Definition
Sandstone is defined as a rock which is composed of sand-sized grains of various minerals mostly of uniform size and often are smooth and rounded
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Formation
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

All about Sandstone and Quartzite Properties
Know all about Sandstone and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Sandstone belongs to Sedimentary Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Sandstone is Clastic, Granular, Rough whereas that of Quartzite is Foliated, Granular. Sandstone appears Rough and Quartzite appears Lustrous. The luster of Sandstone is dull while that of Quartzite is vitreous. Sandstone is available in beige, black, brown, 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 Sandstone are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, 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.
