AbstractMost of the Tyrrhenian basin has formed by extension of the upper-plate continental lithosphere in a subduction-zone geodynamic setting, in a process fundamentally driven by the migration of a Ionian oceanic slab across the mantle. The amount of extension abruptly changes from north to south. In the north east of Corsica rifting stopped after low extension factor. Towards the south extension increased up to full crustal separation that was followed by mantle exhumation, and locally collocated large-scale volcanism. We use 5 transects across the basin with coincident wide-angle seismic data and multichannel seismic images to analyze the changes in the tectonic and crustal structure with increasing amount of extension. Thus, the basin is a unique location to investigate a full rift system with one survey
