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 Charnockite
Here you can know more about Ijolite and Charnockite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Ijolite and Charnockite 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 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 Ijolite vs Charnockite, 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, Charnockite is available in black, grey, orange, pink, white colors. Appearance of Ijolite is Banded and Foilated and that of Charnockite is Veined or Pebbled. Properties of rock is another aspect for Ijolite vs Charnockite. The hardness of Ijolite is 5.5-6 and that of Charnockite is 6-7. The types of Ijolite are Not Available whereas types of Charnockite are Enderbite.
