Research Interests

Research: Isotope Geochemistry

T40 Sector 54 VG Thermal Ionization Mass Spectrometer (TIMS)

Analyses of isotopic ratios in the Rb-Sr, Sm-Nd and U-Pb systems provide evidence to establish the timing of events and unravel the complexities of fluid-rock interactions in deeply buried metamorphic rocks as well as the surficial environments which control river chemistry. Previous studies have determined the age and crustal evolution of early Archaean terrains in Scotland, Western Australia and Zimbabwe, modeled fluid-flow in metamorphic rocks exposed in the Pyrenees, Maine, Vermont and Nevada.  I have also worked on the structure and magnitude of fossil ocean ridge hydrothermal systems in Cyprus and Oman and investigated the kinetics of Pb release from the highly resistant mineral zircon.

CRIUS Project

Carbon Research into Underground Storage (CRIUS) investigates the interactions between CO2 and the minerals and fluids within geological reservoirs to predict the stability of such storage sites.   Quantifying the reactions and determining changes in permeability and mineralogy at depth using chemical and Sr isotopic fluxes will enhance knowledge on the long term storage of CO2 and the economic viability of this process as a potential solution to climate change.

Riverine Chemistry

The chemical and isotopic fluxes carried by major rivers draining the Himalayan-Tibetan orogen. This is to test the hypothesis that such major orogens impact on global climate. Much of this work concentrates on distinguishing between inputs from carbonate and silicate minerals because silicate weathering impacts on climate.
