My research interests focus on the chromium geochemical cycle and the information Cr-isotopes can disclose on the cause and mechanism of rapid perturbations in palaeo-environments leading to mass extinctions. This may become a powerful redox indicator when coupled with other geochemical proxies.
Chromium isotopes may also be used to detect the signature of large meteorite impacts in the geological record such as the Stac Fada suevite in North-West Scotland. The 2008 paper “A Precambrian proximal ejecta blanket from Scotland” can be found here:
