This work deals with the Neoarchean magmatic and metamorphic evolution of the extreme south of the São Francisco Craton (CSF) in the Serra da Babilônia region (Bom Sucesso - MG) and is presented in the form of two scientific articles. The first article presents the petrographic and lithochemical characteristics of the rocks found around the Serra da Babilônia, seeking to discuss their geological evolution in relation to the Rio das Velhas Orogeny. The second article discusses U-Th-Pb chemical dating by electron microprobe carried out on monazite crystals with phosphate-silicate reaction crowns found in a metacharnoenderite of the Babilônia unit and the relationship between the age found and the presence of the crowns in the crystals.
