                         trending structure in the Barreirinhas Basin, one of the several 
                         Brazilian coastal basins. This lineament splits the study area in 
                         two sectors of distinctive morphology, drainage patterns, and 
                         sedimentary covers. Terrain northward of the lineament presents a 
                         smooth topography with sub-parallel to sub-dendritic drainage 
                         patterns, whereas a dissected plateau characterized by incised 
                         valleys and rectangular drainage pattern occurs southward, 
                         suggesting a structural control by joints and faults. Geological 
                         field data, crossed with thermal luminescence (TL) and optically 
                         stimulated luminescence (OSL) dating, revealed that the surface 
                         southward of the lineament consists mostly of Miocene and late 
                         Pleistocene sedimentary deposits, represented by the Barreiras 
                         Formation and the Post-Barreiras sediments, respectively. In 
                         contrast, relatively younger sands mantle most of the northward 
                         terrain, as indicated by well-preserved paleodune deposits that 
                         grade into active aeolian dunes of the Lencois Maranhenses 
                         National Park. Geomorphological and geological data analysis 
                         suggests that the northern sector is under the effect of 
                         subsidence, proving that the Pirapemas Lineament is an active 
                         agent modeling the landscape in the region. Geophysical data 
                         (gravity and seismic) confirm that such a structural feature is 
                         the surface expression of an active deep-seated basement fault.",
