Caracterização geomorfológica e tectônica da carta Conde 1:25.000.

Abstract

This present work aims to present tectonic evidences in which acted in the configuration of the relief comprising the delimitations of the Conde chart 1:25.000 (SB.25-Y-C-III-3-NO), this analysis was possible through thematic maps (hypsometric and slope) and the Digital Terrain Model (DTM), generated from the vectorization of the topographic abovementioned chart. The comprised area, is located on the eastern edge of the Paraíba state in Brazilian northeast, which is superimposed in the coastal trays. During this research will be exposed some morphotectonic and fluviometric analysis (Relation Declivity Extension - RDE), in order to have more detailed informations about which processes have influenced the current drainage, such parameters were applied in a tributary of Mamuaba river basin, two other in Gramame river tributaries, in the main riverbeds of Aterro and da Salsa rivers, presenting some peculiar characteristics in sedimentary rocks, possibly due of neotectonic reactivations. Besides of revealing structural patterns (asymmetry, straightness and inflections) and drainage forms of rivers and streams.
