Definition

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

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

Formation

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

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

More about Boninite and Norite

Here you can know more about Boninite and Norite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Boninite and Norite consists of mineral content and compound content. The mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite and mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Boninite vs Norite, the texture, color and appearance plays an important role in determining the type of rock. Boninite is available in bluish - grey, brown, green, grey colors whereas, Norite is available in dark grey to black colors. Appearance of Boninite is Dull and Soft and that of Norite is Veined and Shiny. Properties of rock is another aspect for Boninite vs Norite. Hardness of Boninite and Norite is 7. The types of Boninite are Basalt whereas types of Norite are Ultramafic intrusive rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Boninite is white while that of Norite is black. The specific heat capacity of Boninite is 0.84 kJ/Kg K and that of Norite is 0.52 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Boninite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Norite is impact resistant, pressure resistant, wear resistant.
