Definition

Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass

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

Formation

Shoshonite 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.

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

All about Shoshonite and Quartzite Properties

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