How Does Iron Formation Form. Photosynthetic organisms were making oxygen, but it reacted with the iron. Nearly all of earth's major iron ore deposits are in rocks that formed over 1.8 billion years ago.

The deposition basin must contain waters that are ferruginous (rich in iron ). This implies they are also anoxic, since ferrous iron oxidizes to ferric iron within hours or days in the presence. Web how does iron ore form? Photosynthetic organisms were making oxygen, but it reacted with the iron. At that time earth's oceans contained abundant dissolved iron and almost no dissolved. Nearly all of earth's major iron ore deposits are in rocks that formed over 1.8 billion years ago. Web banded iron formations (bifs) the distinctive banding in bifs is thought to result from cyclic variations in the availability of oxygen and iron in ancient seawater. Web the first three forms are observed at ordinary pressures.
