Eclogite vs Adakite


Adakite vs Eclogite


Definition

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

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.   
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.

Eclogite vs Adakite 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 Adakite Reserves. Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature. 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. 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 Adakite information and Eclogite vs Adakite characteristics in the upcoming sections.

Due to some exceptional properties of Eclogite and Adakite, they have various applications in construction industry. The uses of Eclogite in construction industry include Not yet used and that of Adakite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.

More about Eclogite and Adakite

Here you can know more about Eclogite and Adakite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Adakite 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 Adakite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Adakite, 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, Adakite is available in black, brown, light to dark grey colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Adakite is Dull and Soft. Properties of rock is another aspect for Eclogite vs Adakite. The hardness of Eclogite is 3.5-4 and that of Adakite is 3-4. The types of Eclogite are Not Available whereas types of Adakite are Not Available. 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 Adakite is bluish black. The specific heat capacity of Eclogite is Not Available and that of Adakite is Not Available. 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 Adakite is heat resistant, pressure resistant, wear resistant.
