Palaeomagnetic Evidence for Rotation of Sardinia during the Early Miocene

GEOLOGICAL and palaeomagnetic evidence indicates that after the Permian the Corso–Sardinian plate rotated counterclockwise with respect to stable (extra-Alpine) Europe1–6. Palaeomagnetic directions from Late Oligocene/Early Miocene rocks can be interpreted as indications for a Late Tertiary rotation5,7. Here we present additional palaeomagnetic data from volcanic rocks and tuffites of Tertiary age, collected near the village of Castelsardo on the northern coast of Sardinia (Fig. 1).
