Formation
The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.
  
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

More about Appinite and Enderbite
Here you can know more about Appinite and Enderbite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Appinite and Enderbite consists of mineral content and compound content. The mineral content of Appinite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene 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 Appinite vs Enderbite, the texture, color and appearance plays an important role in determining the type of rock. Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas, Enderbite is available in black, grey, orange, pink, white colors. Appearance of Appinite is Dull, Banded and Foilated and that of Enderbite is Veined or Pebbled. Properties of rock is another aspect for Appinite vs Enderbite. The hardness of Appinite is 5-6 and that of Enderbite is 6-7. The types of Appinite are Not Available whereas types of Enderbite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Appinite and Enderbite is white. The specific heat capacity of Appinite is Not Available and that of Enderbite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Appinite is heat resistant, impact resistant whereas Enderbite is heat resistant, wear resistant.
