Archaeological Significance
Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

All about Jadeitite and Quartzite Properties
Know all about Jadeitite and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Jadeitite and Quartzite belong to Metamorphic Rocks.Texture of Jadeitite is Earthy whereas that of Quartzite is Foliated, Granular. Jadeitite appears Rough and Dull and Quartzite appears Lustrous. The luster of Jadeitite is waxy and dull while that of Quartzite is vitreous. Jadeitite is available in black, brown, green, grey, white colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses of Jadeitite are commemorative tablets, creating artwork, jewelry 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.
