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.

Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.

Norite vs Aplite 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 Aplite Reserves. Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine. Aplite is a fine-grained granite composed mainly of feldspar and quartz. 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 Aplite information and Norite vs Aplite characteristics in the upcoming sections.

More about Norite and Aplite

Here you can know more about Norite and Aplite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Norite and Aplite consists of mineral content and compound content. The mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Aplite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Norite vs Aplite, 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, Aplite is available in black, grey, orange, pink, white colors. Appearance of Norite is Veined and Shiny and that of Aplite is Veined or Pebbled. Properties of rock is another aspect for Norite vs Aplite. The hardness of Norite is 7 and that of Aplite is 6.5. The types of Norite are Ultramafic intrusive rock whereas types of Aplite are Igneous rock. 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 Aplite is white. The specific heat capacity of Norite is 0.52 kJ/Kg K and that of Aplite is 0.79 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 Aplite is heat resistant, wear resistant.
