Banded Iron formations occur in Proterozoic rocks, ranging in age from 1.8 to 2.5 billion years old. They are composed of alternating layers of iron-rich material commonly magnetite and silica chert.Banded iron formation BIF is a lithological term applied to a thinly bedded or laminated chemical sedimentary rock consisting of successive layers of fine-grained quartz, iron oxides, carbonates, andor silicates, typically containing 2040 of iron and 4050 of silica Trendall 2002 Klein 2005.Much research has been conducted on these banded iron formations BIF over the last 15-20 years. This contribution seeks to provide an overview of old and new facts and critical discussion on the latest ideas regarding the origin of these sediments in the early Proterozoic. The recently suggested stratified ocean water model and a new stratified lake water model are compared using new ...Aug 11, 2013 Banded iron formations BIFs are different they were all formed at a time where the earth was a decidedly different environment than it is today. Banded iron formations are critical to our current economy as they are by far the biggest source of economic iron deposits. BIF from the USA Image CC. A BIF is hard and heavy sedimentary stone.

They become less common after 1,800 mya. The total amount of oxygen locked up in the banded iron beds is estimated to be perhaps twenty times the volume of oxygen present in the modern atmosphere of Earth.Banded iron beds are an important commercial source of iron ore, such as the Pilbara regionThe earliest evidence of this process dates back to the Banded Iron Formations, which reach a peak occurrence in metamorphosed sedimentary rock at least 3.5 billion years old. Most of the major economic deposits of iron ore are from Banded Iron formations. These formations, were created as sediments in ancient oceans and are found in rocks in ...Nov 01, 2019 Banded iron formation BIF deposition was the likely result of oxidation of ferrous iron in seawater by either oxygenic photosynthesis or iron-dependent anoxygenic photosynthesisphotoferrotrophy. BIF deposition, however, remains enigmatic because the photosynthetic biomass produced during iron oxidation is conspicuously absent from BIFs. We have

The stage was set for the formation of banded iron on the seafloor. Heres how it happened as cyanobacteria proliferated, they produced more and more oxygen, which reacted with greater and greater amounts of free iron. The resulting iron oxide sank to the seafloor, forming a continuous layer.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.Jan 06, 2021 This rusted iron is in the different layers of banded iron formation BIF created about 3.7 billion years ago. The alternating layers in banded iron formations represent rock being oxidized. This is when early photosynthetic life was just trying to get started by releasing free oxygen into Earths early atmosphere. Table of Contents show.
