Trace Element Geochemistry of Igneous and Metamorphic Rocks

My research interests include the application of x-ray fluorescence and instrumental neutron activation techniques to the analysis of geological materials, and the interpretation of these data in terms of the origin and evolution of igneous and metamorphic rock suites. On a broader level this research leads to a consideration of trace element models for the composition and growth of the continental crust, and for the evolution of the crust-mantle system.
