Banded iron formation (BIF) deposits

Sedimentary and chemical deposited iron formations (BIF), from which almost all iron is obtained, are one of the great iron sources in the world, and in Greenland. Here, deposits related to banded iron formations (BIF), mostly so-called Algoma type, are typical for Archaean greenstone belts formed in continental rifts or at continental margins.
