Formation of Banded iron formation

Banded iron formation Formation

Banded iron formation formation took place millions of years ago. There are a variety of Banded iron formation Uses and the Banded iron formation Reserves are found in many countries around the world. The rocks in the earth’s crust continuously undergo changes in their composition which leads to formation of other rocks. Each rock has a unique formation process. Formation of Banded iron formation is explained below:

• The banded iron layers are formed in sea water when oxygen is released by photosynthetic cyano-bacteria. The oxygen then combines with dissolved iron in ocean to form insoluble iron oxides, which precipitated out, forming a thin layer of banded iron formation on ocean floor.
