Abstract
An apatite fission track thermochronological survey of Corsica was undertak en in order to decipher its Cenozoic thermo-tectonic evolution. A remarkabl e geographic zoning of FT ages with a gradient from southwest (older ages) to northwest (younger ones) is interpreted as the result of two major cooli ng steps, respectively dated at 26-20 Ma and 18-10 Ma. These coolings are a ttributed to exhumation phases associated with the Oligo-Miocene Liguro-Pro vencal rifting and the Miocene Tyrrhenian extension, respectively.
