We applied thermal demagnetization to 12 sites of mid- and Upper Cretaceous volcanics and sediments of the Zaza terrane (central Cuba). Consistent directions of low- and/or high-temperature components were obtained from eight sites. The fold test performed on a short-wave fold in the Upper Cretaceous Arimao Formation is negative, as well as the conglomerate test on lava boulders from the same formation, whereas site-means for the entire data set are better grouped after tilt-correction. We conclude that the entire Cretaceous succession of the Zaza terrane was remagnetized in the Campanian. The measured latitude is lower by 15¿¿6¿ with respect to the North American APWP indicating ca. 1600¿600 km northward displacement of the Zaza terrane since the Campanian. Also discordant is the measured declination implying 37¿¿11¿ counterclockwise rotation of the Zaza terrane. ¿ American Geophysical Union 1994 We applied thermal demagnetization to 12 sites of mid- and Upper Cretaceous volcanics and sediments of the Zaza terrane (central Cuba).
