Brief description Nanoscale repositories of the geological record of Earth and other planets. Rhenium-Osmium (Re-Os) dating is used widely to infer Earth's evolution, but most samples are hydrated, with consequent mobility of Re, which is problematic for interpretation of isotope results. This project will solve this problem by determining the effects of hydration on Re and Os. Further, our knowledge of the mobility of Re and related elements will allow us to recognise rocks that once interacted with water, even after that water has gone, providing a tool to read the record of Earth's earliest oceans. Our new methods will enable Re-Os dating with clarity and confidence, with profound implications for understanding of Earth and extra-terrestrial planetary evolution.
