5 Formation

5.1 Formation

Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

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.
