Eclogite vs Boninite


Boninite vs Eclogite


Definition

Definition
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature   
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

Eclogite vs Boninite 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 Boninite Reserves. Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature. Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction. 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 Boninite information and Eclogite vs Boninite characteristics in the upcoming sections.

The uses of Eclogite in construction industry include Not yet used and that of Boninite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.

More about Eclogite and Boninite

Here you can know more about Eclogite and Boninite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Boninite 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 Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Boninite, 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, Boninite is available in bluish - grey, brown, colourless, green, grey colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Boninite is Dull and Soft. Properties of rock is another aspect for Eclogite vs Boninite. The hardness of Eclogite is 3.5-4 and that of Boninite is 7. The types of Eclogite are Not Available whereas types of Boninite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Eclogite and Boninite is white. The specific heat capacity of Eclogite is Not Available and that of Boninite 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 Boninite is heat resistant, impact resistant, pressure resistant, wear resistant.
