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.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

All about Coal and Enderbite Properties
Know all about Coal and Enderbite properties here. All properties of rocks are important as they define the type of rock and its application. Coal belongs to Sedimentary Rocks while Enderbite belongs to Igneous Rocks.Texture of Coal is Amorphous, Glassy whereas that of Enderbite is Granular. Coal appears Veined or Pebbled and Enderbite appears Veined or Pebbled. The luster of Coal is dull to vitreous to submetallic while that of Enderbite is not available. Coal is available in black, brown, dark brown, grey, light to dark grey colors whereas Enderbite is available in black, grey, orange, pink, white 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 Enderbite are curling, gemstone, laboratory bench tops, tombstones.
