Formation

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.

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

All about Jasperoid and Quartzite Properties

Know all about Jasperoid and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Jasperoid belongs to Sedimentary Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Jasperoid is Earthy whereas that of Quartzite is Foliated, Granular. Jasperoid appears Glassy or Pearly and Quartzite appears Lustrous. The luster of Jasperoid is vitreous and pearly while that of Quartzite is vitreous. Jasperoid is available in black, brown, green, grey, pink, white colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses 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) 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.
