Formation
Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.

All about Quartzite and Gabbro Properties
Know all about Quartzite and Gabbro properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Gabbro belongs to Igneous Rocks.Texture of Quartzite is Foliated, Granular whereas that of Gabbro is Phaneritic. Quartzite appears Lustrous and Gabbro appears Veined and Shiny. The luster of Quartzite is vitreous while that of Gabbro is not available. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Gabbro is available in dark grey to black 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 Gabbro are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones.
