Coal and Quartzite


Definition

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

Formation

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

Know all about Quartzite and Coal properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Coal belongs to Sedimentary Rocks.Texture of Quartzite is Foliated, Granular whereas that of Coal is Amorphous, Glassy. Quartzite appears Lustrous and Coal appears Veined or Pebbled. The luster of Quartzite is vitreous while that of Coal is dull to vitreous to submetallic. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Coal is available in black, brown, dark brown, grey, light to dark grey colors. The commercial uses 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 and that of Coal are alumina refineries, electricity generation, liquid fuel, manufacture of soap, solvents, dyes, plastics and fibres, paper industry.
