             abstract = "Late Quaternary deposits in the northeastern Brazil have been 
                         scarcely investigated, despite their relevance to the discussion 
                         of the post-rift evolution of the South American passive margin 
                         within the context of landform, sea level and tectonic 
                         deformation. Sedimentological, stratigraphic and morphological 
                         characterization of these deposits, referred as Post-Barreiras 
                         Sediments, led to their distinction from underlying Early/Middle 
                         Miocene strata. Based on optically stimulated luminescence (OSL) 
                         dating, two sedimentary units (PB1 and PB2) were recognized and 
                         related to the time intervals between 74.8 +/- 9.3 and 30.8 +/- 
                         6.9 ka, and 8.8 +/- 0.9 and 1.8 +/- 0.2 ka, respectively. Unit PB1 
                         consists of indurated sandstones and breccias either with massive 
                         bedding or complex types of soft sediment deformation structures 
                         generated by contemporaneous seismic activity. Unit PB2 is 
                         composed of massive sands or sands related to structures developed 
                         by dissipation of dunes. The present work, focusing on the 
                         Post-Barreiras Sediments, discusses landform, sea level and 
                         tectonics of the eastern South American passive margin during the 
                         latest Quaternary. Non-deposition and sub-aerial exposure related 
                         to the Tortonian worldwide low sea level combined with tectonic 
                         quiescence followed the Miocene transgression. Tectonic 
                         deformation in the latest Pleistocene created space to accommodate 
                         unit PB1 in downthrown faulted blocks and, perhaps, also synclines 
                         produced by strike-slip deformation. Although deposition of this 
                         unit was simultaneous with the progressive fall in sea level that 
                         followed the Last Interglacial Maximum, punctuated rises combined 
                         with land subsidence led to marine deposition close to the modern 
                         coastline. Renewed subsidence in the Holocene gave rise to 
                         accommodation of the Post-Barreiras Sediments. Most of unit PB2 
                         was deposited during the Holocene Transgression, but it is not 
                         composed of marine sediments, which suggests either an 
                         insignificant rise in relative sea level or aeolian reworking of 
                         thin transgressive sands. The data presented here lead to a review 
                         of the evolution of the South American passive margin based on 
                         assumptions of uniform sedimentation and undeformed planation 
                         surfaces over a wide coastal area of the northeastern Brazil. (C)
