Formation
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.
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

Know all about Coal and Granulite properties here. All properties of rocks are important as they define the type of rock and its application. Coal belongs to Sedimentary Rocks while Granulite belongs to Metamorphic Rocks.Texture of Coal is Amorphous, Glassy whereas that of Granulite is Granoblastic. Coal appears Veined or Pebbled and Granulite appears Veined or Pebbled. The luster of Coal is dull to vitreous to submetallic while that of Granulite is vitreous. Coal and Granulite are available in black, brown, dark brown, grey, light to dark grey 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 Granulite are curling, gemstone, laboratory bench tops, soil conditioner, tombstones.
