Formation

Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of 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.

More about Charnockite and Norite

Here you can know more about Charnockite and Norite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Norite consists of mineral content and compound content. The mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz 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 Charnockite vs Norite, the texture, color and appearance plays an important role in determining the type of rock. Charnockite is available in black, grey, orange, pink, white colors whereas, Norite is available in dark grey to black colors. Appearance of Charnockite is Veined or Pebbled and that of Norite is Veined and Shiny. Properties of rock is another aspect for Charnockite vs Norite. The hardness of Charnockite is 6-7 and that of Norite is 7. The types of Charnockite are Enderbite 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 Charnockite is white while that of Norite is black. The specific heat capacity of Charnockite 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.Charnockite is heat resistant, wear resistant whereas Norite is impact resistant, pressure resistant, wear resistant.
