Notes:
We propose a thermo-mechanical model and a new interpretation of heat flux data for the Ligurian basin that may be a key to understanding the evolution of the NW Mediterranean. The model incorporates the removal of a portion of mantle lithosphere to explain the heat-flux and subsidence anomaly of the eastern (Corsican) margin of the basin. This process is envisaged as a result of eastward asthenosphere flow induced by the Apennines subduction system. After a heating phase, time-dependent conductive cooling and re-thickening of the lithosphere result in re-equilibrium of the thermal gradient to its initial value. Such a rifting mode can account for the asymmetric heat-flux and subsidence pattern observed across the basin and the present-day lithospheric thickness.
