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.

Mugearite forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

Norite vs Mugearite 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 Mugearite Reserves. Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine. Mugearite is a type of oligoclase bearing basalt, also comprising of olivine, apatite, and opaque oxides. 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 Mugearite information and Norite vs Mugearite characteristics in the upcoming sections.

More about Norite and Mugearite

Here you can know more about Norite and Mugearite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Norite and Mugearite consists of mineral content and compound content. The mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Mugearite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Norite vs Mugearite, 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, Mugearite is available in black, brown, light to dark grey colors. Appearance of Norite is Veined and Shiny and that of Mugearite is Dull and Soft. Properties of rock is another aspect for Norite vs Mugearite. The hardness of Norite is 7 and that of Mugearite is 6. The types of Norite are Ultramafic intrusive rock whereas types of Mugearite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. 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 Mugearite is white to grey. The specific heat capacity of Norite is 0.52 kJ/Kg K and that of Mugearite 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 Mugearite is heat resistant, pressure resistant, wear resistant.
