A-type granitoids (∼512 Ma) either intruded into Paleoproterozoic gneiss of the Alto Moxoto Terrane (Prata Complex and Serra da Engabelada Pluton) or into Early Neoproterozoic metavolcanic metasedimentary sequence of the Alto Pajeu Terrane (Serrote

The Neoproterozoic Brasiliano/Pan-African Orogeny in the Borborema Province (BP) NE Brazil, is characterized by intense granitic magmatism spatially associated with continental scale shear zones and metamorphism under high temperature conditions. U/P

The Caruaru-Arcoverde batholith, with an outcrop area of ~2000 km2, is one of the largest Brasiliano plutons in Borborema Province, northeastern Brazil. The batholith intrudes orthogneisses and supracrustal rocks characterized by flat-lying foliation

Intralithospheric differentiation and crustal growth: Evidence from the Borborema province, northeastern Brazil

Autor: Ignez P. Guimarães, Sérgio P. Neves, Silvana C. Melo, Gorki Mariano, Adejardo F. da Silva Filho

Publikováno v: Geology. 28:519-522

Thousands of cubic kilometers of high-K calc-alkalic magmas intruded the Borborema Province (northeastern Brazil) during the Neoproterozoic Brasiliano orogeny. They make up large batholiths in which mantle-derived mafic to intermediate rocks coexist
