Epidosite vs Lherzolite 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 Lherzolite Reserves. Epidosite is a highly altered epidote and quartz bearing rock which is a type of metasomatite, essentially altered basalt. Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions. 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 Lherzolite information and Epidosite vs Lherzolite characteristics in the upcoming sections.

More about Epidosite and Lherzolite

Here you can know more about Epidosite and Lherzolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Epidosite and Lherzolite consists of mineral content and compound content. The mineral content of Epidosite includes Olivine, Plagioclase, Pyroxene and mineral content of Lherzolite includes Harzburgite, Olivine, Pyroxene, Pyrrhotite. You can also check out the list of all Igneous Rocks. When we have to compare Epidosite vs Lherzolite, 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, Lherzolite is available in black, dark greenish - grey, green, pink, purple colors. Appearance of Epidosite is Dull and Soft and that of Lherzolite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Epidosite vs Lherzolite. The hardness of Epidosite is 6 and that of Lherzolite is 6.5. 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 Lherzolite are Garnet Lherzolite. 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 Lherzolite is white. The specific heat capacity of Epidosite is Not Available and that of Lherzolite is 0.95 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 Lherzolite is heat resistant, impact resistant, pressure resistant, wear resistant.
