Quartzite and Syenite


Definition

Definition
Syenite is a coarse-grained igneous rock which is composed mainly of alkali feldspar and various ferromagnesian minerals   
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Formation

Formation
Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.   
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

All about Syenite and Quartzite Properties

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