Quaternary fault control on the coastal sedimentation and morphology of the São Francisco coastal plain, Brazil

Late Pleistocene–Holocene evolution of the Doce River delta, southeastern Brazil: Implications for the understanding of wave-influenced deltas

“…Sea-level fluctuation has been suggested as an important factor to have influenced the evolution of the Brazilian deltas (e.g., Dominguez, 1996). However, a recent publication (i.e., Lima et al, 2014) showed that the morphology and sedimentary deposition of the São Francisco delta were controlled by N-S to NE-SW trending normal faults reactivated in the Quaternary, which might have also been the instance of many other areas of the Brazilian margin (see also Nogueira et al, 2010;Bezerra et al, 2014;Rossetti et al, 2011Rossetti et al, , 2013. Previous publications (e.g., Hatushika et al, 2007;Bricalli and Mello, 2013) have also suggested that the evolution of the Doce River delta was controlled by tectonic activity contemporaneous to sediment deposition.…”

Structural Control of the São Francisco River Delta from the Aeromagnetic Data, Brazil

“…3 it is possible to verify the Cretaceous faults with a parallel orientation to the internal boundary of the delta plain plunging toward the basin. Lima et al [13] also presented evidence of other reactivations during the Pleistocene-Holocene that affected or created additional accommodation space for the deposition of the other units. The Fig.…”

“…Armstrong et al [11] developed a study that shows the influence of the presence of reactivated growth faults in the Mississippi Delta, and Stanley [12] developed a study that attempted to understand subsidence processes in the Nile Delta, where he concluded that subsidence rates were accelerated due to the neotectonic present in the region. Finally, LIMA et al [13] researched the São Francisco Delta that focused on the study of the reactivation of faults in the Quaternary as the main controlling agent of sediment deposition and morphology of this delta.…”

“…In a more recent work, Lima et al [13] researched the DSF that had as main focus the process of reactivation of faults in the Quaternary, considered by the author as the main controlling agent of sediment deposition and delta morphology. This control would occur from the generation of new space for sediment accommodation, through the reactivation of faults.…”
