Eclogite vs Teschenite

Definition

Definition

Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature
Teschenite is coarse- to fine-grained, dark-coloured intrusive igneous rock that usually occurs in sills, dikes and irregular masses and is always altered to some extent

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.
Teschenite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Eclogite vs Teschenite 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 Teschenite Reserves. Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature. Teschenite is coarse- to fine-grained, dark-coloured intrusive igneous rock that usually occurs in sills, dikes and irregular masses and is always altered to some extent. 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 Teschenite information and Eclogite vs Teschenite characteristics in the upcoming sections.

Eclogite vs Teschenite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others.

You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Teschenite, 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, Teschenite is available in dark grey to black colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Teschenite is Veined and Shiny. Properties of rock is another aspect for Eclogite vs Teschenite. The hardness of Eclogite is 3.5-4 and that of Teschenite is 7. The types of Eclogite are Eclogite whereas types of Teschenite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Eclogite is white while that of Teschenite is black. The specific heat capacity of Eclogite is 0.75 kJ/Kg K and that of Teschenite is 0.79 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 Teschenite is impact resistant, pressure resistant, wear resistant.
