Definition
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone
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

Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
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 vs Metapelite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Quartzite vs Metapelite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Quartzite and Properties of Metapelite. Learn more about Quartzite vs Metapelite in the next section. The interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Metapelite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Quartzite and Metapelite, they have various applications in construction industry. The uses of Quartzite in construction industry include Arrowheads, As dimension stone, Cement manufacture, Construction aggregate, Cutting tool, For road aggregate, Making natural cement, Production of glass and ceramics, Rail track ballast, Roadstone and that of Metapelite include Cement manufacture, Construction aggregate, For road aggregate.
More about Quartzite and Metapelite
Here you can know more about Quartzite and Metapelite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Quartzite and Metapelite consists of mineral content and compound content. The mineral content of Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz and mineral content of Metapelite includes Albite, Chlorite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Quartzite vs Metapelite, the texture, color and appearance plays an important role in determining the type of rock. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas, Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors. Appearance of Quartzite is Lustrous and that of Metapelite is Banded. Properties of rock is another aspect for Quartzite vs Metapelite. The hardness of Quartzite is 6-7 and that of Metapelite is 5-6. The types of Quartzite are Not Available whereas types of Metapelite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Quartzite is white while that of Metapelite is unknown. The specific heat capacity of Quartzite is 0.75 kJ/Kg K and that of Metapelite is 0.72 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Metapelite is heat resistant, impact resistant, pressure resistant.
