During the Cenozoic Era / Paleogene Period (65 - 23 Ma), subduction of the Pacific Nazca Plate beneath the continental part of the South American Plate gave rise to the Andean belt.

In southeast Brazil, an important tectonic event probably related to the alkaline magmatism at the end of the Mesozoic initiated the formation of the Continental Rift of Southeast Brazil and the adjacent mountain chains Serra do Mar and Mantiqueira.
