Several stratigraphic units in the Hamersley Group contain banded iron formation (e.g., the Marra Mamba Fe-Fm. & the Brockman Fe-Fm.). The samples here are folded jaspilites with bands of yellowish-brown "tiger-eye" (asbestiform quartz having chatoyancy). The Hamersley Group is an upper Neoarchean to lower …

Banded iron formation -

Banded iron formation (BIF) is the principal source of iron. BIF is a rock type composed of alternating silica- and iron-rich bands. Banded iron formation is economically among the most important rock types as our society is heavily reliant on iron, which is mostly extracted from this rock.

The data suggest that the largest Paleoproterozoic banded iron formations may have formed not in a stable, quiescent sea, but instead as a result of increased influx of iron- and silica-rich solutions during periods of increased magmatism and submarine hydrothermal activity in a rift basin environment.

The banded iron formations of the Hamersley Province in the Pilbara region of Western Australia, are the thickest and most extensive rocks of this type in the world. It is estimated that after they were originally deposited, about 2470 to 2450 million years ago, they covered some 150 000 km2 and contained about 300 trillion tonnes of iron.
