             abstract = "The post-rift tectono-sedimentary history of passive margins has 
                         been an issue of increased interest after the perception of their 
                         unsteady nature during the Neogene and Quaternary. The evolution 
                         of the eastern South America margin might be benefited from 
                         investigations of the sedimentary record in a number of marginal 
                         basins. The Para{\'{\i}}ba Basin is of particular interest to 
                         discuss the post-rift evolution of the South American passive 
                         margin, because it represents the last bridge with the African 
                         plate. This work aims to analyze the post-rift sedimentary record 
                         of the onshore Para{\'{\i}}ba Basin as a contribution to discuss 
                         the neotectonic history of the South American passive margin. 
                         Surface and subsurface data were integrated from outcrops, deep 
                         stratigraphic profiles, airborne geophysical maps and remote 
                         sensing products. The depositional and denudational processes in 
                         this basin were a result of tectonic subsidence and uplifting. 
                         Tectonics after the main rifting phase are indicated by abundant 
                         structures, including normal, reverse, and strikeslip faults, as 
                         well as folds that affected the Neogene and Late Pleistocene 
                         sedimentary deposits. The ductile and brittle deformation resulted 
                         mainly from multiple reactivations of EW, NESW and NWSE trending 
                         basement shear zones. The deformation mechanism included 
                         distension and compression under a strikeslip regime. Tectonic 
                         reactivations even during the late Pleistocene support an unsteady 
                         South Atlantic passive continental margin throughout the 
                         postrifting stage.",
