Project Details
Description
Until now, post-mortem uptake of uranium by mollusc shells has precluded accurate U-series dating of fossil shells using established methodologies. Using an innovative laser ablation-mass spectrometry technique combined with a predictive diffusion-adsorption model for U-uptake in shells, we will develop a new open-system U-series approach to dating fossil shells. This will provide the earth and archaelogical sciences with a reliable and accurate method for dating a wide range of shell-bearing deposits up to 400,000 years old, and new opportunities to investigate impacts of and links between climate and sea-level change, active tectonic processes, and the timing of human occupation and migration.
