“…with T DM Nd of 860-1,200 Ma, 87 Sr/ 86 Sr i < 0.7035, zircon εHf (t) from þ14 to þ10, and T DM Hf of 840-1,010 Ma (Peixoto et al, 2017;Heilbron et al, 2020;Santiago et al, 2020). The Rio Negro Complex comprises intermediate to felsic plutonic rocks (620-790 Ma) with εNd (t) from þ5 to −3 and 87 Sr/ 86 Sr < 0.705, as well as high K calc-alkaline to shoshonitic felsic rocks (605-620 Ma) with εNd (t) = −3 to −14 and 87 Sr/ 86 Sr = 0.7050-0.7100 (Tupinambá et al, 2012).…”

“…A maior parte do arcabouço geológico da BHRI é composto por rochas cristalinas, principalmente rochas metamórficas (gnaisses) e ígneas intrusivas (granitoides) (Figura 3), mas também ocorrem, de forma mais restrita, milonitos, mármores, granulitos e charnoquitos (VIEIRA et al. , SANTIAGO et al 2020. As coberturas sedimentares são compostas pelos sedimentos semiconsolidados da Formação Barreiras (WEST & MELO 2020, SANTIAGO et al 2023 (GATTO et al 1983).…”

“…In this study we focus on mapping the FDS, PGDS, and SMDS that crop out in the continental area and the proximal margin tectono-magmatic features. These features are characterized by distinct structural trends and are evidence of pre-to syn-rift magmatic episodes that affected the margin (Almeida, 1986;Turner et al, 1994;Valente et al, 2009;Florisbal et al, 2014;Santiago et al, 2020;Almeida et al, 2013;Raposo, 2017;Guedes et al, 2005;Marques & Ernesto, 1998). The Ar-Ar ages of the FDS, PGDS and SDMDS indicate a main cristallisation period between 135-130 Ma, with possible recurrence during the rift, postrift, and drift tectonostratigraphic stages (Almeida et al, 1991).…”
