Definition

Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture

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

Formation

When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.

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

All about Tonalite and Quartzite Properties

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