英文摘要 | The Spanish region of Almeria is well known for its rich geological records and its richness in archaeological remains. Sr isotopes have been applied in archaeology as a powerful tracing tool for individual human and animal mobility, but their application requires extensive regional baselines as reference against which the target materials can be compared. This study presents Sr concentrations and Sr-87/Sr-86 values of modern environmental proxies (plants, soils and surface waters) from southern Almeria to establish such a bioavailable Sr isotope baseline for this region. Additionally, this study evaluates differences in bioavailable Sr-87/Sr-86 signatures of the plants, soil leachates and surface waters and tests three soil leaching agents, ultrapure water (mq), 1M NH4NO3 and 0.1M HNO3, to better understand variations of Sr isotope signatures captured by the different proxies and to evaluate their suitability for baseline constructions. Our results define a wide range of Sr-87/Sr-86 values ranging from 0.70836 to 0.71630. Our data reveals a strong influence of the local surface lithology on bioavailable Sr-87/Sr-86 compositions. While the plants and soil leachates generally returned similar Sr-87/Sr-86 values, surface waters from the same sites sometimes returned significantly less radiogenic values likely due to transported, carbonate-derived Sr from their catchment areas. The different soil leaching procedures returned leachable fractions with similar Sr-87/Sr-86 values, but a slight bias was observed for soils with a carbonate component signifying the overall strong control of bioavailable Sr by carbonates. We propose to define bioavailable Sr isotope baselines as the average bioavailable Sr-87/Sr-86 ratio +/- double standard deviation ((X) over bar +/- 2 sigma) of 1) plants and soil leachates and 2) surface waters for each surface lithology. The soil and plant-based baselines define the narrowest range in Sr-87/Sr-86 for areas dominated by Cenozoic volcanic rocks while the widest range is seen in areas dominated by high grade Paleozoic metamorphic rocks. Due to the scarcity of surface water run-off in the arid region of southern Almeria, surface water based Sr-87/Sr-86 baselines could only be defined for sites dominated by Cenozoic sediments and high grade Paleozoic metamorphic rocks. |
