Detailed mass spectrometric U-series analyses of two teeth from the archaeological site of Pech de lAze II: implications for Uranium Migration and Dating
We report Th/U ages obtained by thermal ionization mass spectrometry of cross-sections of two teeth from the archaeological site of Pech de l'Aze II. The aim of this study is to reconstruct the pathways and time dependency of uranium uptake into different constituents of the two teeth. A previous ESR dating study of the two teeth yielded age estimates in the range of about 130,000 to 200,000 years, which was in agreement with the geological assignment of Riss for layers from which the specimens...[Show more]
