Formation

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.

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

All about Latite and Quartzite Properties

Know all about Latite and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Latite belongs to Igneous Rocks while Quartzite belongs to Metamorphic Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Quartzite is Foliated, Granular. Latite appears Rough and Quartzite appears Lustrous. The luster of Latite is subvitreous to dull while that of Quartzite is vitreous. Latite 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 Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, 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.
