Banded Iron Formation Goa India

geology and genesis of the major banded iron formation,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..archean banded iron formations of india,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.archean banded iron formations of india,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 formation rock,banded iron formation are distinctive units of sedimentary rock that are almost always of precambrian age. banded iron formation is available in red, reddish brown colors. the streak of a rock is the color of powder produced when it is dragged across an unweathered surface. the streak of banded iron formation is white..banded iron formation,banded iron formations are almost exclusively precambrian in age, with most deposits dating to the late archean (2500-2800 ma) with a secondary peak of deposition in the orosirian period of the paleoproterozoic (1850 ma). minor amounts were deposited in the early archean and in the neoproterozoic (750 ma). the youngest known banded iron formation is an early cambrian formation.banded iron formation,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..precambrian banded iron formations of india,precambrian banded iron formations of india proceedings of the group discussion held at dharwad, may 20-22nd, 1985 the annual generaj me~ting of the geological society of india, this year, was held at dharwad, the seat of the karnatak university..banded iron formations (figure 1). formed rapidly,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.
