Formation

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