1 Definition
1.1 Definition
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

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.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

All about Coal and Quartzite Properties

Know all about Coal and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Coal belongs to Sedimentary Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Coal is Amorphous, Glassy whereas that of Quartzite is Foliated, Granular. Coal appears Veined or Pebbled and Quartzite appears Lustrous. The luster of Coal is dull to vitreous to submetallic while that of Quartzite is vitreous. Coal is available in black, brown, dark brown, grey, light to dark grey colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow 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 Quartzite are an oil and gas reservoir, as armour rock for sea walls, cemetery markers, commemorative tablets, in aquifers, laboratory bench tops, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, used in aquariums.
