Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
Blue Granite is an igneous rock which is a variety of Larvikite and is known mainly for the presence of thumbnail-sized crystals of feldspar.

All about Quartzite and Blue Granite Properties
Know all about Quartzite and Blue Granite properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Blue Granite belongs to Igneous Rocks.Texture of Quartzite is Foliated, Granular whereas that of Blue Granite is Phaneritic. Quartzite appears Lustrous and Blue Granite appears Shiny. The luster of Quartzite is vitreous while that of Blue Granite is subvitreous to dull. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Blue Granite 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 Blue Granite are cemetery markers, commemorative tablets, creating artwork, curling.
