Definition
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone
  
Websterite is ultramafic and ultrabasic rock that consists of roughly equal proportions of orthopyroxene and clinopyroxene. It is a special type of pyroxenite.

Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
  
Websterite can be formed as cumulates in ultramafic intrusions by accumulation of pyroxene crystals at the base of the lava chamber.

All about Quartzite and Websterite Properties
Know all about Quartzite and Websterite properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Websterite belongs to Igneous Rocks.Texture of Quartzite is Foliated, Granular whereas that of Websterite is Clastic, Granular, Phaneritic, Porphyritic. Quartzite appears Lustrous and Websterite appears Layered, Banded, Veined and Shiny. The luster of Quartzite is vitreous while that of Websterite is dull to vitreous to submetallic. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Websterite is available in black to grey, bluish - grey, dark greenish - grey, green, light greenish grey 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 Websterite are cemetery markers, commemorative tablets, creating artwork, laboratory bench tops, jewelry, sea defence, tombstones.
