Migmatite vs Eclogite

Definition

Definition

Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature

Formation

Formation

Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

Migmatite 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 Migmatite and Eclogite Reserves. Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components. 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 Migmatite vs Eclogite information and Migmatite vs Eclogite characteristics in the upcoming sections.

Migmatite vs Eclogite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Migmatite vs Eclogite characteristics assist us to distinguish and recognize rocks.

More about Migmatite and Eclogite

Here you can know more about Migmatite and Eclogite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Migmatite and Eclogite consists of mineral content and compound content. The mineral content of Migmatite includes Biotite, Chlorite, Feldspar, Garnet, Graphite, Hornblade, Micas, Muscovite or Illite, Quartz, Quartzite, Silica, Zircon 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 Metamorphic Rocks. When we have to compare Migmatite vs Eclogite, the texture, color and appearance plays an important role in determining the type of rock. Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black colors whereas, Eclogite is available in black, brown, green, grey, pink, white colors. Appearance of Migmatite is Dull, Banded and Foilated and that of Eclogite is Dull, Banded and Foilated. Properties of rock is another aspect for Migmatite vs Eclogite. The hardness of Migmatite is 5.5-6.5 and that of Eclogite is 3.5-4. The types of Migmatite are Diatexites and Metatexites 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 Migmatite and Eclogite is white. The specific heat capacity of Migmatite is 0.79 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.Migmatite is heat resistant, pressure resistant whereas Eclogite is heat resistant.
