The geographic distribution of bioavailable strontium isotopes in Greece – A base for provenance studies in archaeology

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