U-Pb and Sm-Nd data of the Rhyacian and Statherian Orthogneisses from Rio Piranhas-Seridó and Jaguaribeano Terranes, Borborema Province, Northeast of Brazil

The Portalegre shear zone separates the Rio Piranhas-Seridó and the Jaguaribeano geological terranes in the Northern Domain of the Borborema Province. Banded gneisses of the Caicó and the Jaguaretama Complexes represent the basements of these terranes. U-Pb analyses yielded ages of 2,193 ± 16 Ma f...
