Formation

Wehrlite 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 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.

Wehrlite vs Epidosite 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 Wehrlite and Epidosite Reserves. Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites. Epidosite is a highly altered epidote and quartz bearing rock which is a type of metasomatite, essentially altered basalt. 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 Wehrlite vs Epidosite information and Wehrlite vs Epidosite characteristics in the upcoming sections.

More about Wehrlite and Epidosite

Here you can know more about Wehrlite and Epidosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Epidosite consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Epidosite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Epidosite, the texture, color and appearance plays an important role in determining the type of rock. Wehrlite is available in dark greenish - grey, green colors whereas, Epidosite is available in black, brown, light to dark grey colors. Appearance of Wehrlite is Rough and Banded and that of Epidosite is Dull and Soft. Properties of rock is another aspect for Wehrlite vs Epidosite. The hardness of Wehrlite is 5.5-6 and that of Epidosite is 6. The types of Wehrlite are Ultramafic rock whereas types of Epidosite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wehrlite is white while that of Epidosite is white to grey. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Epidosite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Wehrlite is heat resistant, impact resistant, pressure resistant whereas Epidosite is heat resistant, pressure resistant, wear resistant.
