Formation
Formation
Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

All about Aplite and Quartzite Properties
Know all about Aplite and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Aplite belongs to Igneous Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Aplite is Granular, Graphic whereas that of Quartzite is Foliated, Granular. Aplite appears Veined or Pebbled and Quartzite appears Lustrous. The luster of Aplite is dull to pearly to subvitreous while that of Quartzite is vitreous. Aplite is available in black, grey, orange, pink, white colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses of Aplite are curling, gemstone, laboratory bench tops, small sculptures, tombstones 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.
