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.

Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

More about Eclogite and Granulite

Here you can know more about Eclogite and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Granulite 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 Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Granulite, the texture, color and appearance plays an important role in determining the type of rock. Eclogite is available in black, brown, green, grey, pink, white colors whereas, Granulite is available in black, brown colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Eclogite vs Granulite. The hardness of Eclogite is 3.5-4 and that of Granulite is 6-7. The types of Eclogite are Eclogite whereas types of Granulite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Eclogite and Granulite is white. The specific heat capacity of Eclogite is 0.75 kJ/Kg K and that of Granulite is 0.14 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 Granulite is heat resistant, wear resistant.
