Caracterização das fontes dos sedimentos marinhos da Plataforma Continental da região sudeste do Brasil, durante o Holoceno médio e superior com base na composição isotópica de Sr, Nb e Pb: implicações nos estudos paleoclimáticos e de hidrodinâmica marinha

Abstract: AGRADECIMENTOSAgradeço a meus pais biológicos Suely Sandra Torquato Sonvesso e Pedro Geraldo Sonvesso; ao meu orientador Colombo Celso Gaeta Tassinari; coorientador Michel Michaelovitch de Mahiques, quem pude contar com sua colaboração e ensinamentos desde quando iniciei meu Mestrado no Instituto Oceanográfico; a todos os professores do Instituto de Geociências, pelo ensinamento de disciplina, responsabilidade, dignidade, trabalho e diligência. Agradeço de coração a todos os colegas, alunos e funcionários do I… Show more

“…The compilation has included isotopic data from marine and river sediments related to the evaluated continental rocks: (A) ε Nd(0) data of superficial sediments from the Rio de La Plata estuary and Argentinian shelf (Basile et al, 1997;de Mahiques et al, 2008); (B) Nd data associated with eroded rocks of Coastal Domain of the Ribeira belt; (C) Nd radiogenic isotope signatures of Paraíba do Sul River suspended load (Roig et al, 2005). The data of the compilation is available in the Supplementary Table 2 and in Mantovanelli (2013). The details of the model age from the cores 7616 and 7620, based on 14 C dating, are available in de Mahiques et al 2011.…”

“…We avoid the use of strong acids in the Sm-Nd isotope system since the use of HCl (1N) (Revel et al, 1996) induces significant REE removal (Clauer et al, 1993), and dramatically alters 147 Sm / 144 Nd and 143 Nd / 144 Nd ratios (Innocent et al, 2000). Different procedures of acid attacks, detailed in Mantovanelli (2013), were tested to determine the optimal leaching sequence for our sediments. Thus, the samples passed through a partial extraction to remove bioclasts.…”

“…Sul, e a quarta do mundo (Piola et al, 2005) em área de drenagem, com extensão de 3.200.000 km 2 , descarregando cerca de 23.000 m 3 s -1 de água e 57.000.000 m 3 ano -1 de sedimento no oceano Atlântico Sul (Mantovanelli, 2013). Se estende por 5 países, No verão, a ação dos ventos de nordeste causa uma retração da pluma do Rio de la Plata para o sul e costa afora.…”
