Definition

Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate

Formation

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

Limestone is a sedimentary rock which is mainly made up of calcium carbonate.

All about Quartzite and Limestone Properties

Know all about Quartzite and Limestone properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Limestone belongs to Sedimentary Rocks.Texture of Quartzite is Foliated, Granular whereas that of Limestone is Clastic or Non-Clastic. Quartzite appears Lustrous and Limestone appears Rough and Banded. The luster of Quartzite is vitreous while that of Limestone is dull to pearly. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Limestone is available in beige, black, blue, brown, cream, gold, green, grey, light green, light grey, linen, pink, red, rust, silver, white, yellow colors. The commercial uses 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 and that of Limestone are animal feed filler, as a feed additive for livestock, paper industry, raw material for manufacture of quicklime, slaked lime, soil conditioner, used in aquariums, whiting material in toothpaste, paint and paper.
