AbstractAbstract
[en] Geochronological data obtained in plutonic rocks of the Sao Vicente/Caico Groups present U/Pb values around 2.15 Ga. These rocks may have involved from an initial mantle or lower crust melting and fractionation process by 2.62-2.65 Ga., that is evidenced from Sm/Nd model ages. Relation betwen TTG-sequence and tectonic setting of the area and other localities in NE-Brazil suggest that the Transamazonic orogeny was the main crust-forming episode of the Borborema Province.
