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

More about Granulite and Charnockite
Here you can know more about Granulite and Charnockite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Charnockite consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz and mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Charnockite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Charnockite is available in black, grey, orange, pink, white colors. Appearance of Granulite is Veined or Pebbled and that of Charnockite is Veined or Pebbled. Properties of rock is another aspect for Granulite vs Charnockite. Hardness of Granulite and Charnockite is 6-7. The types of Granulite are Not Available whereas types of Charnockite are Enderbite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite and Charnockite is white. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Charnockite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Granulite is heat resistant, wear resistant whereas Charnockite is heat resistant, wear resistant.
