Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

More about Charnockite and Granulite
Here you can know more about Charnockite and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Granulite 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 Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Charnockite vs Granulite, 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, Granulite is available in black, brown colors. Appearance of Charnockite is Veined or Pebbled and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Charnockite vs Granulite. Hardness of Charnockite and Granulite is 6-7. The types of Charnockite are Enderbite whereas types of Granulite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Charnockite and Granulite is white.
