Syenite and Quartzite


Definition

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

Formation

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

All about Quartzite and Syenite Properties

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