Project Progress

In the last year, we have reported work on the origin of the crust from analysis of rare isotopes in Hadean zircons from Western Australia, established the ages of the oldest and best preserved sediments in Canada at Inukjuak (Quebec) and completed our analysis of multiple sulfur isotopes from the transition from an oxygen-poor to oxygen-rich surface across the Paleoproterozoic. The publications arising from this work are listed elsewhere in this report.In the last year, we have reported work on the origin of the crust from analysis of rare isotopes in Hadean zircons from Western Australia, established the ages of the oldest and best preserved sediments in Canada at Inukjuak (Quebec) and completed our analysis of multiple sulfur isotopes from the transition from an oxygen-poor to oxygen-rich surface across the Paleoproterozoic.
