“…It is likely that the remaining samples exchanged varying proportions (15-100%) of their biogenic dentine Sr with soil derived material. Unlike enamel, dentine would appear to be unreliable as a reservoir of biogenic Sr. We suggest that acid pre-treatments of the sort discussed by Sealy et al (1991) and Grupe et al (1999) would not have been successful in removing diagenetic material for the majority of the dentine samples we have investigated. We believe the same considerations are likely to apply to archaeological and fossil bone.…”

“…Rib , femur (Grupe et al, 1997;Price et al, 1998) and other bones (Latkoczy et al 1998), which are continually remodelled in vivo, have been used in this way. These tissues, however, are known to be subject to diagenesis during burial and to require pre-treatment prior to analysis (Sealy et al, 1991;Price et al, 1992;Sillen and Sealy, 1995). Treatments involve washing or leaching in weak acids to remove diagenetic apatite which is considered more soluble than its physiologically constrained biogenic counterpart (Latkoczy et al 1998).…”

“…Procedures of this sort have been found to remove variable proportions of the Sr in fossil and archaeological bone samples prior to Sr-isotope analysis. Sealy et al (1991) and Sillen and LeGeros (1991) found that their solubility profiling technique typically removed ~25-30% of the Sr from samples which were considered to preserve biogenic material. Koch et al (1992) used a variant of the same procedure to wash samples of fossil salmon bone and noted a decline in Sr/Ca ratios between early washes and final sample solutions of ~5-40%.…”

“…Only six samples, all from chalk burials, were essentially unaffected (T  4), but only one of these (G318) appeared not to have been subject to substantial accumulation of diagenetic Sr. Diagenetic Sr accounted for ~34-79% of total dentine Sr for the other five. These estimates may be compared with the ~25-30% reduction in Sr typically reported for acid sample pre-treatments (Sealy et al 1991). A further nine samples, from both chalk and clay soils, appear to have exchanged ~15-76% of their biogenic Sr with that derived from the soil.…”

AbstractThe investigation of prehistoric human migration from the measurement of Sr-isotope ratios within preserved tissue is critically dependent on the preservation of biogenic Sr. A number of recent studies have involved isotope ratio measurements on samples of archaeological tooth and bone, but doubt remains as to the extent of diagenesis in various skeletal tissues and the effectiveness of procedures designed to decontaminate them. We have compared Sr abundance and isotope ratios in enamel and dentine from archaeological teeth in order to assess the integrity of the biogenic Sr signal preserved within the respective tissues. We conclude that enamel appears, in most cases, to be a reliable reservoir of biogenic Sr, but that dentine, and by implication bone, is not. The diagenesis of dentine is highly variable even between burials within a single site. For the majority of teeth, dentine diagenesis was not simply by addition of soil-derived Sr, but involved substantial, sometimes complete, turnover of the original biogenic material. We suggest that, for most of the samples investigated, current decontamination techniques may not have been effective in isolating biogenic Sr from dentine. Similar considerations are likely to apply to archaeological and fossil bone, but the possibility arises to use dentine and enamel measurements to assess the effectiveness of decontamination procedures which may then be used for bone.
