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'.
Pegmatite rock is a holocrystalline, intrusive igneous rock which is composed of interlocking phaneritic crystals

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.
Pegmatite rock is holocrystalline, intrusive igneous rock which is formed by partial melting and dewatering during the process of metamorphism.

Serpentinite vs Pegmatite 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 Pegmatite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Pegmatite. Learn more about Serpentinite vs Pegmatite in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Pegmatite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Serpentinite and Pegmatite, 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 Pegmatite include As dimension stone, Building houses or walls, Construction aggregate, For road aggregate, Landscaping.
More about Serpentinite and Pegmatite
Here you can know more about Serpentinite and Pegmatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Pegmatite consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Pegmatite includes Apatite, Beryl, Feldspar, Fluorite, Garnet, Lepidolite, Quartz, Silica, Spodumene, Topaz. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Pegmatite, 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, Pegmatite is available in black, brown, cream, green, grey, pink, red, rust, silver, white, yellow colors. Appearance of Serpentinite is Rough and Dull and that of Pegmatite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Serpentinite vs Pegmatite. The hardness of Serpentinite is 3-5 and that of Pegmatite is 7. The types of Serpentinite are Jadeitite whereas types of Pegmatite are Granite Pegmatite, Gabbro Pegmatite and Diorite Pegmatite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Serpentinite and Pegmatite is white, greenish white or grey. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Pegmatite is 0.79 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 Pegmatite is heat resistant, impact resistant, pressure resistant.
