Mineral deposit - Iron deposits | Britannica

Sedimentary iron deposits, from which almost all iron is obtained, can therefore be viewed as one of the world’s great mineral treasures. There are two major types of deposit. The first, and by far the most important, is banded iron formations (BIFs), so called because they are finely layered alternations of cherty silica and an iron mineral, generally hematite, magnetite, or siderite.

Banded iron formation - Wikipedia

Banded iron formations are distinctive units of sedimentary rock that are almost always of Precambrian age. A typical banded iron formation consists of repeated, thin layers of silver to black iron oxides, either magnetite or hematite, alternating with bands of iron-poor shales and cherts, often red in color, of similar thickness, and containing microbands of iron oxides. Some of the oldest known rock formations, are associated with banded iron …
