“…The possibilities of correlations with the coeval terranes of the Islas Malvinas (Falkland Islands: Cingolani and Varela, 1976;Thomas et al, 1998;Wareham et al, 1998;Jacobs et al, 1999), the Mesoproterozoic belt of Uruguay (Preciozzi et al, 1999), as well as the Sunsas belt of the South American Amazon Craton (Sadowski and Bettencourt, 1996;Sato and Tassinari, 1997) or the Brazilian coastal and southern regions (Sato, 1998) have not yet been clarified.…”

“…Vale da Promissão), a bacia subside e acomoda espessa seção de sedimentos marinhos rasos (tempestitos), passando distalmente a marinho profundo na região de Santo Corazón (turbiditos), marcando provavelmente a região onde o rift intercepta a margem continental e se abre em uma bacia oceânica em expansão. O final do Mesoproterozóico (~ 1,0 Ga), é marcado pela colisão do sul da Amazônia com a Laurentia (Sadowski & Bettencourt, 1996), resultando na amalgamação final do Supercontinente de Rodínia. Esta colisão se reflete no interior do antepaís, deformando, metamorfizando e afetando por intenso hidrotermalismo os depósitos da Zona Central do Aulacógeno Aguapeí.…”

“…Moreover, the field reconnaissance carried out during the present study has identified other granite bodies with textural features similar to the Pedra do Gavião syenogranite, suggesting the possible presence of an A-type granitic suite in the area that has not been properly studied. Mesoproterozoic within-plate A-type granites, chronologically correlated to the K´Mudku period, have been recognized primarily in the southwestern margin of the Amazon craton and related to the Grenvillian-Sunsas orogenic belts (Priem et al 1971, Sadowski & Bettencourt 1996, Dall'Agnol et al 1999, Bettencourt et al 1999, Geraldes et al 2004, Cordani et al 2010, Teixeira et al 2010. The A-type Pedra do Gavião syenogranite has a post-collisional to within-plate geochemical signature, U-Pb crystallization age of 1218 Ma, inheritance ages between 1810 and 1780 Ma, which, together with the Sm-Nd isotopic data suggests partial melting of basement rocks of the Paleoproterozoic Cauaburi Complex.…”
