Magmatism, rifting and sedimentation related to Late Paleoproterozoic mantle plume events of Central and Southeastern Brazil

Domal uplift, a giant tholeiitic mafic dyke swarm, anorogenic bimodal volcanism and plutonism and extensive intracontinental rift sedimentary sequences are recorded at the Late Paleoproterozoic of the Central and Southeastern Brazil. Mantle plume events at 1.77 Ga and around 1.72 Ga are thought as an unifying concept for these geological features.
