Archaeological Significance
Formation
Ijolite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

More about Ijolite and Enderbite
Here you can know more about Ijolite and Enderbite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Ijolite and Enderbite consists of mineral content and compound content. The mineral content of Ijolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite and mineral content of Enderbite 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 Ijolite vs Enderbite, the texture, color and appearance plays an important role in determining the type of rock. Ijolite is available in brown, buff, cream, green, grey, pink, white colors whereas, Enderbite is available in black, grey, orange, pink, white colors. Appearance of Ijolite is Banded and Foilated and that of Enderbite is Veined or Pebbled. Properties of rock is another aspect for Ijolite vs Enderbite. The hardness of Ijolite is 5.5-6 and that of Enderbite is 6-7. The types of Ijolite are Alkaline rock whereas types of Enderbite are -. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Ijolite and Enderbite is white. The specific heat capacity of Ijolite is 0.84 kJ/Kg K and that of Enderbite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Ijolite is heat resistant, impact resistant, wear resistant whereas Enderbite is heat resistant, wear resistant.
