Abstract | Estudos realizados em diferentes contextos geomorfológicos da Terra têm demonstrado a eficácia da aplicação de dados geomorfométricos extraídos a partir de modelos digitais de elevação para a identificação de feições do terreno sugestivas de deformação tectônica. Este estudo aplica índices geomorfométricos na avaliação da intensidade tectônica de depósitos sedimentares da porção emersa da Bacia Paraíba e do embasamento cristalino adjacente, nordeste do Brasil. A partir da base digital da rede de drenagem e do modelo digital de elevação da Shuttle Radar Topography Mission (SRTM) foram empregados os índices: relação declividade-extensão (RDE), fator assimétrico (Af), integral hipsométrica (Hi) e sinuosidade de frente de montanha (Smf). Os resultados possibilitaram distinguir e espacializar classes de intensidade de deformação tectônica por meio do índice de atividade tectônica relativa (Iat). Os dados revelaram tectonismo mais intenso em unidades sedimentares neógenas e quaternárias localizadas na porção nordeste da área estudada. ABSTRACT: Spatialization of tectonic intensity in the onshore portion of the Paraíba Basin and adjacent crystalline basement, Northeastern Brazil. Studies conducted in different geomorphological contexts of the Earth have demonstrated efficiency in the application of geomorphometric data extracted from digital elevation models for the identification of terrain features suggestive of tectonic deformation. This study applies geomorphometric indices for the evaluation of the tectonic intensity of sedimentary deposits of the onshore portion of the Paraíba Basin and of the adjacent crystalline basement, northeastern Brazil. The following indices were applied with basis on digital drainage network and digital elevation model of the Shuttle Radar Topography Mission (SRTM): slope-length ratio (SL), asymmetric factor (Af), hypsometric integral (Hi) and mountain- front sinuosity (Smf). The results enabled to distinguish and to spacialize classes of tectonic deformation intensity through the tectonic intensity index (Iat). The data revealed more intense tectonism in Neogene and Quaternary sedimentary units located in the northeastern portion of the study area. |
