Kartierung lokaler bioverfügbarer Isotopien (Sr, Pb, O) und Applikation des Isotopenfingerabdruckes auf archäologische Fragestellungen

这个分项目的目的是应用第一阶段建立的跨高山的Inn-Schlack-Etsch通道考古地层同位素图，包括稳定同位素比87 Sr/86 Sr、δ 18 O、208 Pb/204 Pb、207 Pb/204 Pb和206 Pb/204 Pb。现在将其应用于子项目4+5、6和7的选定考古问题。研究基质几乎完全由人类和动物的火化生物考古发现组成，尚未在稳定同位素分析方面进行系统的开发。在第一阶段的过程中，通过使用“期望最大化”算法对迄今为止建立的数据集进行分析，得出的结果是，在排除热不稳定的δ 18 O的情况下，将原始的5维同位素指纹减少到4维，从而允许对起源地进行充分的定义，这进一步与高概率相结合。在该项目的第一阶段，考古-地质子项目（原TP 1）和矿物子项目（原TP 2）有不同的研究目标，但这两个子项目现在在第二阶段结合起来。通过使用各种矿物学方法，已经建立了考古骨/牙齿磷灰石完整性的矿物学标准目录，现在可用于同位素数据的系统验证。

This subproject aims at the application of the isotopic map for archaeological strata of the transalpine Inn-Eisack-Etsch passage, which has been established in the course of phase I, consisting of the stable isotopic ratios 87Sr/86Sr, delta18O, 208Pb/204Pb, 207Pb/204Pb und 206Pb/204Pb. It shall now be applied to selected archaeological problems of subprojects 4+5, 6, and 7. The research substrate nearly exclusively consists of cremated bioarchaeological finds of humans and animals, which have yet not been exploited systematically in terms of stable isotope analysis. The analysis of the data sets established until now by use of the "expectation maximization" algorithm in the course of phase I led to the result that the reduction of the original five dimensional isotopic fingerprint to four dimensions under exclusion of the thermally instable delta18O permits a sufficient definition of place of origin, which is furthermore coupled with high probabilities. While during phase I of this project, the archaeometric-geological subproject (former TP 1) and the mineralogical subproject (former TP 2) had separate research goals, both subprojects are now contextually combined in phase II. A catalogue of mineralogical criteria for the integrity of archaeological bone/tooth apatite has been established by use of a variety of mineralogical methods and is now available for a systematic validation of isotopic data.
