Definition and dating of the Venaco Formation (Corsica, France) A Priabonian gravity flow deposit
Résumé
Priabonian age is highlighted for the first time in Corsica in the Venaco Formation using the presence of specific microfauna (in particular some representatives of Turborotalia cerroazulensis lineage) This silicoclastic formation is mainly represented by coarse facies It is composed of three members from south to north and from oldest towards youngest member of Uboli Cardo and Oisu The sedimentologic analysis reveals a gravity depositional environment involving different type of currents Sedimentologic and chronologic characteristics make the Venaco Formation and the Annot Formation (p p) equivalent Dating the Venaco Fm brings confirmation that the green schist metamorphism of the Variscan batholith and the related deformation are from the pre-Priabonian period
