A reativa??o das estruturas do embasamento pr?-cambriano, ap?s a separa??o entre a Am?rica do Sul e ?frica no Cret?ceo, teve um papel importante na evolu??o de suas bacias, o que proporcionou formas de relevo variadas. Estas caracter?sticas morfodin?micas podem ser facilmente percebidas nos sedimentos de borda das bacias marginais, que apresentam fortes ind?cios dessas reativa??es. O objetivo deste trabalho ? investigar a influ?ncia dos processos morfotect?nicos na estrutura??o da paisagem nos sedimentos da Bacia Para?ba. Para tanto foram utilizados dados aeromagn?ticos de alta resolu??o, imagens da Shuttle Radar TopographicMission-SRTM, dados geol?gicos estruturais, dados de po?os profundos e dados geol?gicos de campo. Nos resultados foi observado que algumas estruturas conhecidas no embasamento da Bacia Para?ba coincidem com os lineamentos magn?ticos e topogr?ficos interpretados como reativa??es de falhas do P?s-Mioceno. A atividade neotect?nica ocorrida na Bacia Para?ba teve a capacidade de reorganizar a deposi??o dos sedimentos e de dominar os padr?es das formas de relevo. Dados estruturais adquiridos nas unidades litoestratigr?ficas mostram evid?ncias de atividade tect?nica associada ? deposi??o e eros?o de sedimentos do final do Cret?ceo at? o presente. Isto indica que a deposi??o dos sedimentos p?s-cret?ceos foi influenciada por reativa??es de estruturas do embasamento pr?-cambriano nesta por??o da margem continental brasileira. / Recent endogenous processes provide dynamic movements in the lithosphere and generate the varied forms of relief, even in areas of passive continental margins, such as the research area of this work located in northeastern Brazil. The reactivation of Precambrian basement structures, after the breakup between South America and Africa in the Cretaceous played an important role in the evolution of basins, which provided generated forms of relief. These morphodynamic characteristics can be easily observed in marginal basins that exhibit strong evidence fault reactivations. The purpose of this study is to investigate the influence of morphotectonic processes in the landscape structuring of Para?ba Basin. Therefore, we used aeromagnetic, high?resolution images of the Shuttle Radar Topographic Mission?SRTM, structural geological data, deep well data and geological field data. Based on the results of the data was observed that some preexisting structures in the crystalline basement coincide with magnetic and topographic lineaments interpreted as fault reactivation of the Post?Miocene units in the Para?ba Basin. Faults that offset lithostratigraphic units provided evidence that tectonic activity associated with the deposition and erosion in the Para?ba Basin occurred from Cretaceous to the Quaternary. The neotectonic activity that occurred in Para?ba Basin was able to influence the deposition of sedimentary units and landforms. It indicates that the deposition of post?Cretaceous units was influenced by reactivation of Precambrian basement structures in this part of the Brazilian continental margin.
