“…The most important source of recent sediments to the southwestern Atlantic shelf is the La Plata River plume, whose sedimentary influence can be recognized up to 25°S (Mahiques et al, 2008). In the northeastern sector, recent sediments are mainly derived by the many small rivers located in the São Sebastião, Caraguatatuba, and Ubatuba cities (Vieira et al, 2018).…”

“…In this area (Area 2) the mud contents are higher than in the southwestern inner shelf, as the wedge is mainly composed of medium-to-coarse silts. Such deposit was interpreted as a non-deltaic clinoform wedge, partially fed from the combined input of several small rivers (Vieira et al, 2018).…”

“…Assim, pode-se inferir que a origem relíquia da cobertura sedimentar arenosa da área investigada neste trabalho está diretamente associada à escassez de expressivos fluxos fluviais. Ao analisar as descargas fluviais ao longo da plataforma continental paulista, tem-se que o rio Iguape e o rio Juqueriquerê, ambos localizados fora da área de estudo e considerados como os principais rios locais, apresentam vazões de aproximadamente 435,0 e 2,79 m 3 •s -1 , respectivamente (Mahiques et al, 1999;Vieira et al, 2018). Esses valores são muito baixos quando comparados com alguns outros rios que desaguam na costa sul americana, como o rio Paraíba do Sul (1.130 m 3 •s -1 ) e o rio da Prata (25.000 m 3 •s -1 ) (Guerrero et al, 1997;Luiz e Oliveira, 2017).…”

“…Os depósitos lamosos identificados junto às zonas de deposição de lama são sedimentologicamente caracterizados por uma mistura entre areia, silte e argila. No geral, tem-se que essa mistura sedimentar é comumente encontrada na maioria dos depósitos lamosos já identificados ao longo das plataformas continentais mundiais (Nitrrouer et al, 1986;Hanebuth e Lantzsch, 2008;Liu et al, 2014;Vieira et al, 2018).…”
