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'.
Shonkinite is a rare, dark-coloured and intrusive igneous rock which contains augite and orthoclase feldspar as its primary constituents

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.
Shonkinites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

Serpentinite vs Shonkinite 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 Shonkinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Shonkinite. Learn more about Serpentinite vs Shonkinite in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Shonkinite include Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Serpentinite and Shonkinite, 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 Shonkinite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Serpentinite and Shonkinite
Here you can know more about Serpentinite and Shonkinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Shonkinite consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Shonkinite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Shonkinite, the texture, color and appearance plays an important role in determining the type of rock. Serpentinite is available in black, brown, colourless, green, grey, white colors whereas, Shonkinite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Serpentinite is Rough and Dull and that of Shonkinite is Banded and Foilated. Properties of rock is another aspect for Serpentinite vs Shonkinite. The hardness of Serpentinite is 3-5 and that of Shonkinite is 5.5-6. The types of Serpentinite are Jadeitite whereas types of Shonkinite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Serpentinite and Shonkinite is white, greenish white or grey. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Shonkinite is 0.92 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 Shonkinite is heat resistant, impact resistant, wear resistant.
