Development of geochronology techniques: enhancing methodology, protocols and accuracy of non-destructive ESR and U-series direct dating methods.

To understand human evolution, archaeologists require precise chronologies so as to compare and contrast fossil collections. While indirect dating of the sedimentary matrices of human occupation sites are considered somehow more precise than direct dating techniques, their accuracy is frequently poor.

To minimise the impact of direct dating on valuable and oftentimes fragile archaeological samples, new methods and protocols for non-destructive U-Th and ESR analyses are being developed and investigated.
