Archaeological Significance
Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

More about Charnockite and Laterite
Here you can know more about Charnockite and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Laterite 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 Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Charnockite vs Laterite, 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, Laterite is available in brown, buff, red colors. Appearance of Charnockite is Veined or Pebbled and that of Laterite is Rough and Banded. Properties of rock is another aspect for Charnockite vs Laterite. The hardness of Charnockite is 6-7 and that of Laterite is 2. The types of Charnockite are Enderbite whereas types of Laterite are Laterite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Charnockite and Laterite is white. The specific heat capacity of Charnockite is 0.84 kJ/Kg K and that of Laterite is 0.92 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 Laterite is heat resistant, pressure resistant.
