Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
Jasperoid is a rare and peculiar type of metasomatic alteration of rocks. It is formed by extreme alteration of wall rocks within a shear zone which may occur in sediments, andesites, trachytes and basalts.

All about Quartzite and Jasperoid Properties
Know all about Quartzite and Jasperoid properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Jasperoid belongs to Sedimentary Rocks.Texture of Quartzite is Foliated, Granular whereas that of Jasperoid is Earthy. Quartzite appears Lustrous and Jasperoid appears Glassy or Pearly. The luster of Quartzite is vitreous while that of Jasperoid is vitreous and pearly. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Jasperoid is available in black, brown, colourless, 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 Jasperoid are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
