Mapping of spatial variations in Sr isotope signatures (Sr/Sr) in Poland - Implications of anthropogenic Sr contamination for archaeological provenance and migration research.

This study presents first isoscape maps of strontium isotope signatures and their spatial variation in Poland, based on ~900 samples of rocks, sediments, surface water, and flora. This dataset is supplemented by Sr/Sr ratios predicted for several carbonate rock units. High, radiogenic Sr isotope ratios (>0.
