Archaeological Significance
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.

Charnockite vs Granulite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Charnockite vs Granulite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Charnockite and Properties of Granulite. Learn more about Charnockite vs Granulite in the next section. The interior uses of Charnockite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads whereas the interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Charnockite and Granulite, they have various applications in construction industry. The uses of Charnockite in construction industry include As dimension stone and that of Granulite include As dimension stone, Building houses or walls.
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 Metamorphic rock. 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. The specific heat capacity of Charnockite is 0.84 kJ/Kg K and that of Granulite is 0.14 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 Granulite is heat resistant, wear resistant.
