Definition
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone
A ganister is a hard, fine-grained quartzose sandstone or orthoquartzite which is basically used in the manufacture of silica brick typically used to line furnaces and is a type of sedimentary rocks.

Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
Ganisters are formed by the destruction of easily weathered minerals mainly feldspar, within the surface horizon of soil by soil-forming processes.

All about Quartzite and Ganister Properties
Know all about Quartzite and Ganister properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Ganister belongs to Sedimentary Rocks.Texture of Quartzite is Foliated, Granular whereas that of Ganister is Clastic, Granular, Rough. Quartzite appears Lustrous and Ganister appears Rough. The luster of Quartzite is vitreous while that of Ganister is dull. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Ganister is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. The commercial uses of Quartzite and Ganister 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.
