Formation

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

Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

All about Quartzite and Laterite Properties

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