Resumo: The Passira Anorthositic Complex (PAC) is situated in Pernambuco State, Northeastern Brazil, within the Rio Capibaribe Terrain of the Borborema Province. Host rocks are rhiacian migmatitic gneisses. The PAC is a massif-type complex of batholithic proportions composed mainly of metamorphosed anorthosite, gabbro, norite, diorite and ultramafic lenses mineralized in Fe-Ti oxide minerals. A dyke swarm formed by apatite-rich ferro-diorite enriched in Zr, Ba and LREE, occurs around the complex. A multicrystal U-Pb zircon age of 1.70+0.02 Ga was obtained for the anorthosite, which is interpreted as|the age of crystallization. The associated granites (now orthogneisses) include metaluminous alkaline; sub-alkaline garnet-bearing and peraluminous types having anorogenic geochemical characteristics. They have U-Pb ages between 1.58±0.09 Ga and 1.68±0.09 Ga, obtained in zircon and monazite monocrystals by laser ablation mass spectrometry. The PAC and associated granites behaved as a tectonic unit during the Brasiliano-age deformations. The association was formed in Rio Capibaribe Terrain during an extensional event occurred at the Statherian-Callymian transition
