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'.
Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs

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.
Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.

Serpentinite vs Adakite 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 Adakite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Adakite. Learn more about Serpentinite vs Adakite in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Adakite include Decorative aggregates, Floor tiles, Homes, Hotels and Kitchens. Due to some exceptional properties of Serpentinite and Adakite, 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 Adakite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.
More about Serpentinite and Adakite
Here you can know more about Serpentinite and Adakite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Adakite consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Adakite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Adakite, 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, Adakite is available in black, brown, light to dark grey colors. Appearance of Serpentinite is Rough and Dull and that of Adakite is Dull and Soft. Properties of rock is another aspect for Serpentinite vs Adakite. The hardness of Serpentinite is 3-5 and that of Adakite is 3-4. The types of Serpentinite are Jadeitite whereas types of Adakite are Intermediate volcanic 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 Adakite is bluish black. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Adakite 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.Serpentinite is heat resistant whereas Adakite is heat resistant, pressure resistant, wear resistant.
