Definition
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

All about Quartzite and Conglomerate Properties
Know all about Quartzite and Conglomerate properties here. All properties of rocks are important as they define the type of rock and its application. Quartzite belongs to Metamorphic Rocks while Conglomerate belongs to Sedimentary Rocks.Texture of Quartzite is Foliated, Granular whereas that of Conglomerate is Clastic. Quartzite appears Lustrous and Conglomerate appears Shiny and Rounded. The luster of Quartzite is vitreous while that of Conglomerate is dull. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. The commercial uses of Quartzite and Conglomerate 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.
