Variações da estrutura da crosta, litosfera e manto para a plataforma Sul Americana através de funções do receptor para ondas P e S

Abstract: RESUMO.Utilizamos neste trabalho duas metodologias distintas, a função do receptor com ondas P e a função do receptor com ondas S, para mapear variações da crosta e interfaces do manto (litosfera-astenosfera, 410 km e 660 km) em diferentes estações sismográficas na placa Sul-Americana. No estudo da interface litosferaastenosfera, por ser o primeiro realizado nesta região, utilizamos as estações temporárias do IAG/USP em conjunto com as estações permanentes da rede mundial cobrindo toda a placa Sul-Americana.

“…We compiled crustal thickness estimates from all recently published receiver function studies including stations in South America, especially those from the Brazilian Lithosphere Seismic Project (BLSP) in Brazil (Bianchi, 2008;Julià et al, 2008;Lloyd et al, 2010). Crustal thickness estimates from other stations in central and northern Brazil were also compiled from Krüger et al (2002), Rosa et al (2012), Albuquerque et al (2011) and unpublished monographs such as Pedreschi (1989) and Costa (2005).…”

“…The 2AG1MT well reached the Cuiabá Group, considered to be basement at this site, at a depth of 1943 m. The 2JA1GO and 2TQ1MT wells have maximum depths of 2107 m and 2020 m, respectively; both bottomed in the Devonian sequence of the Paraná Basin and did not reach basement. (4) Crustal thickness estimates based on receiver-function data(Assumpção et al, 2002;Bianchi, 2008;Lloyd et al, 2010; Albuquerque et al, 2010;Figures 1 to 3)and deep seismic-refraction data(Soares et al, 2006;Ventura et al, 2011; Figures 1 and 2) were compiled byPavão et al (2012).…”
