Definition

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

Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite

Formation

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

Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.

All about Quartzite and Oolite Properties

Know all about Quartzite and Oolite properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Oolite belongs to Sedimentary Rocks.Texture of Quartzite is Foliated, Granular whereas that of Oolite is Clastic or Non-Clastic. Quartzite appears Lustrous and Oolite appears Rounded and Rough. The luster of Quartzite is vitreous while that of Oolite is pearly to shiny. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Oolite is available in black, blue, brown, cream, green, grey, pink, red, 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 Oolite are creating artwork, jewelry, used in aquariums.
