Archaeological Significance
Formation
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

More about Gabbro and Charnockite
Here you can know more about Gabbro and Charnockite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gabbro and Charnockite consists of mineral content and compound content. The mineral content of Gabbro includes Augite, Olivine, Plagioclase, Pyroxene 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 Gabbro vs Charnockite, the texture, color and appearance plays an important role in determining the type of rock. Gabbro is available in dark grey to black colors whereas, Charnockite is available in black, grey, orange, pink, white colors. Appearance of Gabbro is Veined and Shiny and that of Charnockite is Veined or Pebbled. Properties of rock is another aspect for Gabbro vs Charnockite. The hardness of Gabbro is 7 and that of Charnockite is 6-7. The types of Gabbro are Anorthosite Gabbro and Norite Gabbro 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 Gabbro is black while that of Charnockite is white. The specific heat capacity of Gabbro is 0.71 kJ/Kg K and that of Charnockite is 0.84 kJ/Kg K.
