Funded Activity Summary

Low-grade metamorphic phosphate geochronology: High-precision dating of ancient crustal fluid flow, hydrothermal mineralisation and the "Great Oxidation Event". Reliable dating techniques are required to obtain precise ages for ancient crustal fluid flow. Current techniques suffer from inheritance and isotopic resetting, problems that are particularly pronounced in early Precambrian rocks. This project will employ new analytical techniques to date phosphate minerals recently identified as potentially important new chronometers of ancient fluid flow, providing the first precise tectonothermal history of the Archaean Pilbara Craton. The project will also establish the age of giant iron-ore deposits across the Hamersley Province, test the various models for iron-ore formation, and provide a minimum age for the oxidation of the Earth's surface.
