“…5) with the present lowest 87 Sr/ 86 Sr ratios exhibited the same 87 Sr/ 86 Sr ratio for their 7th leach and residue (Table 2) suggests that the plateau region of the Sr/Ca 'leach progress' curve was obtained. However, if the diffusion profile spans the entire thickness of the tooth enamel and post-mortem Sr has been pervasively incorporated into the bioapatite, no amount of sequential leaching will be able to isolate a purely biogenic component (Nelson et al, 1986;Sillen, 1986;Tuross et al, 1989).…”

In this paper, we investigate the potential use of oxygen and strontium isotope ratios (d 18 O p and 87 Sr/ 86 Sr) measured in archaeological fish enamel as provenance indicators. d 18 O p and 87 Sr/ 86 Sr were measured in a suite of archaeological carp remains recovered from the Anatolian townsite of Sagalassos dated to the Early Byzantine period (AD 450e650) and compared to that of modern fish, river and lake waters from the Anatolian region. We used sequential leaches in weak acetic acid to remove diagenetic Sr from fossil tooth enamel, monitoring the effectiveness of this approach by measuring the Sr/Ca ratios of the leachates via an isotope dilution thermal ionization mass spectrometry method (ID-TIMS). d 18 O p values mostly excluded a riverine origin. 87 Sr/ 86 Sr ratios of one fish overlapped with the 87 Sr/ 86 Sr signatures of two lakes in the Anatolian region, and at least one lake (Gölcük) could be removed as a candidate owing to a very distinctive 87 Sr/ 86 Sr signature not found in any of the fish remains. Most of the tooth samples analyzed could not be assigned a precise geographical origin since the 87 Sr/ 86 Sr ratios measured in enamel did not match that of any of the local lakes selected as potential origin. This result suggests that carp may have originated from lakes that have not yet been sampled, although this conclusion is not supported by other archaeological evidence. Alternatively, the lack of correspondence between lakes and fish Sr isotope ratios highlights several possible sources of uncertainties including spatial heterogeneity in 87 Sr/ 86 Sr ratio within a lake, the contribution of dietary strontium to the 87 Sr/ 86 Sr ratio of fish tooth enamel, and post-mortem alteration of the tooth Sr isotope signal during fossilization. In spite of the high precision of the strontium isotope analyses and the wide range of variation in the surface waters of the Anatolian lakes and rivers, this method may remain limited to distinguishing between lakes situated in regions of bedrock of very distinct age and geology until these sources of uncertainty are more fully investigated.

“…Because its chemical behaviour and atomic radius are similar to that of calcium, strontium commonly substitutes for calcium in the crystalline lattice of hydroxyapatite in teeth and bone (Likins et al 1960;Schroeder et al 1972;Nelson et al 1986). Therefore, the bone strontium content and isotopic composition will reflect the isotopic composition of the geological region in which a person lived before death.…”

The Use of Strontium Isotope Analysis to Investigate Tiwanaku Migration and Mortuary Ritual in Bolivia and Peru

Strontium isotope analysis is applied in South America for the first time in order to investigate residential mobility and mortuary ritual from ad 500 to 1000. While Tiwanaku‐style artefacts are spread throughout Bolivia, southern Peru and northern Chile during this time, the nature of Tiwanaku influence in the region is much debated. Human skeletal remains from the site of Tiwanaku and the proposed Tiwanaku colony of Chen Chen have been analysed to test the hypothesis that Tiwanaku colonies, populated with inhabitants from Tiwanaku, existed in Peru. Strontium isotope analysis supports this hypothesis by demonstrating that non‐local individuals are present at both sites.

“…The ratio of stable isotopes in the collagen molecule is a function of its amino acid composition (Ambrose 1993;Grupe and Turban-Just 1998;Nelson et al 1986). Accordingly, the integrity of collagen, especially its original amino acid composition (in the following referred to as "collagen quality"), is significantly important for the validity of the isotopic data.…”

Experimental chemical degradation compared to natural diagenetic alteration of collagen: implications for collagen quality indicators for stable isotope analysis

Stable isotopic ratios from archaeological bone collagen are valid palaeodietary indicators, but depend on sufficiently well preserved molecules and several collagen quality criteria have to be fulfilled (mostly collagen wt%, C%; N%, C/N molar ratio). For a reassessment of these quality criteria, and a better understanding of the chemical degradation of bone collagen, experimentally degraded modern bones and 54 archaeological human bones were investigated. In the course of the experimental degradation, alterations of isotopic ratios were paralleled by altered collagen quality criteria. The contrary was found in the case of the archaeological specimens. This implies that the commonly used collagen quality criteria may be insufficient and do not guarantee that stable isotopic values of the gelatine extracts will still represent the original biological signal.
