Formation

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

Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

All about Quartzite and Evaporite Properties

Know all about Quartzite and Evaporite properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Evaporite belongs to Sedimentary Rocks.Texture of Quartzite is Foliated, Granular whereas that of Evaporite is Earthy. Quartzite appears Lustrous and Evaporite appears Glassy, Vesicular and Foilated. The luster of Quartzite is vitreous while that of Evaporite is subvitreous to dull. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Evaporite is available in green, grey, silver, white 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 Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite.
