5 Formation

5.1 Formation

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.

Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
