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

More about Norite and Enderbite
Here you can know more about Norite and Enderbite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Norite and Enderbite consists of mineral content and compound content. The mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Enderbite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Norite vs Enderbite, 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, Enderbite is available in black, grey, orange, pink, white colors. Appearance of Norite is Veined and Shiny and that of Enderbite is Veined or Pebbled. Properties of rock is another aspect for Norite vs Enderbite. The hardness of Norite is 7 and that of Enderbite is 6-7. The types of Norite are Not Available whereas types of Enderbite 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 Enderbite is white.
