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.
  
Pegmatite rock is holocrystalline, intrusive igneous rock which is formed by partial melting and dewatering during the process of metamorphism.

All about Aplite and Pegmatite Properties
Know all about Aplite and Pegmatite properties here. All properties of rocks are important as they define the type of rock and its application. Aplite and Pegmatite belong to Igneous Rocks.Texture of Aplite is Granular, Graphic whereas that of Pegmatite is Pegmatitic. Aplite appears Veined or Pebbled and Pegmatite appears Layered, Banded, Veined and Shiny. The luster of Aplite is dull to pearly to subvitreous while that of Pegmatite is grainy, pearly and vitreous. Aplite is available in black, grey, orange, pink, white colors whereas Pegmatite is available in black, brown, cream, green, grey, pink, red, rust, silver, white, yellow colors. The commercial uses of Aplite are curling, gemstone, laboratory bench tops, small sculptures, tombstones and that of Pegmatite are creating artwork, jewelry, source of corundum, tourmalines, beryls and topaz.
