3.65–2.10Ga history of crust formation from zircon geochronology and isotope geochemistry of the Quijingue and Euclides plutons, Serrinha nucleus, Brazil

The Serrinha nucleus is one of the Archaean granite-gneiss terrains of São Francisco craton, Brazil. In this area, many granitic rocks formed during the Trans-Amazonian orogeny, and intruded during and following a greenschist metamorphic event. Zircon geochronology and Nd isotopes record a history of extensive crustal reworking that began at 3.6Ga and culminated in the emplacement and deformation of a continental arc during the Trans-Amazonian …
