    Banded iron formations are almost exclusively Precambrian in age, with most deposits dating to the late Archean (2500-2800 Ma) with a secondary peak of deposition in the Orosirian period of the Paleoproterozoic (1850 Ma). Minor amounts were deposited in the early Archean and in the Neoproterozoic (750 Ma). The youngest known banded iron formation is an early Cambrian formation
