Definition
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite
  
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

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

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