The research is focused on the petrogenetic processes that characterize the mid-to deep Earth’s crust, where metamorphic and igneous rocks predominate. We aim at understanding the temperature and pressure (depth) conditions at which rocks transform by metamorphic reworking, and the mechanisms of crustal anatexis responsible for the formation of anatectic granitic magmas and their geochemical diversification. These studies also characterize the extreme metamorphic conditions that may occur in the crust at ultra-high pressure or temperature conditions.

The multidisciplinary approach includes fieldwork, the microstructural and petrographic analysis of rocks, the full microchemical characterization of minerals, melts and fluids, the thermodynamic and geochemical modelling and the experimental simulation of phase equilibria, and dating of metamorphic and igneous events.

The research, undertaken in collaboration with experts in the fields of structural geology, mineralogy, geochemistry and tectonics, utilizes the state-of-the-art analytical and computational techniques. The topic of crustal anatexis and origin of granites is also approached through the innovative and original studies of fluid and melt inclusions in peritectic minerals from migmatites and granulites, of which the Department is world-renowned leader.
