Definition

Epidosite is a highly altered epidote and quartz bearing rock which is a type of metasomatite, essentially altered basalt

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

Formation

Epidosite 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.

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.

Epidosite vs Shoshonite 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 Epidosite and Shoshonite Reserves. Epidosite is a highly altered epidote and quartz bearing rock which is a type of metasomatite, essentially altered basalt. 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. 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 Epidosite vs Shoshonite information and Epidosite vs Shoshonite characteristics in the upcoming sections.

More about Epidosite and Shoshonite

Here you can know more about Epidosite and Shoshonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Epidosite and Shoshonite consists of mineral content and compound content. The mineral content of Epidosite includes Olivine, Plagioclase, Pyroxene and mineral content of Shoshonite includes Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Epidosite vs Shoshonite, the texture, color and appearance plays an important role in determining the type of rock. Epidosite is available in black, brown, light to dark grey colors whereas, Shoshonite is available in brown- black, dark brown colors. Appearance of Epidosite is Dull and Soft and that of Shoshonite is Dull. Properties of rock is another aspect for Epidosite vs Shoshonite. Hardness of Epidosite and Shoshonite is 6. The types of Epidosite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite whereas types of Shoshonite are Intermediate volcanic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Epidosite and Shoshonite is white to grey. The specific heat capacity of Epidosite is 0.84 kJ/Kg K and that of Shoshonite 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.Epidosite is heat resistant, pressure resistant, wear resistant whereas Shoshonite is heat resistant, pressure resistant.
