Al- and F-rich titanite (3.86< Al2O3 < 9.33 wt%, 0.93< F < 2.53 wt%) from a polymetamorphic marble of the Sesia Zone (Western Alps) has been investigated in order to determine the behaviour of titanite during high-pressure metamorphism. Meso-structural to micro-structural relationships, mineral assemblages and petrological data indicate a pre-Alpine (low-pressure, high-temperature) to early-Alpine (high-pressure, medium-temperature) pressure-temperature-time evolution.
