Definition
A carbonate rock which is matrix supported and contains over 10% allochems in a carbonate mud matrix.
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

Archaeological Significance
Formation
Wackestone is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles settle down and are then compacted due to high temperature and pressure hence forming Wackestone.
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.

Wackestone 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. Wackestone vs Metapelite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Wackestone and Properties of Metapelite. Learn more about Wackestone vs Metapelite in the next section. The interior uses of Wackestone include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Metapelite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Wackestone and Metapelite, they have various applications in construction industry. The uses of Wackestone in construction industry include 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 Wackestone and Metapelite
Here you can know more about Wackestone and Metapelite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wackestone and Metapelite consists of mineral content and compound content. The mineral content of Wackestone 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 Wackestone vs Metapelite, the texture, color and appearance plays an important role in determining the type of rock. Wackestone 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 Wackestone is Rough and Dull and that of Metapelite is Banded. Properties of rock is another aspect for Wackestone vs Metapelite. The hardness of Wackestone is 2-3 and that of Metapelite is 5-6. The types of Wackestone are Marl, Shale and Argillite whereas types of Metapelite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wackestone is white while that of Metapelite is . The specific heat capacity of Wackestone is 0.39 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.Wackestone is heat resistant, impact resistant whereas Metapelite is heat resistant, impact resistant, pressure resistant.
