Formation
Benmoreite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma. 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 Benmoreite and Charnockite
Here you can know more about Benmoreite and Charnockite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Benmoreite and Charnockite consists of mineral content and compound content. The mineral content of Benmoreite includes Alkali feldspar, Biotite, Olivine, Plagioclase, Pyroxene, Sodic plagioclase 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 Benmoreite vs Charnockite, the texture, color and appearance plays an important role in determining the type of rock. Benmoreite is available in black, brown, light to dark grey colors whereas, Charnockite is available in black, grey, orange, pink, white colors. Appearance of Benmoreite is Rough and Dull and that of Charnockite is Veined or Pebbled. Properties of rock is another aspect for Benmoreite vs Charnockite. The hardness of Benmoreite is 6 and that of Charnockite is 6-7. The types of Benmoreite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB) and Tholeiitic Basalt 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 Benmoreite is black while that of Charnockite is white. The specific heat capacity of Benmoreite is 0.84 kJ/Kg K and that of Charnockite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Benmoreite is heat resistant, pressure resistant, wear resistant whereas Charnockite is heat resistant, wear resistant.
