Layered intrusions and volcanic sequences in Central Brazil: Geological and geochronological constraints for Mesoproterozoic (1.25Â Ga) and Neoproterozoic (0.79Â Ga) igneous associations

Equivalent Mesoproterozoic (ca. 1.25 Ga) and Neoproterozoic (ca. 0.79 Ga) extensional events have been reported in other continents (e.g., North America). These igneous associations described within an allochtonous block in the Brasília Belt provide additional constraints, therefore, for continental reconstruction models before the break-up of Rodinia.
