| dc.description.abstractEn | U-series datings are method of choice for tens of years in various domains, especially in archaeology, thanks to a large applicability (from few thousand years to 600 ka), theoretically on a wide range of carbonate materials (from speleothems to biominerals). This radiometric dating method is therefore considered as an important tool for investigating the Middle and Upper Pleistocene, beyond the period of applicability of radiocarbon. Today, the geochronological potential of this method is still largely unexploited in this field due to the limitations of the common protocol, which involves sample dissolution with spike addition and ion exchange chromatography. This approach is not suitable for small, valuable samples with very low uranium content (ultra-traces, <10ppb) and showing particularly complex diagenesis (open systems). Yet, these characteristics are specific to many samples, which are very abundant on most archaeological sites (eggshells, teeth, snail shells, etc.), and not yet fully exploited. | |
