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

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