5.1 Formation

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

Shonkinites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

All about Quartzite and Shonkinite Properties

Know all about Quartzite and Shonkinite properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Shonkinite belongs to Igneous Rocks.Texture of Quartzite is Foliated, Granular whereas that of Shonkinite is Earthy. Quartzite appears Lustrous and Shonkinite appears Banded and Foilated. The luster of Quartzite is vitreous while that of Shonkinite is subvitreous to dull. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Shonkinite is available in brown, buff, cream, green, grey, pink, 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 Shonkinite are cemetery markers, creating artwork.
