Fields of Study
(1) Integrated use of trace elements and Pb, Nd, Sr, Hf, and Os isotopes to model the petrogenesis of ultramafic xenoliths, arc lavas, layered mafic intrusions, and continental flood basalts; (2) Application of U/Pb and 40Ar/39Ar geochronology to providing constraints on the evolution of continetal and oceanic arcs; (3) Kinematic evolution of orogenic belts; and (4) Mantle and lower crust chemical geodynamics.
