Definition

Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine

Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

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.

Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

Norite vs Boninite 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 Boninite Reserves. Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine. Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction. 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 Boninite information and Norite vs Boninite characteristics in the upcoming sections.

More about Norite and Boninite

Here you can know more about Norite and Boninite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Norite and Boninite consists of mineral content and compound content. The mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite. You can also check out the list of all Igneous Rocks. When we have to compare Norite vs Boninite, 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, Boninite is available in bluish - grey, brown, green, grey colors. Appearance of Norite is Veined and Shiny and that of Boninite is Dull and Soft. Properties of rock is another aspect for Norite vs Boninite. Hardness of Norite and Boninite is 7. The types of Norite are Ultramafic intrusive rock whereas types of Boninite are Basalt. 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 Boninite is white. The specific heat capacity of Norite is 0.52 kJ/Kg K and that of Boninite 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 Boninite is heat resistant, impact resistant, pressure resistant, wear resistant.
