Abstract
A paleomagnetic study carried out in the Cretaceous Matasiete and Castillo formations which outcrop in the San Bernardo fold belt (central Patagonia) gave a paleopole position: MCPP= Lat. 66.S, Long, 9·E. The correlation of this PP position with a coeval PP position from the extraandean Patagonia shows a counter-clockwise rotation about a vertical axis of the MCPP site. The rotation is in agreement with structural features present in this area.
