Banded iron formation - Wikipedia

Banded iron formations are almost exclusively Precambrian in age, with most deposits dating to the late Archean (2800-2500 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 in western China.

It is characterized by the occurrence of the oldest Cu-Zn volcanogenic massive sulfide (VMS) deposits in China. Recent geochronological data indicates that the QGB also hosts a certain amount of Neoarchean BIF-type iron deposits. Hence,a detailed study on the enigmatic association of VMS and BIF deposits should be conducted urgently.
