Called banded iron formations or BIFs, these ancient rocks formed between 3.8 and 1.7 billion years ago. The stripes represent alternating layers of silica-rich quartz and iron-rich minerals like hematite and magnetite. In India, iron-formations were designated as “Banded Hematite Quartzite” and “Banded Magnetite Quartzite”. Stratigraphic

Banded iron formation Wikipedia

Banded iron formations (also known as banded ironstone formations or BIFs) are distinctive units of sedimentary rock consisting of alternating layers of iron oxides and iron-poor chert. Almost all of these formations are of Precambrian age and are thought to record the oxygenation of the Earth's oceans.. A typical banded iron formation consists of repeated, thin layers (a few

Otjihase, Ongombo, Ongeama). The magnetite quartz-ite in this area appears as either a well banded iron for-mation (e.g. Otjihase) or as a quartzite carrying variable amounts of disseminated magnetite (e.g. Matchless). The magnetite quartzites in the vicinity of the Match-less Amphibolite Belt generally occur in the form of
