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