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
Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism

Archaeological Significance
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.
Greenschist is medium grade metamorphic rock, formed by the metamorphosis of mudstone or shale, or some types of igneous rock, when it is subjected to higher temperatures and pressures.

More about Metapelite and Greenschist
Here you can know more about Metapelite and Greenschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Metapelite and Greenschist consists of mineral content and compound content. The mineral content of Metapelite includes Albite, Chlorite, Quartz and mineral content of Greenschist includes Alusite, Amphibole, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Serpentine, Sillimanite, Staurolite, Talc. You can also check out the list of all Metamorphic Rocks. When we have to compare Metapelite vs Greenschist, the texture, color and appearance plays an important role in determining the type of rock. Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors whereas, Greenschist is available in dark greenish - grey, green colors. Appearance of Metapelite is Banded and that of Greenschist is Layered and Shiny. Properties of rock is another aspect for Metapelite vs Greenschist. The hardness of Metapelite is 5-6 and that of Greenschist is 3.5-4. The types of Metapelite are Metamorphic rock whereas types of Greenschist are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Metapelite is while that of Greenschist is white. The specific heat capacity of Metapelite is 0.72 kJ/Kg K and that of Greenschist is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Metapelite is heat resistant, impact resistant, pressure resistant whereas Greenschist is impact resistant, pressure resistant, water resistant.
