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

More about Epidosite and Wehrlite

Here you can know more about Epidosite and Wehrlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Epidosite and Wehrlite consists of mineral content and compound content. The mineral content of Epidosite includes Olivine, Plagioclase, Pyroxene and mineral content of Wehrlite includes Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Epidosite vs Wehrlite, 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, Wehrlite is available in dark greenish - grey, green colors. Appearance of Epidosite is Dull and Soft and that of Wehrlite is Rough and Banded. Properties of rock is another aspect for Epidosite vs Wehrlite. The hardness of Epidosite is 6 and that of Wehrlite is 5.5-6. 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 Wehrlite are Ultramafic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Epidosite is white to grey while that of Wehrlite is white. The specific heat capacity of Epidosite is 0.84 kJ/Kg K and that of Wehrlite is 0.63 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 Wehrlite is heat resistant, impact resistant, pressure resistant.
