Kay's research concentrates on the applications of petrology, geochemistry, and mineralogy to problems of the origin and evolution of the continental crust, with particular emphasis on the relation of regional tectonics to magmatic processes, the formation of the lower crust, and the evolution of ore deposits. This work has implications for understanding natural disasters, including volcanic eruptions and earthquakes. The research involves field studies and chemical analysis of rocks and minerals; the laboratory work makes use of the instrumental-neutron-activation, ICP-MS, mass-spectrometry, and electron-microprobe facilities at Cornell.
