Formation

Formation

Norite 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.
Greenschist is medium grade metamorphic rock, formed by the metamorphosis of mudstone or shale, or some types of igneous rock, when it is subjected to higher temperatures and pressures.

Norite vs Greenschist 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 Greenschist Reserves. Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine. Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism. 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 Greenschist information and Norite vs Greenschist characteristics in the upcoming sections.

Norite vs Greenschist 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 Greenschist characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Norite and Properties of Greenschist. Learn more about Norite vs Greenschist in the next section. The interior uses of Norite include Decorative aggregates, Entryways and Interior decoration whereas the interior uses of Greenschist include Bathrooms, Countertops, Decorative aggregates, Entryways, Homes and Interior decoration. Due to some exceptional properties of Norite and Greenschist, 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 Greenschist include As dimension stone, Building houses or walls, Cement manufacture, Cutting tool, For road aggregate, Roadstone.

More about Norite and Greenschist

Here you can know more about Norite and Greenschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Norite and Greenschist consists of mineral content and compound content. The mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Greenschist includes Alusite, Amphibole, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Serpentine, Sillimanite, Staurolite, Talc. You can also check out the list of all Igneous Rocks. When we have to compare Norite vs Greenschist, 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, Greenschist is available in dark greenish - grey, green colors. Appearance of Norite is Veined and Shiny and that of Greenschist is Layered and Shiny. Properties of rock is another aspect for Norite vs Greenschist. The hardness of Norite is 7 and that of Greenschist is 3.5-4. The types of Norite are Ultramafic intrusive rock whereas types of Greenschist are Metamorphic rock. 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 Greenschist is white. The specific heat capacity of Norite is 0.52 kJ/Kg K and that of Greenschist 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 Greenschist is impact resistant, pressure resistant, water resistant.
