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

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

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