Most Banded Iron Formations are dated from 3.8Ga (early Archaean) - 1.8Ga (late Paleoproterozoic). That's plenty of time on Earth, and thus most are of a highly deformed variety (discussed below). There is a widespread connection of deformed BIF's to the major greenstone belts of the world, thus establishing a likely mafic origin of their parent rocks.
