Cauê Formation (Quadrilátero Ferrífero)

Name: Cauê Formation (Quadrilátero Ferrífero), isotope signatures
Creator: IsoFind

Minas Gerais, Brazil

Banded iron formationsFe

Type: Palaeoproterozoic banded iron formation (itabirite) and high-grade ores

Itabirites of the Cauê Formation, one of the world's major iron provinces. High-grade ores derive from hydrothermal alteration and deformation of the itabirites; the lightest in iron occur in the more deformed eastern domain.
