Eclogite vs Shonkinite

Definition

Definition

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

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.
Shonkinites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

Eclogite vs Shonkinite 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 Shonkinite Reserves. Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature. Shonkinite is a rare, dark-coloured and intrusive igneous rock which contains augite and orthoclase feldspar as its primary constituents. 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 Shonkinite information and Eclogite vs Shonkinite characteristics in the upcoming sections.

You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Shonkinite, 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, Shonkinite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Shonkinite is Banded and Foilated. Properties of rock is another aspect for Eclogite vs Shonkinite. The hardness of Eclogite is 3.5-4 and that of Shonkinite is 5.5-6. The types of Eclogite are Eclogite whereas types of Shonkinite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Eclogite and Shonkinite is white. The specific heat capacity of Eclogite is 0.75 kJ/Kg K and that of Shonkinite is 0.92 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 Shonkinite is heat resistant, impact resistant, wear resistant.
