             abstract = "Quaternary post-Barreiras sediments are widespread along Brazil's 
                         passive margin. These deposits are well exposed in the onshore 
                         Paraiba Basin, which is one of the rift basins formed during the 
                         Pangean continental break-up. In this area, the post-Barreiras 
                         sediments consist of sandstones with abundant soft-sediment 
                         deformation structures related to seismicity contemporaneous with 
                         deposition. The trace fossils Thalassinoides and Psilonichnus are 
                         found up to 38 m above modern sea level in sandstones dated 
                         between 60.0 (+/- 1.4) and 15.1 (+/- 1.8) ka. The integration of 
                         ichnological and sedimentary facies suggests nearshore 
                         paleoenvironments. Such deposits could not be related to eustatic 
                         sea-level rise, as this time coincides with the last glaciation. 
                         Hence, an uplift of 0.63 mm/yr, or 1.97 mm/yr if sea level was 80 
                         m lower in the last glaciation, would have been required to ascend 
                         the post-Barreiras sediments several meters above the present-day 
                         sea level during the last 60 ka. This would suggest that the 
                         post-rift stage of the South American eastern passive margin may 
                         have experienced tectonic reactivation more intense than generally 
                         recognized. Although more complete data are still needed, the 
                         information presented herein may play an important role in studies 
                         aiming to decipher the Quaternary evolution of this passive 
                         margin.",
