The basins of the Calabria Arc, important constraints for the dynamics of the Tyrrhenian opening.

The Calabrian Arc is the only segment of the Apennine chain that has recorded the entire history of the geological evolution of the Mediterranean. In addition to the first Mesozoic rifts, it recorded Alpine subduction and the subsequent formation of the present Mediterranean basin. The oldest successions, attributable to the opening of the Tyrrhenian Sea, start from the Serravallian stage and fill increasingly recent basins which, in addition to the timing, well record the direction of Tyrrhenian extensions. These data provide the essential elements to outline the dynamics of the opening of the Tyrrhenian Sea and the contemporary formation of the Apennine chain. The main stratigraphic records, regional scale structural maps and the kinematic extension model will be shown to outline the constraints for the dynamics of the Tyrrhenian opening and its correlation with the Calabrian Arc, with the main objective of achieving a more complete knowledge of this portion of the Mediterranean area.
