Formation

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.

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

All about Pyrolite and Quartzite Properties

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