Potential and Limitations of Strontium Isotopic Fingerprinting in Wood

Popis výsledku v původním jazyce

While the isotopic composition of strontium (87Sr/86Sr) is frequently used in archeological and environmental provenience studies, it remains unclear how bioavailable Sr in organic matter and the food chain reflects bedrock sources. Here, we present Sr isotopic measurements of 24 soil and 120 wood samples from four central European forests with variable basement geology. While 87Sr/86Sr values in bedrock (0.7035-0.7441) and soil (0.7043-0.7552) have a considerable span, wood 87Sr/86Sr values across sites have a much smaller range (0.7041-0.7245), which is closer to the large-scale atmospheric Sr signature in precipitation (0.7118). Comparable 87Sr/86Sr ratios for different tree species, cambial ages and root systems suggest that bioavailable Sr in wood is little affected by biotic factors. Given the strength of the atmospheric Sr signal we identify, archeological, environmental and forensic fingerprinting should consider high-resolution spatial isoscape modeling, for which this study provides a baseline for central Europe.
