Formation
Harzburgite 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 Harzburgite and Quartzite Properties
Know all about Harzburgite and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Harzburgite belongs to Igneous Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Harzburgite is Phaneritic whereas that of Quartzite is Foliated, Granular. Harzburgite appears Rough and Shiny and Quartzite appears Lustrous. The luster of Harzburgite is shiny while that of Quartzite is vitreous. Harzburgite 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 Harzburgite 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.
