Definition
Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

All about Laterite and Quartzite Properties
Know all about Laterite and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Laterite belongs to Sedimentary Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Laterite is Earthy, Massive, Porphyritic whereas that of Quartzite is Foliated, Granular. Laterite appears Rough and Banded and Quartzite appears Lustrous. The luster of Laterite is dull while that of Quartzite is vitreous. Laterite is available in brown, buff, red colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses of Laterite are an oil and gas reservoir, source of bauxite, 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.
