Archean banded iron formations (BIFs) are important lithologies for understanding the early Earth processes. Greenstone belts in the four Archean cratonic nucleii of peninsular India, namely, Singhbhum, Bastar, Dharwar, and Bundelkhand host BIF units that can be important candidates for case studies.
Banded iron formations (also known as banded ironstone formations or BIFs) are distinctive units of sedimentary rock that are almost always of Precambrian age.. A typical banded iron formation consists of repeated, thin layers (a few millimeters to a few centimeters in thickness) of silver to black iron oxides, either magnetite (Fe 3 O 4) or hematite (Fe 2 O 3), alternating with bands of iron ...
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.

Aug 14, 2015 Iron ore was mined from the banded iron formations of Goa, India, and transported through the Mandovi and Zuari estuaries for six decades until the ban on mining from September 2012. Here we focus on the environmental magnetic properties of sediments from the catchment area, upstream and downstream of these estuaries, and adjacent shelf during peak mining time.

Banded iron formations (or BIFs) are a distinctive type of rock often found in (Precambrian) sedimentary rocks.. They consist of repeated thin layers of iron oxides, either magnetite (Fe 3 O 4) or hematite (Fe 2 O 3), alternating with bands of iron-poor shale and chert.. Some of the oldest known rock formations, formed over 3,700 million years ago (mya), include banded iron layers.

With a current annual production of about 170 million tons (Mt), India is the sixth largest producer of high-grade iron ore (>60 wt % of Fe) in the world. The greater part of the high-grade iron ores of India (>5 billion tons reserve base) are hosted by voluminous banded iron formations of major Archean greenstone belt successions.

Department of Studies in Geology, Karnataka University, Dharwad-580003, Karnataka, INDIA Email: [email protected], [email protected] Abstract: Banded Iron Formations (BIF) is the economically prominent litho-units of the Sandur Schist Belt, hosting high-grade iron ore deposits.
Banded iron formation (BIF) is the principal source of iron. BIF is a rock type composed of alternating silica- and iron-rich bands. Banded iron formation is economically among the most important rock types as our society is heavily reliant on iron, which is mostly extracted from this rock.
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
occur in Southern Sector (Andhra Pradesh, Goa, Karnataka, Kerala Tamil Nadu). Karnataka alone contributes 72% of magnetite deposit in India. Of these, haematite is considered to be superior because of its higher grade. Indian deposits of haematite belong to the Precambrian Iron Ore Series and the ore is within banded iron ore formations

The iron ores of eastern India are part of the Iron Ore Group (IOG) that occurs within the Archean Singhbhum-North Orissa Craton (Jones, 1934). The Banded Iron Formation (BIF) is an important volcano-sedimentary rock formation of the Iron Ore Group (IOG) of Singhbhum and Orissa. The Precambrian IOG, ~3.1–3.3 Ga in age, contains metavolcanic and
3.1 Iron ores: World occurrences of BIF-hosted iron ores – a review Banded iron-formation hosted iron ore deposits account for the majority of current world production and contribute >31,000 Mt high-grade hematite resources of iron ore (Dalstra and Guedes, 2004).

Essay # 1. Banded Iron Formations of Precambrian Age (BIF): The BIF deposits are very well developed in India. Most of the Indian deposits are similar to those of the Lake Superior region of U.S.A., Brazil and Venezuela. Extensive outcrops of BIF are found in the states of Jharkhand, Orissa, Chhattisgarh, Maharashtra, Karnataka, Goa and Tamil Nadu.
banded iron-formation is depleted in these conshtuents. Zr, Hf, Rb, Sr, Ba, U, and Th distinguish the felsic clastic flux from mafic flux, which is characterized by an abundance of Cr, Ni, Co, Sc, V, and Y. Cherty banded iron-formation has depleted and less fractionated rare earth element (REE) patterns coupled with prominent positive Eu anomalies.
