Banded iron formations are predominantly Precambrian in age most are 1.8 to 2.2 billion years. Sedimentary rock - Sedimentary rock - Iron-rich sedimentary rocks Almost all sedimentary rocks are iron-bearing in the sense that mudrocks, sandstones, and carbonates typically have an iron content of several percent. Nevertheless, sedimentary rocks ...

Banded iron-formations BIFs occur in the Precambrian geologic record over a wide time span. Beginning at 3.8 Ga Isua, West Greenland, they are part of Archean cratons and range in age from about 3.5 until 2.5 Ga. Their overall volume reaches a maximum at about 2.5 Ga iron-formations in the Hamersley Basin of Western Australia and they disappear from the geologic record at about 1.8 Ga ...
The Au concentrations in pyrrhotite and pyrite reach 6 and 0.3 ppm, respectively, in the Kalahari Goldridge banded-iron-formation-hosted gold deposit, and Au in pyrrhotite may sometimes exist as NPs, whereas As concentrations in pyrrhotite and pyrite are both low and lie
Feb 27, 2015 Obviously, banded iron formations contain iron technically, iron oxide, or rust. If you follow mining, you also know that the banded iron formations are one of the most important sources of iron in the modern world two of the largest producers, Australia and China, have enormous reserves of iron stored within their banded iron formations.
banded iron formation BIF is a sedimentary rock characterized by alternating bands of iron oxide and chert. Individual bands may vary in thickness from less than a millimetre to metres, and the overall succession of bands may be hundreds of metres thick. The principal iron minerals are the iron oxides hematite and magnetite.1 BIFs have a chemical

Banded iron formation BIF consists of finely interstratified chemical sediments rich in iron oxides, carbonates, andor silicates that are precursor deposits to the worlds largest iron ore bodies see Chapter 13.13. The second class of deposits, granular iron formations GIF, comprises iron oxide- and silicate-rich granular material deposited in high-energy environments on broad continental shelves.
1st Floor. A nearly 3-billion-year-old banded iron formation from Canada shows that the atmosphere and ocean once had no oxygen. Photosynthetic organisms were making oxygen, but it reacted with the iron dissolved in seawater to form iron oxide minerals on the ocean floor, creating banded iron formations. The dark layers in this boulder are mainly composed of magnetite Fe3O4 while the red layers are
Banded Iron formations occur in Proterozoic rocks, ranging in age from1.8 to 2.5 billion years old. They are composed of alternating layers ofiron-rich material commonly magnetite and silica chert. Each layer isrelatively thin, varying in thickness from a millimeter or so up to severalcentimeters. Here is one theory as to how they might have formed

Apr 10, 2013 Banded iron formations are of economic interest as they host the worlds largest iron ore deposits and many gold deposits. 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
