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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

All about Coal and Jadeitite Properties
Know all about Coal and Jadeitite properties here. All properties of rocks are important as they define the type of rock and its application. Coal belongs to Sedimentary Rocks while Jadeitite belongs to Metamorphic Rocks.Texture of Coal is Amorphous, Glassy whereas that of Jadeitite is Earthy. Coal appears Veined or Pebbled and Jadeitite appears Rough and Dull. The luster of Coal is dull to vitreous to submetallic while that of Jadeitite is waxy and dull. Coal is available in black, brown, dark brown, grey, light to dark grey colors whereas Jadeitite is available in black, brown, colourless, green, grey, 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 Jadeitite are commemorative tablets, creating artwork, jewelry.
