Banded iron formation

This page is currently not sponsored. Click here to sponsor this page.
Commonly termed BIFs by geologists, they are iron-rich rocks almost always of Precambrian age, predominantly associated with the great oxygenation event (GOE) about 2.3-2.8 billion years ago. It typically consists of repeated, thin iron oxide layers (a few mm to a few cm in thickness) but may be banded from a microscopic to a metre scale. The oxide bands are dark grey to to black magnetite (Fe3O4) or hematite (Fe2O3), alternating with bands of iron-poor shales and cherts, usually red in color, of similar thickness, or iron rich silicates and carbonates, including siderite, ankerite, riebeckite, stilpnomelane, minnesotaite, etc. They provide our major source of iron ore, usually after upgrading by various hypogene and supergene processes.
