Intraplate Compression Across South America: A Key Element For Basement-Involved Meso-Cenozoic Tectonics Of Brazilian Marginal Basins

Examples are briefly given of at least 2 events of<br>post-rifting tectonic inversion in the Potiguar and in<br>the Almada basins. The discussion of these examples<br>within the frame of the Meso-Cenozoic tectonics of<br>the South America plate leads to the conclusion that<br>the paradigm following which post-rift deformation<br>of the Brazilian margin basins are solely controlled<br>by thin-skinned gravitational tectonics should be<br>abandoned. As a corollary, it is proposed that<br>basement-involved compressional tectonics should<br>play an important role in the deformational history if<br>these basins.
