Definition
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay
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
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
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.

Claystone 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. Claystone vs Metapelite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Claystone and Properties of Metapelite. Learn more about Claystone vs Metapelite in the next section. The interior uses of Claystone include Decorative aggregates, Entryways, Floor tiles, Homes and Interior decoration whereas the interior uses of Metapelite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Claystone and Metapelite, they have various applications in construction industry. The uses of Claystone in construction industry include As a sintering agent in steel industry to process iron ore, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Metapelite include Cement manufacture, Construction aggregate, For road aggregate.
More about Claystone and Metapelite
Here you can know more about Claystone and Metapelite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Metapelite consists of mineral content and compound content. The mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Metapelite includes Albite, Chlorite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Claystone vs Metapelite, the texture, color and appearance plays an important role in determining the type of rock. Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors. Appearance of Claystone is Rough and Dull and that of Metapelite is Banded. Properties of rock is another aspect for Claystone vs Metapelite. The hardness of Claystone is 3.5-4 and that of Metapelite is 5-6. The types of Claystone 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 Claystone is white while that of Metapelite is unknown. The specific heat capacity of Claystone is 0.92 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.Claystone is heat resistant, impact resistant whereas Metapelite is heat resistant, impact resistant, pressure resistant.
