“…Where dated, the offshore volcanic activity of the NW-SE trending Paraíba, Pernambuco and Bahia seamounts is 85-78 Ma (Cherkis et al, 1992), and are likely melts associated with the Martin Vaz-Trindade, Ascension and Saint Helena hot spot-plumes systems (Cherkis et al, 1992;O'Connor and le Roex, 1992;Ernesto, 2005). As the South American plate moved off the plume, thermal cooling and subsidence ensued.…”

“…A bacia oceânica tem cerca de 1000km de extensão em norte-sul e 1200km em leste-oeste. A borda norte é delimitada pela Cadeia de Ferraz (Cherkis, 1992) e, na borda sul, pela Cadeia Cruzeiro do Sul (Souza, 1991) e pela Elevação do Rio Grande (Oreiro et al, 2008;Mohriak et al, 2010 (Gladczenko et al 1997) Gomes et al, 2000e Mohriak, 2003 …”

“…Caso haja, ocorreriam a serpentinização das rochas ultramáfi cas do manto, hidrotermalismo de baixa temperatura e consequente geração de CH 4 e H 2 de origem abiogenética (e.g. Horita & Berndt, 1999;Holm & Chrlou, 2001;Colon et al, 2002;Charlou et al, 2002;Fruh-Green et al, 2003;Proskurowski, 2008), sendo importante sob ponto de vista de recursos energéticos de hidrocarbonetos. Para a conclusão, são desejados dados detalhados de magnetometria, gravimetria e prospecção sísmica, além de batimetria detalhada por multi-feixe.…”

“…In the western part of the Brazil basin, there is a group of the Bahia sea mounts, composed of several chains mainly of north western strike [1]. There is one reliable age determina tion (62 ± 4 Ma) made with use of isotopic 40 Ar/ 39 Ar of the basalt, composing the southern chain of these sea mounts [2].…”

“…In the center of the northern chain, the largest sea mounts Stocks and Gröll [1] are located; they are sit uated at a single base represented by a free lenselike elevation with a strike similar to the strike of the total chain (Fig. 1).…”
