Abstract

The Ligurian Sea opened ~ 30–15 Ma during the SE migration of the Calabrian subduction zone. The extension of the continental lithosphere led to extreme crustal thinning and mantle exhumation in the Ligurian Basin. Seismic travel time tomography reveals the absence of oceanic crust, documenting that extension of the basin stopped before seafloor spreading was initiated. Our new interpretation on the nature of the crust is important for plate reconstruction modeling related to the Alpine orogen.
