Quartzite and Tonalite

1 Definition
1.1 Definition
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone
Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture

5 Formation
5.1 Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.

All about Quartzite and Tonalite Properties

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