RESUMO:

The Barreiras Formation is a terrigenous sedimentary cover that occurs almost continuously on the Brazilian coast and is distributed from the state of Amapá to Rio de Janeiro. The present work has the objective of identifying the main deformational structures present in the sediments of the Barreiras Formation on the northeast coast of Bahia. As a specific objective we have: i) to draw the structural lineaments in satellite image ii) to compare the field data with the data obtained in satellite image ii) to determine the structural inheritance of the basement iii) to integrate the data and to propose a neotectonic model . The research area is located on the northeast coast of the State of Bahia between the municipalities of Camaçari and the extreme south of the State of Sergipe. Because it is a densely populated area and home to several real estate projects, it is of fundamental importance to study the tectonic and deformation aspects of this unit. It is located in the context of the São Francisco Craton and includes part of the crystalline basement, Archaean / Paleoproterozoic Domain, represented by the northern segment of the Salvador Esplanada Boquim Orogen, the Recôncavo Basin and the Neogene / Quaternary Domain, represented by the Barreiras and Post-Barreiras Formation . The lineaments obtained in the basement have a preferred direction of N040 ° / 050 °, N60 ° / 070 °, 150 ° / 160 °, and the Paleozoic / Mesozoic Lineaments have the N040 ° / 050 °, N100 ° / 110 N110 ° / 120 °, and the Neogene Domain has standards ranging from N070 ° / 080 °, N100 ° / 110 ° and N030 ° / 040 °. The data obtained in the field of failure and fracture of the Fm. Barriers vary between N40 ° / 050 °, N060 ° / 070 ° compared to the structures of the other units, there was a repetition between the structures, which reinforces the idea of reactivation of preexisting faults and generation of new structures in the Fm. Barriers and measurements of the ductile and ductile / plastic field structures present Orthorhombic patterns typically neotectonic.
