Stable strontium isotopic ratios from archaeological organic remains from the Thorsberg peat bog.

Stable strontium isotope ratios in archaeological finds have frequently been used to determine their place of origin, in order to reconstruct migration and trade. Peat bogs offer favourable burial conditions for the preservation of organic remains such as woollen textiles and leather by a natural tanning process. However, these finds are impregnated by peat substances including contaminant strontium which is likely to mask the original (87)Sr/(86)Sr isotopic ratio of the specimens.

Local or nonlocal? A research of strontium isotope ratios of teeth and bones on skeletal remains with artificial deformed skulls.

The analysis of strontium isotopic composition of teeth and bone served as an approach to determine nonlocal individuals with artificially deformed skulls in Teuton and Gepid sites. A differing Sr-isotopic composition between tooth and bone from the same skeleton reveals a residence change between early childhood and the last ten years before death. The results show that most Teuton and Gepid individuals investigated are local habitants.
