Definition
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.
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

Features
Host Rock for Lead
Easily splits into thin plates, It is One of the Oldest, Strongest and Hardest Rock
Archaeological Significance
Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Serpentinite 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. Serpentinite vs Metapelite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Metapelite. Learn more about Serpentinite vs Metapelite in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Metapelite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Serpentinite and Metapelite, they have various applications in construction industry. The uses of Serpentinite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement and that of Metapelite include Cement manufacture, Construction aggregate, For road aggregate.
More about Serpentinite and Metapelite
Here you can know more about Serpentinite and Metapelite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Metapelite consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides 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 Serpentinite vs Metapelite, the texture, color and appearance plays an important role in determining the type of rock. Serpentinite is available in black, brown, green, grey, white colors whereas, Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors. Appearance of Serpentinite is Rough and Dull and that of Metapelite is Banded. Properties of rock is another aspect for Serpentinite vs Metapelite. The hardness of Serpentinite is 3-5 and that of Metapelite is 5-6. The types of Serpentinite are Jadeitite 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 Serpentinite is white, greenish white or grey while that of Metapelite is . The specific heat capacity of Serpentinite is 0.95 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.Serpentinite is heat resistant whereas Metapelite is heat resistant, impact resistant, pressure resistant.
