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.   
Coal forms from the accumulation of plant debris in a swamp environment which is buried by sediments such as mud or sand and then compacted to form coal.

All about Aplite and Coal Properties

Know all about Aplite and Coal properties here. All properties of rocks are important as they define the type of rock and its application. Aplite belongs to Igneous Rocks while Coal belongs to Sedimentary Rocks.Texture of Aplite is Granular, Graphic whereas that of Coal is Amorphous, Glassy. Aplite appears Veined or Pebbled and Coal appears Veined or Pebbled. The luster of Aplite is dull to pearly to subvitreous while that of Coal is dull to vitreous to submetallic. Aplite is available in black, grey, orange, pink, white colors whereas Coal is available in black, brown, dark brown, grey, light to dark grey colors. The commercial uses of Aplite are curling, gemstone, laboratory bench tops, small sculptures, tombstones and that of Coal are alumina refineries, electricity generation, liquid fuel, manufacture of soap, solvents, dyes, plastics and fibres, paper industry.
