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.

Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.

Norite vs Peridotite 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 Peridotite Reserves. Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine. Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle. 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 Peridotite information and Norite vs Peridotite characteristics in the upcoming sections.

More about Norite and Peridotite

Here you can know more about Norite and Peridotite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Norite and Peridotite consists of mineral content and compound content. The mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Norite vs Peridotite, 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, Peridotite is available in dark greenish - grey colors. Appearance of Norite is Veined and Shiny and that of Peridotite is Rough and Shiny. Properties of rock is another aspect for Norite vs Peridotite. The hardness of Norite is 7 and that of Peridotite is 5.5-6. The types of Norite are Ultramafic intrusive rock whereas types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite. 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 Peridotite is white. The specific heat capacity of Norite is 0.52 kJ/Kg K and that of Peridotite is 1.26 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 Peridotite is heat resistant, pressure resistant, wear resistant.
