“…On the other hand, very old rocks, especially those rich in potassium, have high 87 Sr/ 86 Sr ratios. For example, the estimates of average 87 Sr/ 86 Sr ratios for Archaean units of the Karelia domain are 0.7209–0.7476, and for Proterozoic units of the Svecofennian domain of Finland are 0.7169–0.7637 (Kaislaniemi, ).…”

Strontium isotope compositions of ancient sulphate deposits not only provide chemostratigraphic information but also offer insight into the system in which the evaporites precipitated. Primary gypsum from two Middle Miocene (Badenian) sections in southern Poland shows steadily higher 87Sr/86Sr ratios than those expected from a marine‐derived formation. The ratios are interpreted as the result of increasing inflow into the basin at the time of gypsum precipitation. Palaeogeographic reconstructions suggest that riverine runoff sources were situated in the West and East European platforms (to the north and east, respectively) and the Carpathians (to the south), which are mostly composed of Mesozoic sedimentary rocks; their dissolution cannot be responsible for the higher 87Sr/86Sr ratios recorded. We conclude that Archaean and Palaeoproterozoic igneous and supracrustal rocks of the Ukrainian Shield were the source of the higher 87Sr/86Sr ratios recorded in the Badenian primary gypsum. A distinctive decreasing trend of 87Sr/86Sr ratios from western Ukraine to southern Poland is explained by a consistent direction of brine inflow during gypsum crystallization (typical cyclonic circulation controlled by the Coriolis effect).

“…The 87 Sr/ 86 Sr ratios of the bedrock around the Iin Hamina region have been modelled as highly variable, with compositions ranging from 0.7098 to 0.8325 ( Fig. 1; (Kaislaniemi 2011)). A recent modelling study of the bioavailable 87 Sr/ 86 Sr ratios in soils for Northern Europe suggests probable values closer to the lower end (~0.715) as more likely (Hoogewerff et al 2019).…”

Source of strontium in archaeological mobility studies—marine diet contribution to the isotopic composition

The strontium isotope composition of human tissues is widely used in archaeological mobility studies. However, little attention is paid to the relative contributions of terrestrial versus marine sources of strontium in these studies. There is some debate over the role of a solid diet versus drinking water as the most important source of strontium for the human body, with related possibilities of misinterpretation of the archaeological record if only strontium isotope compositions of the biosphere are studied. However, there is a third component, marine strontium, which is commonly not assumed to contribute towards the strontium isotope composition of archaeological skeletal remains, especially in locations that are not directly coastal. To illustrate the potentially obfuscating effects of mixed Sr sources in a human population, we present a case study of twelve individuals from the medieval Finnish site Iin Hamina with a known dietary history. Our study shows that marine consumption is a significant factor explaining the strontium isotope composition of the Iin Hamina human remains, with implication of erroneous conclusions about immigration without prior knowledge of diet composition. Thus, future studies should always incorporate a rigorous analysis of dietary history, with special regard to potential consumption of aquatic resources, when strontium isotope analysis is used as a method in the study of palaeomobility.

“…In general, old granites typically have 87 Sr/ 86 Sr ratios between 0.710 and 0.740 (Bentley 2006). This is also likely to be the case in Finland (Kaislaniemi 2011). Even though currently there are only a small number of analyses available from Finland, the estimation derived from the Finnish bedrock varies between 0.710 and 0.840, with most values above 0.720 (Kaislaniemi 2011).…”

The High-Status Late Medieval Skull Shaped Relic in Turku Cathedral Finland – Study of the Origin with Oxygen and Strontium Isotope Analyses

The relics and associated reliquaries of Turku Cathedral are among the most significant early Christian artefacts in Finland preserved in situ. Despite their importance, they have not been the focus of scientific enquiry for a number of decades. This study has focused on one skull shaped relic, although the origin and name of its associated saint remains unknown. The relic is the only such example with high-status decoration in the Turku Cathedral collection and is covered with a red silk decorated with yellow yarn. The bones and fabric have been dated from the beginning of the modern era to the 13th century AD, and variance among the radiocarbon (<sup>14</sup>C) dates acquired from the bones shows the remains incorporate several individuals. In this study, oxygen and strontium isotope compositions were determined from fragmented bones and textiles. The results are the first isotope analysis performed on this collection housed in Turku Cathedral. Analysis indicates an origin from outside Finland, possibly elsewhere in northern Europe or an Alpine region. This helps take us a little closer to understanding the mystery associated with this sacred artefact.
