1.1 Definition

Minette is a variety of Lamprophyre and is porphyritic alkaline igneous rock which is mainly dominated by biotite and potassic feldspar

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

5.1 Formation

Minette formation takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.

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

All about Minette and Quartzite Properties

Know all about Minette and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Minette belongs to Igneous Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Minette is Porphyritic whereas that of Quartzite is Foliated, Granular. Minette appears Dull, Banded and Foilated and Quartzite appears Lustrous. The luster of Minette is subvitreous to dull while that of Quartzite is vitreous. Minette is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses of Minette are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo) 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.
