About this document
Neoproterozoic Magmatic Arcs in Brazil by Oliver Dnalien is a document available to read on EtoBox.
This review synthesizes the evolution of two distinct Neoproterozoic magmatic arc systems in the Ribeira belt of southeastern Brazil, highlighting their accretion onto the São Francisco paleocontinent. The Inner Magmatic Arc System, formed between 650 and 595 Ma, includes several arcs and indicates early subduction processes, while the Outer Magmatic Arc System reflects a two-stage evolution from an intra-oceanic to a continental setting. The findings contribute to understanding the dynamic tectonic history
