Norite 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 Norite and Epidosite Reserves. Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine. 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 Norite vs Epidosite information and Norite vs Epidosite characteristics in the upcoming sections.

Norite vs Epidosite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Norite vs Epidosite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Norite and Properties of Epidosite. Learn more about Norite vs Epidosite in the next section. The interior uses of Norite include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Epidosite include Decorative aggregates, Floor tiles, Homes, Hotels and Interior decoration. Due to some exceptional properties of Norite and Epidosite, they have various applications in construction industry. The uses of Norite in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate and that of Epidosite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.

More about Norite and Epidosite

Here you can know more about Norite and Epidosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Norite and Epidosite consists of mineral content and compound content. The mineral content of Norite includes Augite, Olivine, Plagioclase, 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 Norite vs Epidosite, the texture, color and appearance plays an important role in determining the type of rock. Norite is available in dark grey to black colors whereas, Epidosite is available in black, brown, light to dark grey colors. Appearance of Norite is Veined and Shiny and that of Epidosite is Dull and Soft. Properties of rock is another aspect for Norite vs Epidosite. The hardness of Norite is 7 and that of Epidosite is 6. The types of Norite are Ultramafic intrusive 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 Norite is black while that of Epidosite is white to grey. The specific heat capacity of Norite is 0.52 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.Norite is impact resistant, pressure resistant, wear resistant whereas Epidosite is heat resistant, pressure resistant, wear resistant.
