Abstract

The project proposes to investigate the magmatic evolution of an intrusive body (Limeira Gabbro) from the Magmatic Province of Paraná, with emphasis on the identification of liquid immiscibility processes, by integrating structural and geochemical studies of minerals, rocks and "melt inclusions" (including trace-elements and volatiles).
