Quaternary Tectonic Reactivation in the Southern Domain of Borborema Province, NE Brazil: Integration of Morphometric, Geological and Geophysical Data From the Una River Drainage Basin

Abstract: ResumoIntegração de dados em diferentes escalas foi realizada com o objetivo de identificar possíveis efeitos de reativações tectônicas cenozoicas (pós-rifte), relacionadas ao embasamento adjacente à Bacia Pernambuco, sobre o qual está localizada a bacia hidrográfica do Rio Una. O estudo foi baseado na integração de parâmetros morfométricos do canal do Rio Una, modelados a partir de imagens de radar, dados de geologia de superfície e dados de sísmica de reflexão multicanal 2D adquiridos no canal do rio, próxim… Show more

“…The surface sediments of the SPCS comprise biogenic carbonate sediments, comprising mostly sand, gravel, and bioclasts, resulting from the remains of calcareous algae (Kempf, 1970;Manso et al, 2003Manso et al, , 2004Camargo et al, 2015). Neotectonic activity has significantly impacted the shelf domain and coastal zone of the Pernambuco Marginal Basin (Correia Filho et al, 2019). This activity has led to a range of geomorphological features influenced by faults and fractures, including those found in the Quaternary Barreiras Formation, as reported by Bezerra et al (2014).…”

“…Of these features, the most notable are the numerous active and ancient faults that have altered the elevation and orientation of the sedimentary strata in the basin (Rossetti et al, 2011;Gandini et al, 2014;Souza et al, 2022). The reactivation of basement-seated faults created current structures, such as river valleys and fluvial terraces in the coastal zone, which can be observed from fault scarps formed by displacement along the fault line (Peulvast et al, 2006;Bezerra et al, 2014;Peulvast and Bétard, 2015;Correia Filho et al, 2019;Bezerra, 2020a, 2020b;Matos et al, 2021).…”
