“…Many granitic plutons of Brasiliano age are associated with deep megashear zones (Fig. 1b) (e.g., Galindo et al, 1991;Neves and Vauchez, 1995;Ferreira et al, 1998;Campos et al, 2000). The Rio Espinharas pluton crops out in low-strain zones between two oblique NNE strike -slip megafaults (Figs.…”

“…Em função dessa diversidade, várias classificações de cunho petrográ-fico, geoquímico e geocronológico foram propostas para a região (Almeida et al 1967;Sial 1984;Ferreira et al 1998;Santos e Medeiros 1999;Brito-Neves et al 2000;Ferreira et al 2004;Guimarães et al 2004). Embora não exista uma classificação consensual, os dados geocronológicos existentes levaram Ferreira et al (2004) a definir três eventos principais de magmatismo nesse domínio.…”

“…(iv) Complex Neoproterozoic granites: The Borborema Province is characterized by important granite plutonism related to the Brasiliano Orogeny (Ferreira et al, 1995). Most of the early-collision granites present U-Pb zircon crystallization ages in the 630-620 Ma interval.…”
