Definition
Whiteschist is an uncommon rock type belonging to a class of metamorphic rock, this is formed at high-ultra-high pressures
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds

Formation
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.
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.

All about Whiteschist and Coal Properties
Know all about Whiteschist and Coal properties here. All properties of rocks are important as they define the type of rock and its application. Whiteschist belongs to Metamorphic Rocks while Coal belongs to Sedimentary Rocks.Texture of Whiteschist is Foliated whereas that of Coal is Amorphous, Glassy. Whiteschist appears Banded and Foilated and Coal appears Veined or Pebbled. The luster of Whiteschist is subvitreous to dull while that of Coal is dull to vitreous to submetallic. Whiteschist is available in colourless, green, grey, white colors whereas Coal is available in black, brown, dark brown, grey, light to dark grey colors. The commercial uses of Whiteschist are creating artwork, gemstone, jewelry, production of lime and that of Coal are alumina refineries, electricity generation, liquid fuel, manufacture of soap, solvents, dyes, plastics and fibres, paper industry.
