1.1 Definition
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds
Metapelite is an old and currently not widely used field geological term for a clay rich fine-grained clastic sediment or sedimentary rock, i.e. mud or a mudstone

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

All about Coal and Metapelite Properties

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