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.

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

All about Banded iron formation and Quartzite Properties

Know all about Banded iron formation and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Banded iron formation belongs to Sedimentary Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Banded iron formation is Banded, Trellis whereas that of Quartzite is Foliated, Granular. Banded iron formation appears Layered, Banded, Veined and Shiny and Quartzite appears Lustrous. The luster of Banded iron formation is earthy while that of Quartzite is vitreous. Banded iron formation is available in red, reddish brown colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses of Banded iron formation are as a touchstone, cemetery markers, creating artwork and that of Quartzite are an oil and gas reservoir, as armour rock for sea walls, cemetery markers, commemorative tablets, in aquifers, laboratory bench tops, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, used in aquariums.
