5 Formation

5.1 Formation

Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.

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

All about Anthracite and Quartzite Properties

Know all about Anthracite and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Anthracite and Quartzite belong to Metamorphic Rocks.Texture of Anthracite is Amorphous, Glassy whereas that of Quartzite is Foliated, Granular. Anthracite appears Veined or Pebbled and Quartzite appears Lustrous. The luster of Anthracite is shiny while that of Quartzite is vitreous. Anthracite 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 Anthracite 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.
