Adakite vs Norite


Definition

Definition
Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine  
Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs

Formation

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.  
Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.

Norite vs Adakite 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 Adakite Reserves. Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine. Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs. 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 Adakite information and Norite vs Adakite characteristics in the upcoming sections.

More about Norite and Adakite

Here you can know more about Norite and Adakite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Norite and Adakite consists of mineral content and compound content. The mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Adakite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Norite vs Adakite, 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, Adakite is available in black, brown, light to dark grey colors. Appearance of Norite is Veined and Shiny and that of Adakite is Dull and Soft. Properties of rock is another aspect for Norite vs Adakite. The hardness of Norite is 7 and that of Adakite is 3-4. The types of Norite are Not Available whereas types of Adakite are Not Available. 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 Adakite is bluish black. The specific heat capacity of Norite is Not Available and that of Adakite is Not Available. 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 Adakite is heat resistant, pressure resistant, wear resistant.
