The spark to put together this volume on banded iron formation (BIF)related highgrade iron ore was born in 2005 during a steamy night in Carajás where the iron research group from the Universidade Federal Minas Gerais, Vale geologists, Carlos Rosière and Steffen Hagemann, were hotly debating the hypogene alteration genesis for the highgrade, jaspilitehosted Serra Norte iron ore deposits.

Jul 26, 2017· At billion years old and weighing in at tonnes, the banded iron formation is so heavy that Museum engineers had to reinforce the floor underneath it in Hintze Hall. 'The rock tells a fascinating story,' says Prof Richard Herrington, Head of Earth Sciences at the Museum .

Banded Iron Formations (BIFs) Plusnet
Banded Iron Formations (BIFs) The banded iron formations were laid down in the early days, when the planet was almost devoid of oxygen. They were deposited on the bed of shallow seas. The upper picture of an outcrop of Banded Iron Formation comes from 'Earth Story' by Lamb Sington (BBC Books).
Types of Sedimentary Rock ThoughtCo
The banded iron formation was laid down more than billion years ago during the Archean Eon. It consists of black iron minerals and redbrown chert. During the Archean, Earth still had its original atmosphere of nitrogen and carbon dioxide.
Geochemistry of Muro Banded IronFormation, Central Nigeria
Muro Banded IronFormation occurs in the Proterozoic Toto Schist Belt, central Nigeria. It consists preponderantly of oxide facies and minor carbonate facies. The oxide facies is made up of alternating bands of quartz (metachert) with those of hematite + magnetite + martite ± .

Nov 29, 2000· Abstract. The discovery of biogenic magnetite at depths of ∼ km in the subsurface ( 16) has been used as a marker of activity of DIRB in the deep subsurface. In addition, the presence of magnetite in association with isotopically light carbon in carbonate minerals in the Precambrian banded iron formations (BIFs),...
A Mesoproterozoic iron formation | PNAS
Apr 24, 2018· Iron formations (IFs) are common before 1,800 million years ago (Ma) and again at ∼750 Ma, but are remarkably absent for the billion years in between. We report on a 1,400Ma IF of ∼520 gigatons Fe from the Xiamaling Formation on the North China Craton. Biomarker analyses suggest that anoxygenic phototrophic bacteria were involved in Fe(II) oxidation, and further geochemical analysis .

Tiger Iron Beads. Banded iron formations are a distinctive type of rock often found in sedimentary rocks that are billions of years old. These formations consist of thin layers of iron oxides, such as hematite, alternating with bands of jasper. Each layer of material is relatively thin, varying in thickness from a millimeter or so up to several centimeters.
