Roberta Rudnick

Professor (Geochemistry and Petrology, Continent Formation and Evolution)
My research focuses on the origin and evolution of the continents, including the continental lithospheric mantle. Emphasis is placed on integration of data from a wide diversity of sources, including petrography, petrology, major and trace element geochemistry, isotope geochemistry, and geophysics in order to determine the bulk crust composition of the crust, the processes that have influenced its composition through time and why the Earth has continents. I have also been investigating the lithium isotope system as a tool for tracing fluid flow, continental weathering and crustal recycling.
