“…Climate and, seasonality, which influences catchment discharge, also control the 87 Sr/ 86 Sr ratios of rivers (e.g. Land et al, 2000;Palmer and Edmond, 1989). Assessing the 87 Sr/ 86 Sr and Sr content of waters together is helpful in identifying the main lithologies from which the strontium isotopic composition of the water has been derived (e.g.…”

Sr/ 86 Sr reference maps (isoscapes) are a key tool for investigating past human and animal migrations. However, there is little understanding of which biosphere samples are best proxies for local bioavailable Sr when dealing with movements of past populations. In this study, biological and geological samples (ground vegetation, tree leaves, rock leachates, water, soil extracts, as well as modern and archeological animal teeth and snail shells) were collected in the vicinity of two early medieval cemeteries ("Thuringians", 5-6th century AD) in central Germany, in order to characterize 87 Sr/ 86 Sr of the local biosphere. Animal tooth enamel is not appropriate in this specific context to provide a reliable 87 Sr/ 86 Sr baseline for investigating past human migration. Archeological faunal teeth data (pig, sheep/goat, and cattle) indicates a different feeding area compared to that of the human population and modern deer teeth 87 Sr/ 86 Sr such as freshwater bivalve shells and tree cores were examined in order to track potential historic anthropogenic contamination of the water and the vegetation. The data obtained from the archeological bivalve shells show that the modern rivers yield 87 Sr/ 86 Sr ratios which are similar to those of the past. However, the tree cores registered decreasing 87 Sr/ 86 Sr values over time towards present day likely mirroring anthropogenic activities such as forest liming, coal mining and/or soil acidification. The comparison of 87 Sr/ 86 Sr of the Thuringian skeletons excavated in the same area also shows that the vegetation samples are very likely anthropogenically influenced to some extent, affecting especially 87 Sr/ 86 Sr of the shallow rooted plants.

In gen eral, the non-ma rine wa ters are char ac ter ized by higher 87 Sr/ 86 Sr val ues as compared with val ues of the nor mal Mio cene sea wa ter (Palmer and Edmond, 1989). In a closed ba sin sys tem, the lo cal, al tered plagioclase and smectite could have been a pos si ble source of stron tium for the cal cite which crys tal lised at a later stage of diagenesis.…”
