Definition
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature
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'.

Formation
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.
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.

Eclogite vs Serpentinite 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. Eclogite vs Serpentinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Eclogite and Properties of Serpentinite. Learn more about Eclogite vs Serpentinite in the next section. The interior uses of Eclogite include Decorative aggregates and Interior decoration whereas the interior uses of Serpentinite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Eclogite and Serpentinite, they have various applications in construction industry. The uses of Eclogite in construction industry include and that of Serpentinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.
More about Eclogite and Serpentinite
Here you can know more about Eclogite and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Serpentinite consists of mineral content and compound content. The mineral content of Eclogite includes Amphibole, Coesite, Corundum, Dolomite, Garnet, Kyanite, Lawsonite, Paragonite, Phengite, Pyroxene, Quartz, Rutile, Zoisite and mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Serpentinite, the texture, color and appearance plays an important role in determining the type of rock. Eclogite is available in black, brown, green, grey, pink, white colors whereas, Serpentinite is available in black, brown, green, grey, white colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Eclogite vs Serpentinite. The hardness of Eclogite is 3.5-4 and that of Serpentinite is 3-5. The types of Eclogite are Eclogite whereas types of Serpentinite are Jadeitite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Eclogite is white while that of Serpentinite is white, greenish white or grey. The specific heat capacity of Eclogite is 0.75 kJ/Kg K and that of Serpentinite is 0.95 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Eclogite is heat resistant whereas Serpentinite is heat resistant.
