We report the first evidence of fault rocks developed during high-pressure/low temperature subduction-related metamorphism, within quartz+epidote pods embedded in the glaucophane-lawsonite-bearing ophiolitic metabasalts of the Diamante-Terranova unit (Calabria, Italy). Fault rocks occur as relic inj...
