1.1 Definition

Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Kenyte is a variety of porphyritic phonolite or trachyte rock with rhomb shaped phenocrysts of anorthoclase with variable olivine and augite in a glassy matrix

5 Formation

5.1 Formation

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

Kenyte is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Quartzite and Kenyte Properties

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