Definition
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone
Novaculite is a dense, hard, fine-grained, siliceous metamorpic rock which is a type of chert that breaks with conchoidal fracture

Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
Novaculite forms when microcrystals of silicon dioxide grow within soft sediments that become limestone or chalk. The formation of Novaculite can be either of chemical or biological origin.

All about Quartzite and Novaculite Properties
Know all about Quartzite and Novaculite properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Novaculite belongs to Sedimentary Rocks.Texture of Quartzite is Foliated, Granular whereas that of Novaculite is Banded, Glassy, Rough, Vitreous. Quartzite appears Lustrous and Novaculite appears Glassy or Pearly. The luster of Quartzite is vitreous while that of Novaculite is waxy and dull. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Novaculite is available in black, brown, green, grey, red, 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 Novaculite are cemetery markers, gemstone, in aquifers, in fire-starting tools, jewelry, manufacture of tools, pebbles are used in ball mills to grind in ceramics industry, to determine the gold content of jewelry.
