abstract = "There has been increased publications focusing tectonic structures
in Neogene and Quaternary deposits of northeastern Brazil, despite
its localization in the South American passive margin. Faults and
folds are particularly abundant in deposits of these ages exposed
in the central and southern parts of Para{\'{\i}}ba Basin. In
contrast, an overall scarcity of outcrops has precluded
investigation of the northern part of this basin, but this work
shows that this area also displays a tectonically-controlled
relief. The survey consisted in integrating morphostructural
analysis, transverse topographic symmetry factor (TTSF) index and
a few geological data aiming to test the tectonic influence in
this area and investigate both the extent and styles of
deformation. Our data derived from the digital elevation model
(DEM) of the Shuttle Radar Topography Mission (SRTM), as well as
existing cartographic data and geological information derived from
outcrops and drills. The results revealed: anomalous drainage
patterns, such as trellis and associated subtypes; abrupt channel
inflections forming obtuse to right angles; compressed and
isolated meanders; and morphostructural lineaments with trends
compatible with regional tectonic structures of northeastern
Brazil. In addition, the TTSF index was efficient to evidence
tectonically-controlled asymmetrical sub-basins on Late
Pleistocene-Holocene sedimentary deposits. This work also revealed
a dome-like structure related to an anticline in the central part
of the study area. We concluded that the relief of northern
Para{\'{\i}}ba Basin reflects faults and folds formed by
extension and compression within a strike-slip regime, evidencing
the relevance of tectonic reactivation during a relatively recent
evolution (i. e., Late Pleistocene-Holocene) of the South American
passive margin.",
