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.
Pyrolite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Coal and Pyrolite Properties

Know all about Coal and Pyrolite properties here. All properties of rocks are important as they define the type of rock and its application. Coal belongs to Sedimentary Rocks while Pyrolite belongs to Igneous Rocks.Texture of Coal is Amorphous, Glassy whereas that of Pyrolite is Phaneritic. Coal appears Veined or Pebbled and Pyrolite appears Rough and Shiny. The luster of Coal is dull to vitreous to submetallic while that of Pyrolite is shiny. Coal is available in black, brown, dark brown, grey, light to dark grey colors whereas Pyrolite is available in dark greenish - 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 Pyrolite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds.
