Formation

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

Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

All about Quartzite and Turbidite Properties

Know all about Quartzite and Turbidite properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Turbidite belongs to Sedimentary Rocks.Texture of Quartzite is Foliated, Granular whereas that of Turbidite is Mud-rich, Sandy. Quartzite appears Lustrous and Turbidite appears Dull and Banded. The luster of Quartzite is vitreous while that of Turbidite is metallic. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Turbidite is available in black, brown, green, grey, pink 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 Turbidite are cemetery markers, creating artwork.
