Constraining the snowball earth: timing and duration of neoproterozoic glaciations using precise Re-Os geochronology. This project aims to investigate the onset and duration of major global glacial events during the period of Earth history when metazoan life first appeared. Understanding such processes will enable insights into both the rate and nature of evolutionary processes, and place constraints of ancient and modern climate models. This will be achieved by establishing a facility to obtain precise Re-Os isotope age data from sediments at Adelaide University (only the second such in the world), and studying sedimentary rocks preserved in the Centralian Superbasin. A basis for global stratigraphic correlation will also result from the intended program of work.
