Most of the world's important iron ore resources occur in banded iron formations, which are almost exclusively of Precambrian age (i.e. greater than 541 million years old). BIFs occur on all continents. Iron was the first metal to be discovered in Australia by explorer Edward John Eyre in the Middleback Ranges in South Australia. Banded-iron formation | rock | Britannica Banded-iron formation (BIF), chemically precipitated sediment, typically thin bedded or laminated, consisting of 15 percent or more iron of sedimentary origin and layers of chert, chalcedony, jasper, or quartz. Such formations occur on all the continents and usually are older than 1.7 billion years. They also are highly metamorphosed. Banded Iron Formation "BIF" | Geology Page Algoma-type banded iron formations were deposited as chemical sediments along with other sedimentary rocks (such as greywacke and shale) and volcanics in and adjacent to volcanic arcs and spreading centers. Iron and silica were derived from hydrothermal sources associated with volcanic centres. Algoma-type iron formations are common in Archean green-stone belts, but may also occur in …

Banded iron formation-hosted gold deposits have the potential to become large-tonnage mines with extended mining lives. Due to the appeal of these deposits, gold exploration companies are targeting

Aug 14, 2017 · Banded iron formation consists of layers of iron oxides (typically either magnetite or hematite) separated by layers of chert (silica-rich sedimentary rock). Each layer is usually narrow (millimeters to few centimeters). The rock has a distinctively banded appearance because of differently colored lighter silica – and darker iron-rich layers.
