Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
Larvikite 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 Larvikite Properties
Know all about Quartzite and Larvikite properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Larvikite belongs to Igneous Rocks.Texture of Quartzite is Foliated, Granular whereas that of Larvikite is Phaneritic. Quartzite appears Lustrous and Larvikite appears Shiny. The luster of Quartzite is vitreous while that of Larvikite is subvitreous to dull. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Larvikite is available in black, brown, light to dark grey, 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 Larvikite are cemetery markers, commemorative tablets, creating artwork.
