Formation

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.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

Epidosite vs Charnockite 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 Charnockite Reserves. Epidosite is a highly altered epidote and quartz bearing rock which is a type of metasomatite, essentially altered basalt. Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and feldspar. 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 Charnockite information and Epidosite vs Charnockite characteristics in the upcoming sections.

Epidosite vs Charnockite 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. Epidosite vs Charnockite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Epidosite and Properties of Charnockite. Learn more about Epidosite vs Charnockite in the next section. The interior uses of Epidosite include Decorative aggregates, Floor tiles, Homes, Hotels and Interior decoration whereas the interior uses of Charnockite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads. Due to some exceptional properties of Epidosite and Charnockite, they have various applications in construction industry. The uses of Epidosite in construction industry include As dimension stone, Cobblestones, Rail track ballast, Roadstone and that of Charnockite include As dimension stone.

More about Epidosite and Charnockite

Here you can know more about Epidosite and Charnockite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Epidosite and Charnockite consists of mineral content and compound content. The mineral content of Epidosite includes Olivine, Plagioclase, Pyroxene and mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Epidosite vs Charnockite, 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, Charnockite is available in black, grey, orange, pink, white colors. Appearance of Epidosite is Dull and Soft and that of Charnockite is Veined or Pebbled. Properties of rock is another aspect for Epidosite vs Charnockite. The hardness of Epidosite is 6 and that of Charnockite is 6-7. 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 Charnockite are Enderbite. 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 Charnockite is white. The specific heat capacity of Epidosite is 0.84 kJ/Kg K and that of Charnockite 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.Epidosite is heat resistant, pressure resistant, wear resistant whereas Charnockite is heat resistant, wear resistant.
