Definition

Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass

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

Formation

Shoshonite 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 forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

Shoshonite 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 Shoshonite and Eclogite Reserves. Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass. 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.

More about Shoshonite and Eclogite

Here you can know more about Shoshonite and Eclogite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shoshonite and Eclogite consists of mineral content and compound content. The mineral content of Shoshonite includes Pyroxene 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 Igneous Rocks. When we have to compare Shoshonite vs Eclogite, the texture, color and appearance plays an important role in determining the type of rock. Shoshonite is available in brown- black, dark brown colors whereas, Eclogite is available in black, brown, green, grey, pink, white colors. Appearance of Shoshonite is Dull and that of Eclogite is Dull, Banded and Foilated. Properties of rock is another aspect for Shoshonite vs Eclogite. The hardness of Shoshonite is 6 and that of Eclogite is 3.5-4. The types of Shoshonite are Intermediate volcanic rock 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 Shoshonite is white to grey while that of Eclogite is white. The specific heat capacity of Shoshonite 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.Shoshonite is heat resistant, pressure resistant whereas Eclogite is heat resistant.
