- •
Late granitic magmatism along the coast of Brazil is proposed to be correlated.
- •
The coeval intrusion of basic and granitic magmas is followed by extensive magma mixing.
- •
A continental extension followed by a hotspot is proposed to be triggers.
- •
This magmatism follows orogenic collapse along the Araçuaí-Ribeira belt.
