Formation

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

Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

All about Quartzite and Latite Properties

Know all about Quartzite and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Latite belongs to Igneous Rocks.Texture of Quartzite is Foliated, Granular whereas that of Latite is Aphanitic to Porphyritic. Quartzite appears Lustrous and Latite appears Rough. The luster of Quartzite is vitreous while that of Latite is subvitreous to dull. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Latite is available in black, brown, 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 Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo).
