Archaeological Significance
Formation
Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

More about Diorite and Charnockite
Here you can know more about Diorite and Charnockite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diorite and Charnockite consists of mineral content and compound content. The mineral content of Diorite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon 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 Igneous Rocks. When we have to compare Diorite vs Charnockite, the texture, color and appearance plays an important role in determining the type of rock. Diorite is available in black, brown, light to dark grey, white colors whereas, Charnockite is available in black, grey, orange, pink, white colors. Appearance of Diorite is Shiny and that of Charnockite is Veined or Pebbled. Properties of rock is another aspect for Diorite vs Charnockite. Hardness of Diorite and Charnockite is 6-7. The types of Diorite are Plagioclase Diorite and Quartz Diorite 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 Diorite is bluish black while that of Charnockite is white. The specific heat capacity of Diorite is 0.84 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.Diorite is heat resistant, pressure resistant, wear resistant whereas Charnockite is heat resistant, wear resistant.
