Archaeological Significance
Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

More about Charnockite and Eclogite
Here you can know more about Charnockite and Eclogite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Eclogite 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 Eclogite includes Amphibole, Coesite, Corundum, Dolomite, Garnet, Kyanite, Lawsonite, Paragonite, Phengite, Pyroxene, Quartz, Rutile, Zoisite. You can also check out the list of all Igneous Rocks. When we have to compare Charnockite vs Eclogite, 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, Eclogite is available in black, brown, green, grey, pink, white colors. Appearance of Charnockite is Veined or Pebbled and that of Eclogite is Dull, Banded and Foilated. Properties of rock is another aspect for Charnockite vs Eclogite. The hardness of Charnockite is 6-7 and that of Eclogite is 3.5-4. The types of Charnockite are Enderbite whereas types of Eclogite are Eclogite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Charnockite and Eclogite is white. The specific heat capacity of Charnockite is 0.84 kJ/Kg K and that of Eclogite is 0.75 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 Eclogite is heat resistant.
