             abstract = "The relief evolution of several areas of northeastern Brazil has 
                         been increasingly related to tectonic events. This is the case for 
                         the Paraiba Basin, where an abundance of faults and folds were 
                         recorded in Neogene and even Late Pleistocene-Holocene deposits. 
                         We tested whether dome-like morphologies in the northern sector of 
                         this basin, where geological exposures are scarce, were also 
                         formed by tectonic deformation. The work combined limited 
                         geological data with qualitative and quantitative analyses of the 
                         relief applying the 1 arc-second digital elevation model provided 
                         by the Shuttle Radar Topography Mission. The geomorphic indices of 
                         basin asymmetry factor (AF), swath topographic profiles, enhanced 
                         transverse hypsometry index (THi*) and normalized river 
                         long-profiles were used for validating a neotectonic origin for 
                         the dome-like morphologies. This interpretation was also supported 
                         by other morphological evidence of the dome relief, including: 
                         recurving channels featured in radial to recurved trellis 
                         patterns; tectonically-controlled drainage sub-basins; high 
                         relative relief values related to increased fluvial incision; and 
                         anomalous river long-profiles indicative of ungraded rivers. The 
                         domic structures were attributed to fault- and fold-related 
                         strike-slip deformation during the late Quaternary. This record 
                         supports the proposal that the South American passive margin 
                         remained under tectonic stress long after the main rifting in the 
                         late Jurassic-early Cretaceous.",
