Hardcap alteration in banded iron formation Sulfur as an indicator The Precambrian banded iron formations (BIF) of the Hamersley Iron Ore Province Pilbara Craton Western Australia underwent an extensive period of secondary weathering with the development of a weathered altered ferricrete zone.Banded iron formations (also known as banded ironstone formations or BIFs) are distinctive units of sedimentary rock that are almost always of Precambrian age A typical BIF consists of repeated thin layers (a few millimeters to a few centimeters in thickness) of silver to black iron oxides either magnetite (Fe3O4) or hematite (Fe2O3) alternating with bands of iron poor shales and cherts.

Banded iron formations (BIFs) have been at the center of many debates in geology especially regarding the early (i e Archean and Paleoproterozoic) Earth and its surface environments BIFs are chemical sedimentary rocks that have an anomalously high iron content ( 15 wt Fe) and typically contain layers of chert (Klein 2005).The formations are abundant around the time of the Great Oxygenation Event 2 400 mya They become less common after 1 800 mya The total amount of oxygen locked up in the banded iron beds is estimated to be perhaps twenty times the volume of oxygen present in the modern atmosphere of Earth Banded iron beds are an important commercial source of iron ore such as the Pilbara region.
