Definition
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.
Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and feldspar

Archaeological Significance
Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

Serpentinite vs Charnockite 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. Serpentinite vs Charnockite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Charnockite. Learn more about Serpentinite vs Charnockite in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Charnockite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads. Due to some exceptional properties of Serpentinite and Charnockite, they have various applications in construction industry. The uses of Serpentinite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement and that of Charnockite include As dimension stone.
More about Serpentinite and Charnockite
Here you can know more about Serpentinite and Charnockite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Charnockite consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides 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 Serpentinite vs Charnockite, the texture, color and appearance plays an important role in determining the type of rock. Serpentinite is available in black, brown, green, grey, white colors whereas, Charnockite is available in black, grey, orange, pink, white colors. Appearance of Serpentinite is Rough and Dull and that of Charnockite is Veined or Pebbled. Properties of rock is another aspect for Serpentinite vs Charnockite. The hardness of Serpentinite is 3-5 and that of Charnockite is 6-7. The types of Serpentinite are Jadeitite 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 Serpentinite and Charnockite is white, greenish white or grey. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Charnockite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Serpentinite is heat resistant whereas Charnockite is heat resistant, wear resistant.
