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

All about Coal and Pegmatite Properties

Know all about Coal and Pegmatite properties here. All properties of rocks are important as they define the type of rock and its application. Coal belongs to Sedimentary Rocks while Pegmatite belongs to Igneous Rocks.Texture of Coal is Amorphous, Glassy whereas that of Pegmatite is Pegmatitic. Coal appears Veined or Pebbled and Pegmatite appears Layered, Banded, Veined and Shiny. The luster of Coal is dull to vitreous to submetallic while that of Pegmatite is grainy, pearly and vitreous. Coal is available in black, brown, dark brown, grey, light to dark grey colors whereas Pegmatite is available in black, brown, cream, green, grey, pink, red, rust, silver, white, yellow colors. The commercial uses of Coal are alumina refineries, electricity generation, liquid fuel, manufacture of soap, solvents, dyes, plastics and fibres, paper industry and that of Pegmatite are creating artwork, jewelry, source of corundum, tourmalines, beryls and topaz.
