There were several phases of Alpine metamorphism in the Vanoise region of Savoy, France. Certain early-formed minerals (garnet, glaucophane, and lawsonite) were unstable in the later metamorphic phases. Only pseudomorphs after lawsonite remain. Lawsonite is considered to have been abundantly developed in the initial stages of metamorphism, probably at shallower depth than the zone with epidote and garnet. The glaucophane-lawsonite subfacies thus existed in the upper Maurienne as in other regions that were subjected to Alpine orogenesis and metamorphism.
