Theme 1: Granites in geodynamic sites, planets and time

Annie Bauer Junior Keynote Speaker /University of Madison-Wisconsin
Bernard Bonin Overview Speaker /Université Paris-Sud
Brad Joliff Overview speaker /Washington University in St. Louis
Veronica Oliveros Junior keynote speaker /Departamento Ciencias de la Tierra, Universidad de Concepción, Concepción, Chile

This theme deals with the Big Picture: where and when do granites and related rocks form? What controls their differences between various sites on our planet, or indeed between planets? How did granite magmatism evolve in time, and how does it impact the nature and evolution of the continental crust?
