International audience; The Araçuaí-Ribeira belt formed during the amalgamation of West Gondwana in the late Neoproterozoic. Its evolution included a main tectonometamorphic peak at 600–580 Ma and a minor peak associated with the final collision

International audience; The Ibituruna quartz-syenite was emplaced as a sill in the Ribeira-Aracuai Neoproterozoic belt (Southeastern Brazil) during the last stages of the Gondwana supercontinent amalgamation. We have measured the Anisotropy of Magnet
