Origin and age of coeval gabbros and leucogranites in the northern subprovince of the borborema province, NE Brazil
The Paleoproterozoic Serrinha – Pedro Velho Complex comprises orthogneisses and migmatites, exposed in the south part of the Archean São José do Campestre Massif, Rio Grande do Norte domain of the Borborema Province, NE, Brazil. During the Ediacaran, the Serrinha - Pedro Velho Complex underwent metamorphism at HT/LP conditions in a tectonic setting dominated by dextral transpressive deformation, dated at ∼575Ma. Crustal melting generated various plutons and dykes of leucogranites with...[Show more]
