The importance of serpentinite mylonites for subduction and exhumation of oceanic crust.

Hermann, Joerg; Muntener, Othmar; Scambelluri, Marco

Description

In the ultramatic Erro-Tobbio unit (Voltri-Massif: Western Alps) a set of overprinting structures in serpentinite mylonites is related to Alpine subduction to about 80 km depth and to subsequent exhumation. Antigorite mylonites are cut by en-echelon olivine veins, which in turn are dissected by multiple sets of shear bands containing olivine and titanian clinohumite. The transition from olivine-free to olivine-bearing structures indicates recrystallization during prograde metamorphism. All...[Show more]
