5 Formation

5.1 Formation

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

Pyrolite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Quartzite and Pyrolite Properties

Know all about Quartzite and Pyrolite properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Pyrolite belongs to Igneous Rocks.Texture of Quartzite is Foliated, Granular whereas that of Pyrolite is Phaneritic. Quartzite appears Lustrous and Pyrolite appears Rough and Shiny. The luster of Quartzite is vitreous while that of Pyrolite is shiny. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Pyrolite is available in dark greenish - grey 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 Pyrolite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds.
