Low-Angle Normal Faults (LANFs) represent in the central Southern Alps area (N Italy) main structures along which Variscan basement is contact with Upper Carboniferous-Permian volcanic-sedimentary succession. Tourmalinites frequently occur LANFs, usually replacing former cataclasites. The mineralogy and chemical composition of tourmalinites point to a metasomatic origin. together high-angle fau...

Subduction of oceanic crust buries an average thickness 300–500 m sediment that eventually dehydrates or partially melts. Progressive release fluid/melt metasomatizes the fore-arc mantle, forming serpentinite at low temperatures and phlogopite-bearing pyroxenite where slab surface reaches 700–900 °C. This is sufficiently high to melt subducted sediments before they approach depths arc magmas ar...
