Palaeomagnetic data for the upper Palaezoic and, in particular, the Devonian of South America are still very limited and therefore polar wandering curves cannot be established. We investigated the paleomagnetism of 43 stratigraphic horizons of the Upper Devonian Longá Formation. The results should make a contribution towards a better definition of that curve. Sampling was done according to the block method in profiles on highway PI-13 between Teresina, Barras and Batalha, and on highways PI-24 and BR-230 between Floriano, Nazaré do Piauí and Oeiras, all in the state of Piauí. Investigations were carried out at the "Laboratório de Paleomagnetismo" of the University of São Paulo and completed at the laboratory of the NCGG of the Federal Unive...
