Kimberlite vs Eclogite


Definition

Definition
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature   
Kimberlite is a rare, blue-tinged, coarse-grained intrusive igneous rock, which sometimes contains diamonds and is mostly found in South Africa and Siberia.

Formation

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.   
Kimberlite is an igneous rock and is the main source of diamonds. Its formation takes place deep beneath the Earth’s surface between 150 to 450 kilometres, and are erupted rapidly and violently.

Eclogite vs Kimberlite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Eclogite and Kimberlite Reserves. Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature. Kimberlite is a rare, blue-tinged, coarse-grained intrusive igneous rock, which sometimes contains diamonds and is mostly found in South Africa and Siberia.. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Eclogite vs Kimberlite information and Eclogite vs Kimberlite characteristics in the upcoming sections.

More about Eclogite and Kimberlite

Here you can know more about Eclogite and Kimberlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Kimberlite 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 Kimberlite includes Garnet, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Kimberlite, the texture, color and appearance plays an important role in determining the type of rock. Eclogite is available in black, brown, colourless, green, grey, pink, white colors whereas, Kimberlite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Kimberlite is Dull and Banded. Properties of rock is another aspect for Eclogite vs Kimberlite. The hardness of Eclogite is 3.5-4 and that of Kimberlite is 6-7. The types of Eclogite are Not Available whereas types of Kimberlite are Basaltic Kimberlites and Micaceous Kimberlites. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Eclogite and Kimberlite is white. The specific heat capacity of Eclogite is Not Available and that of Kimberlite 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.Eclogite is heat resistant whereas Kimberlite is heat resistant, impact resistant.
