Dérive Cénozoique de la corse et de la Sardaigne et ses merqueurs géologiques

Abstract

Drifting in a southeastern direction of Corsica and Sardinia was the major feature during the recent evolution of the northwestern Mediterranean basin. The reality of this phenomenon is demonstrated by geological and geophysical data. Furthermore, values of palaeomagnetic declinations, ocean continent limits and linear geological markers, lead to a reconstruction of the pre-drifting Cenozoic position of the two islands with respect to the European margin. Finally, the age and kinetic system of drifting are defined with the help of the significance, age and palaéomagnétic characteristics of calc-alkaline Cenozoïc volcanism of Sardinia.
