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

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

Serpentinite vs Eclogite 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 Eclogite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Eclogite. Learn more about Serpentinite vs Eclogite in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Eclogite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Serpentinite and Eclogite, 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 Eclogite include Not yet used.
More about Serpentinite and Eclogite
Here you can know more about Serpentinite and Eclogite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Eclogite consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Eclogite includes Amphibole, Coesite, Corundum, Dolomite, Garnet, Kyanite, Lawsonite, Paragonite, Phengite, Pyroxene, Quartz, Rutile, Zoisite. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Eclogite, 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, Eclogite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Serpentinite is Rough and Dull and that of Eclogite is Dull, Banded and Foilated. Properties of rock is another aspect for Serpentinite vs Eclogite. The hardness of Serpentinite is 3-5 and that of Eclogite is 3.5-4. The types of Serpentinite are Jadeitite whereas types of Eclogite 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 Eclogite is white, greenish white or grey. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Eclogite is Not Available. 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 Eclogite is heat resistant.
