Definition
Metapelite is an old and currently not widely used field geological term for a clay rich fine-grained clastic sediment or sedimentary rock, i.e. mud or a mudstone
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

All about Metapelite and Quartzite Properties
Know all about Metapelite and Quartzite properties here. All properties of rocks are important as they define the type of rock and its application. Metapelite and Quartzite belong to Metamorphic Rocks.Texture of Metapelite is Foliated whereas that of Quartzite is Foliated, Granular. Metapelite appears Banded and Quartzite appears Lustrous. The luster of Metapelite is earthy while that of Quartzite is vitreous. Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors whereas Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. The commercial uses of Metapelite are commemorative tablets, creating artwork 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.
