Summary:An Sm-Nd age of 747 ± 120 Ma for amphibolite interbedded in a succession of micaschist using whole rock and mineral samples, and of a minimum of 476±26 Ma for the overlying conglomerate by evaporation of Pb on monozircon, support the hypothesis for the presence of a Panafrican basement in the northwest of Corsica.
