5 Formation

5.1 Formation

Gritstone is a type of sedimentary rock which was formed on the floors of wide river deltas where the grit deposits were laid down, with every tide or flood dumping another layer of sediment.

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

All about Gritstone and Quartzite Properties

Know all about Gritstone and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Gritstone belongs to Sedimentary Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Gritstone is Earthy whereas that of Quartzite is Foliated, Granular. Gritstone appears Layered and Foliated and Quartzite appears Lustrous. The luster of Gritstone is dull while that of Quartzite is vitreous. Gritstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses of Gritstone are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo), tombstones 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.
