Short Curriculum Vitae

I investigate the petrological processes controlling the evolution of magmas during fractional crystallization, magma assimilation, and mixing. I also interpret the geochemical changes generated by variable undercooling regimes experienced by magmas during their emplacement. Magmas follow diverse polybaric, multicomponent, and multiprocess evolution paths. Major and trace element concentrations of mineral and residual glasses may be controlled by disequilibrium growth processes that take place during magma ascent and emplacement. Crystals may grow rapidly, and in the process, may deviate from equilibrium, even if the mineral is indeed contained within the liquid from which it grew. By means of experimental and field observations, my researches focus on the compositional variations of minerals growth under variable cooling rate conditions. I compare such disequilibrium compositions with those of crystals equilibrated at isothermal temperatures in order to improve the predictive power of thermometers, barometers, and hygrometers. Upon the effect of fast undercoolings, the growing crystals may potentially record the closure P-T-X-fO2 conditions of the system. This opens new important perspectives in the interpretation of the petrochemical characteristics of igneous rocks, allowing to reconstruction the history of volcanic rocks through geospeedometers based on the kinetics of cation exchanges between crystal and melt.
