Formation

Formation
Kimberlite is an igneous rock and is the main source of diamonds. Its formation takes place deep beneath the Earth’s surface between 150 to 450 kilometres, and are erupted rapidly and violently.   
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.

Kimberlite 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 Kimberlite and Norite Reserves. Kimberlite is a rare, blue-tinged, coarse-grained intrusive igneous rock, which sometimes contains diamonds and is mostly found in South Africa and Siberia.. 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 Kimberlite vs Norite information and Kimberlite vs Norite characteristics in the upcoming sections.

More about Kimberlite and Norite

Here you can know more about Kimberlite and Norite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Kimberlite and Norite consists of mineral content and compound content. The mineral content of Kimberlite includes Garnet, Olivine, Phlogopite, Pyroxene 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 Kimberlite vs Norite, the texture, color and appearance plays an important role in determining the type of rock. Kimberlite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas, Norite is available in dark grey to black colors. Appearance of Kimberlite is Dull and Banded and that of Norite is Veined and Shiny. Properties of rock is another aspect for Kimberlite vs Norite. The hardness of Kimberlite is 6-7 and that of Norite is 7. The types of Kimberlite are Basaltic Kimberlites and Micaceous Kimberlites whereas types of Norite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Kimberlite is white while that of Norite is black. The specific heat capacity of Kimberlite is 0.92 kJ/Kg K and that of Norite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Kimberlite is heat resistant, impact resistant whereas Norite is impact resistant, pressure resistant, wear resistant.
