                         fabric in the tectono-sedimentary and geomorphological evolution 
                         of the Para{\'{\i}}ba Basin, continental margin of northeastern 
                         Brazil, during the Cretaceous, Neogene, and Quaternary. This basin 
                         represents part of the last bridge between South America and 
                         Africa before the last breakup stage of the South Atlantic rifting 
                         in the early Cretaceous. The Para{\'{\i}}ba Basin infill is 
                         composed of siliciclastic and carbonate Cretaceous units, as well 
                         as aeolian, fluvial and marine Quaternary units. We used shuttle 
                         radar imagery, aeromagnetic, wellbore and field data. The 
                         reduced-to-the-pole magnetic map (RTP) indicates the continuity of 
                         the steeply dipping Precambrian basement shear zones beneath the 
                         Para{\'{\i}}ba Basin. The combined analysis of surface and 
                         subsurface data shows that NE-SW and E-W-striking shear zones were 
                         subjected to brittle reactivation in the Aptian-Middle Albian 
                         during the basin opening and again in the Neogene-Quaternary, 
                         forming a system of horsts and grabens along the basin; some of 
                         these structures such as the E-W-oriented Pernambuco shear zone 
                         present modern-day seismicity. N-S- and mainly NW-SE-striking 
                         transfer faults cut across Aptian-Middle Albian to 
                         Neogene-Quaternary strata. These four main fault directions 
                         control main river channels and alluvial valleys up to 2 km wide. 
                         Topographic breaks up to 50 m were created by late reactivation of 
                         rift faults, which mark the boundary between horsts and grabens 
                         along the basin. In addition, structural data evidence 
                         syn-tectonic faulting with vertical offsets up to 80 m in the 
                         Cretaceous and up to 70 m in the Neogene-Quaternary. We conclude 
                         that shear zones across the study area are long-lived structures 
                         that have behaved as weakness zones. Their neotectonic brittle 
                         reactivation has controlled sediment deposition and landform 
                         development, which continued through the Neogene-Quaternary.",
