baselines used as reference for deciphering potential areas of origin. We define the first extensive bioavailable Sr isotope baselines for the different geographical regions and surface lithologies of Greece by combining new Sr data with previously published bioavailable 87Sr/86Sr data. We present 82 new Sr concentrations and 87Sr/86Sr signatures of plants, soil leachates, surface waters and spring waters from Central Greece and combine these with published baseline values from all over Greece. We define individual baselines for ten of the thirteen geographical regions of Greece. We also provide soil leachate 87Sr/86Sr ratios from the two archaeological Bronze Age sites of Kirrha and Ayios Vasileios in Central and Southern Greece and demonstrate the validity and applicability of the new baselines for these sites. The bioavailable 87Sr/86Sr compositions of Central Greece define a narrow range of 87Sr/86Sr values between 0.70768 — 0.71021, with the widest range observed for the soil leachates. Sr derived from carbonate weathering appears to be the most important Sr source sampled by the proxies. There is an overall larger variability in baseline ranges of the different geographical regions, the narrowest is that for West Greece and the widest that for West Macedonia. In addition, we computed statistical Sr isotope ranges for the five main surface lithological groups characterising the sampling sites of the various proxies. Narrowly ranged, unradiogenic bioavailable Sr isotope signatures are typical of areas characterised by igneous outcrops as well as by Cenozoic and Mesozoic sediments. Areas, where Palaeozoic and Precambrian bedrock outcrops dominate, produce significantly wider ranges. Our study promotes the usefulness of multi-proxy baselines for geographical reference purposes and thus their promising applicability for future human mobility studies. © 2021 Elsevier B.V.

- In this paper we report the results of the stable carbon and nitrogen isotope analyses of humans from two Middle Bronze Age cemeteries at Asine, Greece: Barbouna (n=6) and the East Cemetery (n=13). In general, the dietary pattern of adults and juveniles shows a heavy reliance on mainly terrestrial foods; C3 plants and a varying amount of animal protein (meat, milk or dairy products). The high nitrogen values of some individuals from the East cemetery indicate a substantial consumption of animal protein, although the carbon values show that no detectable amounts of marine foods, or C4 plants such as millet had been consumed. High nitrogen values as well as the high slaughter age of domestic animals, as found in previous studies point towards a significant utilization of milk and dairy products at Asine. A low increase of nitrogen values in subadults younger than one years of age from Barbouna compared to females at the East cemetery indicates that these children may have been fed breast milk as well as supplementary foods. Therefore, despite the poor preservation and uneven sample size, the Asine isotopic data give us information on diet during the MH period, as well as variation between the members of the community.
