Palaeomagnetism of Jurassic and Cretaceous rocks from South America and the tectonics of the central Andes
Paleomagnetic data for Jurassic and Cretaceous rocks from the South American and Patagonian platforms and the Andean chain were recomputed or reevaluated. The reliable data for Lower and Upper Cretaceous rocks from the Andean Chain for sampling sites situated north of Arica do not support the abrupt...
