Eclogite vs Phyllite


Phyllite vs Eclogite


Definition

Definition
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature   
Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks

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.   
Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.

Eclogite vs Phyllite 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 Phyllite Reserves. Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature. Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks. 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 Phyllite information and Eclogite vs Phyllite characteristics in the upcoming sections.

More about Eclogite and Phyllite

Here you can know more about Eclogite and Phyllite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Phyllite 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 Phyllite includes Albite, Alusite, Amphibole, Apatite, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc, Zircon. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Phyllite, 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, Phyllite is available in black to grey, light greenish grey colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Phyllite is Crinkled or Wavy. Properties of rock is another aspect for Eclogite vs Phyllite. The hardness of Eclogite is 3.5-4 and that of Phyllite is 1-2. The types of Eclogite are Not Available whereas types of Phyllite 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 Phyllite is white. The specific heat capacity of Eclogite is Not Available and that of Phyllite 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 Phyllite is heat resistant, pressure resistant, water resistant.
