Eclogite vs Boninite


Definition

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

Formation

Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.  
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

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

More about Boninite and Eclogite

Here you can know more about Boninite and Eclogite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Boninite and Eclogite consists of mineral content and compound content. The mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite 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 Igneous Rocks. When we have to compare Boninite vs Eclogite, the texture, color and appearance plays an important role in determining the type of rock. Boninite is available in bluish - grey, brown, green, grey colors whereas, Eclogite is available in black, brown, green, grey, pink, white colors. Appearance of Boninite is Dull and Soft and that of Eclogite is Dull, Banded and Foilated. Properties of rock is another aspect for Boninite vs Eclogite. The hardness of Boninite is 7 and that of Eclogite is 3.5-4. The types of Boninite are Basalt whereas types of Eclogite are Eclogite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Boninite and Eclogite is white. The specific heat capacity of Boninite is 0.84 kJ/Kg K and that of Eclogite is 0.75 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Boninite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Eclogite is heat resistant.
